3M has pioneered the development of revolutionary silicon anode compositions. With twice the volumetric and gravimetric energy density of graphite anodes, lithium ion battery silicon anode materials can increase cell energy up to 40%, depending on cathode energy density and cell design.
3M silicon anode materials have shown excellent cycling and high rate characteristics suitable for a wide variety of consumer electronic applications. Thermal stability of anode Si compositions are comparable to conventional graphite systems. In addition, 3M water based coating formulations have been designed to fit into conventional graphite coating processes for simplified manufacturing.
