摘要:
Anodes for lithium-ion batteries and methods for their production are provided. Anodes comprise an initial anode made of consolidated anode material particles, and a coating of the initial anode, that comprises a layer of an ionic-conductive polymer which provides an artificial SEI (solid-electrolyte interphase) to facilitate lithium ion transfer through the coating while preventing direct fluid communication with the anode material particles and electrolyte contact thereto. The coating may be configured to keep the anode resistance low while preventing electrolyte decomposition thereupon, enhancing cell stability and cycling lifetime.
