Abstract
A polyimide-based lithium ion battery is presented. The battery comprises at least one anode and at least one ionically conductive and electrochemically active cathode; or at least one ionically conductive and electrochemically active anode and a cathode; or at least one ionically conductive and electrochemically active anode and at least one ionically conductive and electrochemically active cathode. The source of the ionic conductivity and electronic activity. in either the anode, the cathode (or both) lies in a solid electrolyte polyimide binder comprising a lithium salt and a pre-imidized soluble, amorphous, thermoplastic polyimide powder. The batteries of the present invention do not require adhesives or interlayer bonding which may fail and they have at least one ionically conductive and electrochemically active electrode, enhancing the overall performance of the battery.
