Putting It All Together: The Battery Pack
Finally, we have the battery pack: where the battery cells are all housed together, cooled via the cooling system and managed by the power management system . The overall frame will be made from a mix of metal and also plastic. The various components will be welded and/or bolted into place. The end result might look like the following Tesla batteries:

What Are Aa Batteries Made Of
A lot of people dont know this, but AA batteries are made of a very special material. Its a material that is both strong and flexible, which makes it perfect for use in batteries. The material is called lithium, and its found in a lot of different places.
Lithium is a metal, and its the lightest metal in the world. Thats why its used in a lot of different things, like laptop batteries and cell phone batteries. Its also why AA batteries are so light.
Lithium is also very reactive, which means that it can create a lot of energy. Thats why its used in batteries, because it can create a lot of power.
There are a lot of different types of lithium, but the most common type is lithium-ion. Lithium-ion batteries are the most popular type of battery, and theyre used in a lot of different devices.
AA batteries are made of lithium-ion, and theyre usually made of a mixture of different metals. The most common metals are cobalt, manganese, and nickel.
Lithium-ion batteries are very safe, but they can be dangerous if theyre not used properly. If you ever see a battery that is swollen or has leaked, dont use it.
If you have any questions about AA batteries, feel free to ask in the comments.
Battery Cells Made In
Tesla claims Giga Berlin will be the company’s most advanced and efficient facility yet. Apart from manufacturing Model Y cars at record speed, the Grünheide premise will also include a battery cell production plant meant to be the world’s largest such facility.
Musk has indicated the plant will have an annual production capacity of up to 100 gigawatt hours in an initial stage, which may later be expanded to 200 GWh. But even the planned capacity at the start would be enough to produce batteries for well over 1 million Model Y cars.
Experts expect Tesla to produce a new generation of 80 by 60 millimeter cells, promising higher energy density. Eventually, that would mean that the cars could extend their current range by 16%.

Understanding Tesla Battery Charge And Discharge Voltages
Nominal voltage is the number used to assign a class to a battery. You can think of it as the average of the battery’s working voltages. The actual charge and discharge rates vary and are measured as peaks and minimums.
The minimum rate defines how low a battery will discharge voltage. In the case of the new 2170 cell, the minimum voltage is 2.5 volts. The maximum voltage indicates the highest charge voltage that the battery will accept. In the case of the 2170 cell, it is 4.2 volts.
Producing The Battery Management System
At this point we have lots of battery modules, packed with all the power capacity that will be needed to move the car forward. However it would not be safe purely to hook this up to the motor controller and hope for the best: we need to ensure that the battery is safe in all conditions, and does not give out too much or too little power in any given situation .
The CEO of Daimler famously said in 2017 that:
The intelligence of the battery does not lie in the cell but in the complex battery system,.
Daimler CEO, 2017
In other words, we need a smart electrical component that can manage the huge amount of power that the EVs battery is storing away.
The actual BMS module will be a standard electrical component, with a PCB using silicon, and it will have a range of resistors and transistors . Naturally every car manufacturer will use their own BMS system, although an example to look at if you want more detailed information is the 12-Cell Lithium BMS Module from Zera . A general BMS module will look something like:
The battery/power management system is wired up to each battery module, allowing for the state of charge and state of capacity to be measured, along with a host of other safety and management measures. If you are interesting in electrics, then Renesas have a very handy guide on the specifics of a BMS.

What Happens To Electric Car Batteries After Theyre No Longer Usable Are They Recyclable
This is a great question! Its important to think about what happens to our electric car batteries after theyre no longer usable because, after all, we dont want to just throw them away and create more pollution.
The good news is that electric car batteries are recyclable! In fact, recycling electric car batteries is actually a pretty simple process.
First, the batteries are crushed into small pieces. Then, the small pieces are cleaned and smelted down to create new battery cells.
The recycling process of electric car batteries is actually quite efficient, and it helps to reduce the amount of pollution that would be created if the batteries were simply thrown away.
So, if youre wondering what happens to electric car batteries after theyre no longer usable, the answer is that theyre recycled!

