HETEROJUNCTION NANOMATERIAL, CATHODE POLE PIECE FOR LITHIUM-ION BATTERIES, AND LITHIUM-ION BATTERY

摘要

Provided are a heterojunction nanomaterial, a cathode pole piece for lithium-ion batteries, and a lithium-ion battery. The heterojunction nanomaterial comprises a MoO3nanobelt and a metallic oxide, having an alloy-type lithium-intercalated mechanism, covered on the surface of said MoO3 nanobelt. The cathode pole piece for lithium-ion batteries uses the heterojunction nanomaterial as the active material. A lithium-ion battery using said cathode pole piece for lithium-ion batteries has high reversible specific capacity and high cycle stability.
