Abstract: The present application provides a coated anode material and a method of preparing the same. The coated anode material has a core-shell structure, wherein the core-shell structure includes an inert core and a shell coated on the inert core, the shell comprises an anode active material, and the inert core comprises a non-active material. In the coated anode material, the anode active material of the shell is distributed over the non-active material of the inert core, and the coated anode material can overcome the volume change problem of silicon particles during lithium insertion/deinsertion to a certain extent and obtain a better cycle performance and rate performance.

Abstract: A lithium-ion battery comprises a positive electrode, a negative electrode, an electrolyte system and an ion-selective conducting layer disposed between the positive electrode and the negative electrode. The ion-selective conducting layer consists of high polymers and an inorganic lithium salt having lithium-ion conductivity, or consists of the inorganic lithium salt. The inorganic lithium salt includes LimMnOx, wherein the values of the m and n ensure the LimMnOx an electrically neutral compound, M is selected from at least one of B, P, Si, Se, Zr, W, Ti, Te, Ta, Al and As. The lithium-ion battery has a conduction layer having preference-selective conductivity for the lithium ions and disposed between the positive electrode and the negative electrode. The selective-conduction layer has improved mobility for lithium ions. Metal ions generated from the oxidized metal current collector at the negative electrode due to the over-charging of the battery can be blocked.
