Nano-porous silicon for high-energy silicon-dominant batteries

A major improvement for the next generation of Li-ion batteries is the introduction of silicon as material for the anode, bringing capacity and fast charging to the next level. The biggest challenge of applying silicon-dominant anodes in Li-ion batteries, is silicon's tendency to expand during cycling.

E-magy has invented and manufactures micron-sized silicon particles with nanopores that overcome this challenge by containing that expansion within the nanopores themselves. Li-ion batteries with anodes made of E-magy silicon hold 40% more energy than those made of graphite. It's the low-cost, drop-in solution compatible with existing production lines that the EV industry needs – as currently verified by R&D managers of more than a dozen leading automotive and battery manufacturer brands.
