Lithium ion battery and anode strip thereof and stabilization lithium metal powder

The invention belongs to the technical field of a lithium ion battery, and particularly relates to stabilization lithium metal powder. The stabilization lithium metal powder has a core shell structure; and the core layer is formed by lithium metal and is a composition consisting of an electron good conductor and a lithium ion good conductor. Compared with the prior art, the stabilization lithium metal powder provided by the invention has the advantages that: in the process of performing pre-lithiation of the anode-active material by use of the stabilization lithium metal powder, no limitation is imposed on the pressure of the cold pressing process, the 'dead lithium' disabling lithiation reaction is not produced, and the lithiation efficiency of the lithium metal powder is improved; and moreover, since the shell layer left on the electrode surface has good electron and lithium ion conductivity after the pre-lithiation, the electron and ion conductivity of the anode can be effectively improved so as to improve the electrochemical performance of the battery. In addition, the invention also discloses an anode strip performing pre-lithiation by use of the stabilization lithium metal powder, and a lithium ion battery comprising the anode strip.

Lithium ion battery with electrolyte-embedded separator particles

A lithium ion battery in which electrically-non conducting ceramic particles are interposed between the anode and cathode to enforce separation between them and prevent short circuits is described. The particles, preferably equiaxed or monodisperse, may be generally uniformly dispersed in a non-aqueous gelled or high viscosity electrolyte. The electrolyte may be applied to one or both of the anode and cathode in suitable thickness to deposit the particles with the electrolyte and form a layered composite with substantially uniformly spaced particles suitable for holding the opposing anode and cathode faces in spaced-apart relation. The thickness of the applied electrolyte layer will be selected to enable deposition of the particles substantially as a fractional monolayer, a monolayer, or a multilayer as required for the application.