Uncovering and explaining how our digital world is changing and changing us.
This story is part of Recode by Voxs Tech Support series, which explores solutions for our warming world.
When consumer lithium-ion batteries debuted in the 1990s, they were revolutionary: They recharged in a few hoursor less and made our modern computers and phones truly portable. But three decades later, this battery technology is due for a major upgrade, since the harsh reality of climate change means that lithium-ion batteries dont just need to power our devices, but our cars, too. Thats a lot harder.
Lithium-ion batteries became the go-to form of energy storage because they have an extremely high energy density, which means they can store a lot of energy within a relatively small volume. Lithium itself is thelightest metal on the periodic table, which makes lithium-ion batteries extra portable. As the technology has been incorporated into electric vehicles , though, these batteries have been pushed to their limit.
They can only be charged and discharged so many times, and we may have hit the upper limit of their storage capacity. This is one of the biggest concerns that people have with EVs since more capacity equals a longer driving range. Batteries also take up a huge amount of space in the cars that we already have, which means we cant just add more batteries to get more range.

What Is Anode Overpotential
Anode overpotential is an important factor in the performance of a metal-air battery. The overpotential is the voltage that must be applied to the anode in order to force the reaction of oxygen with the metal. The overpotential also determines the energy efficiency of the metal-air battery.
The overpotential of the anode can be reduced by using a catalyst, such as Pt or Pd, to increase the rate of the oxygen reduction reaction. The use of a catalyst also decreases the amount of charge that is required to be transferred to the anode in order to maintain a given current density.
The anode overpotential can also be decreased by using a higher surface area anode. A higher surface area anode will have a greater number of sites available for the reaction of oxygen with the metal.
The anode overpotential can be increased by increasing the concentration of oxygen in the cathode environment. The concentration of oxygen in the cathode environment can be increased by using a air cathode or by using an oxygen-containing electrolyte.
The anode overpotential can also be increased by increasing the rate of the oxygen reduction reaction. The rate of the oxygen reduction reaction can be increased by using a catalyst, such as Pt or Pd.
The anode overpotential can also be increased by using a lower surface area anode. A lower surface area anode will have a smaller number of sites available for the reaction of oxygen with the metal.
Tesla Will Live And Die By The Gigafactory
Inside the massive factory where Tesla will soon make 60 percent of the worlds lithium-ion batteries
Right now, in the desert just east of Reno, Nevada, Tesla is drilling into recently laid asphalt to install more electric vehicle chargers in the parking lot of the Gigafactory. The company has hired so many new workers in recent years that it needs more space to let them charge their Nissan Leafs, Chevy Bolts, Toyota Priuses, and, of course, Teslas. But before long, those chargers will be ripped right back out, along with the asphalt, and moved to a new spot to make room for more factory space.
Even though the Gigafactory isnt complete, its already enormous, taking up 1.9 million square feet of the land Tesla owns outside of Reno. Standing in the parking lot, it looms in my vision almost every way I look. Inside, some of the buildings gray hallways seem to stretch into oblivion. On the manufacturing floor which feels like a dizzying, oversized science experiment its stark white and Tesla red as far as the eye can see. A whir of robots and machines is only occasionally disrupted by the sound of human voices, creating the feeling that, somehow, this massive factory could drone on forever without much supervision.
The Gigafactory is enormous, but its also in a constant state of flux

Why Are Batteries Named The Way They Are
A group of professionals from the battery business, as well as representatives from many manufacturers and government organizations, convened in 1924 to create a uniform system of battery sizes. They decided to establish a common set of sizes using the letters of the alphabet. There were A,B,C,D,E, and so on batteries from the beginning.
Materials Within A Battery Module
As mentioned earlier, the module houses the individual cells and protects them from vibration and heat. The main container typically uses a mix of aluminium or steel, and also plastic.
The individual battery cells within the module need protection from heat and vibration, so a number of resins are used to provide mechanical reinforcement to the cells within the module:

