A 21mm diameter cylinder with a height of 70mm equates to ~2,307mm. I believe the new 4680 packs will have higher capacity simply because the pack is taller due to the increased height of the cells. Tesla uses various battery types, including the 2170 and the 4680. This 76 kWh number agrees with Jack Rickards estimate of a usable energy of the pack equal to 76 kWh and a cell amp hour rating of 4.8 a-hr (@13:33, 47:50 and 51:31 here). As far as size goes there is no significant advantage to a larger size over a smaller size battery as the proportion of space between them remains the same. What Percentage Should I Charge A Tesla Battery? Panasonics 18650 battery cell was an industry standard with a proven record of performance that was being produced in large numbers. Tesla Model 3 2170 Energy Density Compared To Bolt, Model S P100D However, all good things must come to an end. The new 4680-format cylindrical cells46 millimeters wide by 80 millimeters longwas presented at Tesla's Battery Day last year and are expected to be used in certain future Tesla vehicles. That puts energy density by weight for one Tesla 18650 P100D cell at 11.9/.0475=, And volumetric energy density at 11.9/.0165 liters=. Dissecting Tesla Model 3s 2170 lithium ion battery cell, whats inside? The New 21700 format Lithium Cells in 2017 - ElectricBike.com But how much? New technology . 2.1. battery energy density can be increased by more than 20%. 246 watt-hours/kg. It allows them to make cordless versions of tools we would never have imagined possible even a decade ago. The link to download the report is below-its free. We will use 57 kWhs in our calculation. We will calculate the cell energy density based on usable energy= usable energy density of the pack divided by the number of cells. Good day .
