Abstract: The disclosure describes nano-lithium-ion batteries having a cathode, an anode including lithium titanium oxide nanoparticles, a separator including silicon dioxide nanoparticles and an electrolyte. In a preferred embodiment, the cathode is composed of 70-95 wt % lithium cobalt oxide, 1-6 wt % of a conductive carbon, and a synthetic resin including at least one thermoplastic; the anode is composed of 75-90 wt % lithium titanium oxide nanoparticles, 1-5 wt % of a conductive carbon, and a synthetic resin including at least one thermoplastic; and the separator is composed of silicon dioxide nanoparticles and a synthetic resin comprising at least one thermoplastic. The disclosure also describes methods of manufacturing the nano-lithium-ion batteries.

Abstract: This invention is related to a process for preparing polymeric Li-ion cell with high-capacity as well as the cells manufactured with the process. The process produces anode paste with lithium salt and cobalt oxide and sprays the paste onto aluminum current collector to form the anode; produces cathode paste with two lithium-embedded carbon materials and sprays the paste to copper current collector to form the cathode; produces a paste with polyvinylidene fluoride, silicon dioxide (gas phase), o-dibutyl phthalate ester, and acetone and sprays the paste onto a polyester film to form the diaphragm; performs extraction for the cell assembled with said anode, diaphragm, and cathode, welds lugs, immerses the cell into electrolyte to, and packs the cell with aluminum-plastic composite film, and finally performs formation for the cell, so that a polymeric Li-ion cell with high-capacity is accomplished.
