Process development for silicon to lithium battery anodes

Offentlig prosjektsammendrag

Through R&D work, Elkem will introduce a Si(M)/C mix suited for anode material in Li-batteries with a verified quality in half and full cell tests that satisfies minimum 800 mAh/g anode and more than 1500 cycles in both laboratory and industrial scale experiments. According to published statistics, transportation is the fastest growing market. Energy storage in smart grids and renewable power plants also represents market opportunities since intermediate energy storage is necessary for e.g. solar and wind energy. In addition, the consumer electronics is in continuous growth. The demand for batteries with higher energy density and improved safety can be solved by using silicon. Elkem has selected to target batteries for transportation and consumer electronic where it is believed that silicon will be introduced in the coming years. The project will establish production facilities in Elkem for different silicon based materials for battery and IPR will be monitored and secured when necessary.
