Produced in partnership with panasonic at the nevada gigafactory tesla s 2170 lithium ion battery modules proved to be one of the sources of the model 3 s production bottlenecks last year.
Panasonic 2170 battery cell.
Panasonic has developed new battery technology for the 2170 lithium ion cells it produces and supplies to tesla a change that improves energy density by 5 and reduces costly cobalt content.

Tesla and panasonic have now developed a new and improved type of cell which will be used in the upcoming model 3.

Panasonic corp plans to boost the energy density of 2170 battery cells it supplies to tesla inc by 20 in five years and commercialize a cobalt free version in two to three years.

Panasonic s battery cell.
Panasonic corp 6752 t plans to boost the energy density of 2170 battery cells it supplies to tesla inc tsla o by 20 in five years and commercialize a cobalt free version in two to three.
However 18650 cell is very limited by its size volume which is generally between 2 0 2 6ah cell for mass production.
The new integrated battery module concept is using the same 2170 format as tesla and panasonic s new cell but the company is referring to it by the more traditional 21700.
The new 2170 cell which is now being produced at the gigafactory is slightly larger 21 mm by 70 mm.
The 2170 cell is around 50 larger by volume than the 18650 but it can deliver almost double the current the 18650 delivers 3 000 ma and the 2170 has been tested at 5 750 6 000 ma.
