Abstract
Single Li-ion conducting solid-state polymer electrolytes for use in energy storage devices are disclosed. The energy storage device comprises a first electrode and a second electrode, where at least one of the first electrode and the second electrode is a Si-based electrode, a separator between the first electrode and the second electrode, and an electrolyte. Electrolytes may include all-solid-state polymer electrolytes, quasi-solid polymer electrolytes and/or polymer gel electrolytes. The single Li-ion conducting solid-state polymer electrolytes can improve the electrochemical performances and safety of Si anode-based Li-ion batteries.
