Panasonic To Increase Tesla Battery Cell Energy Density By 20%


Imagine owning a Tesla vehicle that can drive over 1000 miles on a single charge and can last a million miles.

In this exclusive piece reported by Reuters, Panasonic Corp wants to increase the energy density of the 2170 battery cells it supplies to Tesla by 20% in five years and commercialize a cobalt-free version “in two to three years”, the head of its U.S. EV battery business said.

A 20% increase in the energy density of the battery cells is going to be huge once realized.

The 2170 battery, which according to researchers already has the highest energy density at above 700Wh/liter, was introduced in 2017 for Tesla Model 3 vehicles. The battery has lithium-ion cells, with the nickel-cobalt-aluminum (NCA) cathode chemistry.

On the 22nd of September, Tesla is set to announce a ground-breaking battery technology that has been a top-secret till now. The secret battery technology breakthrough promised by the CEO Elon Musk, developed with China’s CATL, can make an electric vehicle drive a million miles.

While CATL is already supplying Tesla with low-cost lithium iron phosphate (LFP) batteries that contain no cobalt, Panasonic has cut cobalt content to under 5% in the NCA cathode. This is possibly one of the reasons Tesla is betting big on CATL batteries and has also decided to work with LG Chem.

Tesla is presently looking for a Production Associate that will work alongside engineers on the new pilot line, while they construct a new battery production facility in Fremont USA and Germany.
