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.
