Tesla 2170 battery cells are about 50 percent more energy dense than the previous 18650 cells.
Tesla 18650 battery cell.
While panasonic tesla s battery cell manufacturers.
To expand production and sales of products tesla activates the development of model 3 which is expected to cost about half of the current basic model of tesla about 200 miles.
Tesla and panasonic have now developed a new and improved type of cell which will be used in the upcoming model 3.
The maximum charging voltage for a panasonic cell is 4 2 volts.
They are rated at 500 amps 750 amps peak.
Plans to use 20700 high performance lithium cobalt acid batteries to replace the panasonic 18650 battery cells which is now widely used on tesla cars to improve the performance of the model 3 new cars.

The new 2170 cell which is now being produced at the gigafactory is slightly larger 21 mm by 70 mm.
18650 battery these batteries are used in the tesla models x and model s.
The tesla battery packs using panasonic 18650 batteries can charge no faster than this.
With the design of its early vehicles tesla was not a big enough player in the battery market to be able to design the ideal battery cell and instead used the next best thing standard 18650.
Tesla allows charging current to be up to 4 amperes.
These are currently the best battery on the market for energy density allowing many classic conversions to get well over 200 miles per charge.
This battery cell is smaller and lighter than the 21700 form factor.
Panasonic specifies a maximum charging current of 2 amperes per cell.
Each battery cell weighs between 60 to 65g and is 70mm long with a 21mm diameter.
Tesla s older 18650 battery image.
Model s modules are comprised of 3400mah cells arranged in a 74p6s configuration.
This cell is a lithium ion rechargeable battery with a capacity of 2200 to 3600 mah.
