Title:
HYBRID ELECTRODES AND ELECTROCHEMICAL CELLS AND MODULES UTILIZING THE SAME
Document Type and Number:
WIPO Patent Application WO/2019/204964
Kind Code:
A1
Abstract:
Hybrid electrochemical cells and modules include an anode two-sided current collector a coated with host material in anode region (s) and a cathode two-sided current collector coated with active material in cathode region (s), and one or more of the anode current collector and the cathode current collector is coated with capacitor material in one or more distinct, non-overlapping capacitor regions. A hybrid anode and/or cathode can include gaps between capacitor regions and anode regions and cathode regions. The capacitor material applied to an electrode is different from the host or active material thereof. Active material includes lithium metal oxides and lithium metal phosphates such as LiFePO4, Li (NixMnyCoz) O2, and/or LiMn2O4; host material includes graphite, silicon, silicon-Li/Sn/Cu alloys, Si/Co/Fe/TiSn oxides, and low-surface area carbon; and capacitor material includes activated carbon, metal oxides, and metal sulfides.
