Abstract: A lithium-ion battery component and pre-cured electrode are disclosed, featuring a current collector and a slurry containing graphite, silicon-based particles, and a chemically cross-linkable monomer. Upon initiation, the monomer chemically crosslinks to form a binder that mechanically binds the graphite and silicon-based particles, creating a coating adhered to the current collector the chemically crosslinked binder enables volume expansion during charging and facilitates volume contraction during discharging, maintaining some of the electrode's initial capacity. The chemically cross-linkable monomer is present at a weight percentage relative to the graphite and silicon-based particles, while the current collector is composed of a metal foil. The battery component and pre-cured electrode may increase performance and longevity in lithium-ion batteries through their chemically crosslinked binder and slurry composition.

Abstract: This disclosure relates to a lithium-ion battery with an enhanced electrode structure and methods for forming such an electrode structure. The electrode may comprise a metal current collector and a multi-layered active material coated thereon, which includes a discrete graphite-rich and a discrete silicon-rich layer. The silicon-rich layer is positioned between and in direct contact with the metal current collector and the graphite-rich layer.