The Economics Of Teslas Batteries Business
Tesla is a U.S. automotive and energy company based in Palo Alto, Calif. The company manufactures electric cars and solar panels as well as batteries and aeronautics. An SEC lawsuit heightened Tesla’s visibility in late 2018. The lawsuit alleged that Tesla’s CEO Elon Musk made “false and misleading statements” on Twitter about the possibility of taking the company private. Tesla’s share price fell by approximately 10% following the news of the lawsuit.
One of its manufactured products, batteries, deserves some attention, however. Supplier relationships and how battery-related revenue is doing can be a key driver for Tesla.
Munro Live Managed To Uncover An Entire Section
After days of hard work, the Munro Live team presents another stage of the teardown of the Made-in-Texas Tesla Model Y’s structural battery pack.
We already saw big progress in removing the pink polyurethane foam with a rented dry ice blaster and now we can see the current collector layout of one section of the battery , as well as the voltage sensor harness , and battery management system elements.
The new structural battery vastly differs compared to the other Tesla batteries .
The current collectors are welded directly to the 4680-type cylindrical battery cells, while in the case of other types, there were very small bonds between the cell and the current collectors. That sounds like simplification with a potential for cost reduction, as well as the elimination of potential failure points.
According to the video, the cells are grouped by 9 units . The bricks in the 2170-type pack counted several times more cells because they are smaller and have lower capacity. Each brick is connected to the BMS, which gets info about voltage and temperature.
Meanwhile, the first 4680-type cell has been finally extracted from the battery pack. Munro & Associates intends to collect most of the cells and sell them to offset some of the costs of the teardown. Considering how rare the 4680-powered Model Y is and how difficult it is to get into the cells, it actually might be a worthy item for OEMs, and research centers, as well as collectors and supporters.

Where Do Tesla Get Their Batteries From
Although graphite is a raw ingredient for battery manufacturers, Tesla produces some of its own batteries for use in its cars. The graphite is most likely coming from China, which is a major producer. EV companies, like Tesla, desire more regionally varied raw materials suppliers as the EV market expands.
Lithium: Where Does It Come From
Steering back to Tesla batteries, the push now is to make all batteries Lithium based batteries. This is the same type of battery that is in our other electronic devices, such as our phones and computers. Lithium batteries are rechargeable and have great capacity. Tesla batteries are comprised of individual cells which have been updated.
Each cell is just a smaller battery. Li-Ion batteries are constructed of lithium, cobalt, manganese, and graphite. There are also other materials used for the housing, like some plastics and other non-involved metals. The metals used as the electrodes are pressed flat into thin sheets and then rolled tightly together. A non-conductive spacer in between the two electrodes creates a power differential that is accessed by plugging it into the device.
Graphite primarily comes out of China, where it is also processed and treated for battery construction. Cobalt supply poses a significant risk to battery production as cobalt is very scarce even considering it comes out of North America, most of Asia, Australia, and some African countries. Manganese is commonly used in steel production with only about 0.2% of all manganese extracted worldwide being used in batteries.

How Are Batteries Made
Similarly, What materials are used to make a battery?
A number of metals and electrolytes are used in commercially accessible batteries. Zinc, aluminum, lithium, cadmium, iron, metallic lead, lanthanide, or graphite may be used as anodes. Manganese dioxide, mercuric oxide, nickel oxyhydroxide, lead dioxide, and lithium oxide may all be used as cathodes.
Also, it is asked, What 3 things make up a battery?
To generate power, a conventional battery requires three components: The anode is the batterys negative side. The positive side of the battery is called the cathode. Chemical paste that separates the anode and cathode and converts chemical energy into electrical energy.
Secondly, Where does Tesla get its lithium?
Musk has mentioned extracting its own lithium before, including in a tweet on Friday. According to Fortune, which cited people familiar with the subject,Tesla won its own rights to mine lithium in Nevada in 2020 after a plan to purchase a lithium mining business fell through.
Also, Are Tesla batteries recyclable?
When Tesla battery packs approach the end of their useful life, what happens to them? Unlike fossil fuels, which emit toxic pollutants that cannot be collected for reuse, the materials in a Tesla lithium-ion battery can be recovered and recycled.
