Abstract:
An active material layer for an electrode of a lithium ion battery has a first active material comprising silicon-based particles, a second active material comprising graphite and conduits between the first active material and the second active material, the conduits being a conductive material and providing area for expansion of the first active material due to lithiation while maintaining contact between the first active material and the second active material.
