Panasonic Corp recently announced that it plans to boost the energy density of the 2170 lithium-ion battery cells that it supplies to Tesla by 20 per cent over the next five years. The cells are currently made with nickel-cobalt-aluminum cathode chemistry, and Panasonic has set targets to commercialize a cobalt-free version of the battery cells in the next two to three years. The increased density of the cells can improve the running time of an electric vehicle on a single charge, while also allowing for smaller battery size, which could result in larger interiors. Currently, the Tesla Model 3 has the highest energy density on the market, above 700 watt-hour per litre. (Source: Reuters) Read the original article…
