摘要:
A lithium ion capacitor, including: an anode including: a conductive support; a first mixture coated on the conductive support including: an interclating carbon; a conductive carbon black; and a PVDF binder in amounts as defined herein, and where the PVDF binder has a weight average molecular weight of from 300,000 to 400,000; and a second mixture coated on the first mixture, the second mixture comprising micron-sized lithium metal particles having an encapsulating shell comprised of LiPF6, mineral oil, and a thermoplastic binder. Also disclosed is a method of making and using the lithium ion capacitor.
