Abstract
A system and method of forming a silicon-hybrid anode material. The silicon-hybrid anode material including a microparticle mixture of a quantity of silicon microparticles and a quantity of metal microparticles intermixed with the quantity of silicon microparticles in a selected ratio. The microparticle mixture is formed in a silicon-hybrid anode material layer having a thickness of between about 2 and about 15 μm.
Claims9
A method comprising:
- forming a quantity of silicon microparticles;
- forming a quantity of metal microparticles such that a size of the metal microparticles is substantially equal to that of the silicon microparticles;
- obtaining a quantity of at least one polymer binder material;
- mixing the quantity of silicon microparticles, the quantity of metal microparticles, and the quantity of at least one polymer binder material in a selected ratio to form a microparticle mixture, wherein the quantity of at least one polymer binder material is between about 5 percent and about 10 percent by weight of the microparticle mixture;
- heating the microparticle mixture until the quantity of at least one polymer binder material is substantially evaporated away;
- and
- forming the microparticle mixture into a silicon-hybrid anode material layer having a thickness of between about 2 micrometers and about 15 micrometers.
