Panasonic: Tesla batteries should receive 20% more energy density-batteries

For months, Tesla boss Elon Musk attracts investors and competitors with the promise to introduce a “battery day” breakthrough progress in battery technology. Tesla battery supplier Panasonic came before him. At least, the director of the US electric car battery business announced that the company is planning the energy density of “2170” battery cells to increase 20% in five years and to market a cobalt-free version “in two to three years”.

This message has nothing to do with the Roadrunner project of Tesla at Hut. But still means progress for the e-automaker. The RoadRunner battery project should bring the prices of Tesla electric cars to the level of comparable combustion. The new “million miles” battery, which is to be in the center of Tesla‘s future strategy, was developed together with China’s Contemporary Amperex Technology Ltd (Catl) and sets technology developed by Tesla in collaboration with a team of selected battery experts. The cobalt for this is already secured.

But back to the current Panasonic message. With the statement of the senior employee, the company first includes positioning, outriding medium-term goals and can show all the journey. Panasonic has introduced the “2170” lithium-ion cells with the nickel-cobalt aluminum (NCA) cathode chemistry for Teslas Model 3 in 2017. Researchers say that with more than 700 watt hours per liter already has the highest energy density. With the introduction of Model Y, Panasonic then saw problems with the battery supply. Possibly with one reason why Tesla is now also relevant to other suppliers.

It establishes that with even higher density these cells could help to bring more range with the same battery size. Alternatively, smaller batteries can be installed, which at the same time reduces the price of later e-cars. Potential seems to be enough, as the company gave to understand already some time ago. Put one more on it would be Panasonic with the cobalt-free battery, which would significantly minimize dependence on a costly and controversial component.

However, the company rejected it to link its battery roadmap with the future models of Tesla. Panasonic recently lost its status as an exclusive battery supplier of Tesla, as already mentioned. The US company has entered into a partnership with the South Korean LG Chem and the Chinese company Catl. From September, Panasonic will begin in his factory in Nevada, which operates it with Tesla, with the conversion of the lines, while it is prepared to further increase the energy density of the cells.
