Abstract
Silicon particles for use in an electrode in an electrochemical cell are provided. The silicon particles can have surfaces providing an average contact angle less than about 87.2°. The silicon particles can also have outer regions extending about 20 nm deep from the surfaces. The outer regions can include an amount of aluminum such that a bulk measurement of the aluminum comprises at least about 0.01% by weight of the silicon particles.
