Tesla 18650 battery cell specs.

The panasonic 18650 cell was already state of the art. The 18650 cell is a li ion type battery which has found its application in many fields such as portable electronics like torch lights electric vehicles cars like tesla and much more. Nowadays you can find 18650 batteries in a plethora of products from chainsaws and scooters to even a tesla model x. That s right since 2013 the battery packs of a tesla contains 7 104 individual 18650 cells which stores up to 85kwh of energy or enough juice to power a full size car.

We think jack rickard used an older 18650 cell in his calcs ref 51 31 he stated that the 2170 s energy density was better than the 18650 s. Tesla 2170 battery cells are about 50 percent more energy dense than the previous 18650 cells. These are currently the best battery on the market for energy density allowing many classic conversions to get well over 200 miles per charge. The most important product tesla has developed so far that will be used from powering homes to space travel.

They are rated at 500 amps 750 amps peak. Understanding different li ion specifications. Tesla is hoping to produce the cells at about the same cost. Note that these numbers are on cell level only in a battery pack you also need interconnections control hardware and cooling.

As outlined in hughes s blog post tesla was able to fit more of its cylindrical 18650 lithium ion battery cells into each of the 16 modules making up the p100d battery. More 18650 battery cells. If they reach a capacity of 6 000 mah per cell the improvement rises to 20. The good thing about 18650 batteries was that these were commodity lithium ion battery cells and allowed tesla to purchase reliable cells from its battery supplier panasonic at the scale it.

We see a 15 increase in volume density and a 15 increase in weight density. Tesla s old versus new battery format. In 2015 panasonic altered the anode design increasing cell capacity by about 6 enabling the battery packs to store up to 90 kwh of energy. Model s modules are comprised of 3400mah cells arranged in a 74p6s configuration.
