Abstract:
A method of making an electrode for a lithium ion battery includes providing a restricting media having a main body with opposing planar surfaces and depositing alloying particles on the opposing planar surfaces to form a restrained active particle layer. The restricting media can be a magnetic, electrochemically inactive material with an affinity for the alloying particles. The restricting media restrains expansion of the alloying particles during lithiation to a respective side of the restricting media. Electrodes include a current collector and an electrode material layer adjacent the current collector including the restricting media, the alloying particles deposited on the restricting media to form a restrained active particle layer, and a carbon material in contact with the alloying particles.
