Lithium ion secondary battery |
摘要 |
A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles. |
