Lithium titanate power battery

Abstract

The invention provides a lithium titanate power battery. The battery comprises an anode current collector, an anode active material coated on the anode current collector, a cathode collector, a cathode active material coated on the cathode current collector and a diaphragm positioned between the anode current collector and the cathode current collector, wherein a lithium titanate power battery isformed after electrolyte is injected into the anode current collector, the diaphragm and the cathode current collector; the anode active material is nickel lithium manganese oxide, and the cathode active material is lithium titanate; the electrolyte is prepared from organic solvent, lithium salt, a cathode film-forming agent and functional additives; and the functional additives is prepared from 0.1-5 mass percent of allyl thiocyanate and 2-10 mass percent of ethyl 3-trimethylsilyl propanoate. The lithium titanate power battery has excellent circulation performance, high capacity retention rate, excellent charging and discharging performance and high energy density.
