Embodiment 1

[0027] The present invention discloses a two-phase electrolyte lithium battery, including a housing 1, a positive electrode material 2, a negative electrode material 3, a liquid electrolyte 4, and a diaphragm 5. Among them, the positive electrode material 2 is provided in the inner wall of the upper end of the outer casing 1, and the specific positive electrode material 2 can be used for lithium nickel-chanmentedmented acid 2. The negative electrode material 3 is also a plurality of and intervals disposed in the inner wall of the outer casing 1, and the specific negative electrode material 3 can be used for carbon.

[0028] The diaphragm 5 is disposed in the outer casing 1 between the positive electrode material 2 and the negative electrode material 3, and the diaphragm 5 is selected from the polyolefin porous film, and the specific selective polyethylene or polypropylene porous semi-permeable film is selected. The liquid electrolyte 4 is filled in the inner cavity of the outer ca...

Abstract

The invention relates to the technical field of lithium batteries, and particularly discloses a biphase electrolyte lithium ion battery. The biphase electrolyte lithium ion battery comprises a shell, a positive electrode material, a negative electrode material, liquid electrolyte and a diaphragm, wherein the positive electrode material is arranged on the inner wall of the upper end of the shell, the negative electrode material is arranged on the inner wall of the lower end of the shell, the diaphragm is arranged in the shell between the positive electrode material and the negative electrode material, and the liquid electrolyte is filled between the positive electrode and the diaphragm, between the diaphragm and solid electrolyte, between the solid electrolyte and the negative electrode and between the diaphragm and the negative electrode material. By additionally arranging a layer of solid electrolyte between the negative electrode and the diaphragm of the lithium ion battery, and the puncture effect of dendritic crystals formed by lithium ions on the negative electrode on the diaphragm is effectively eliminated due to the arranged solid electrolyte, the service life of the battery is greatly guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of lithium batteries, and a two-phase electrolyte lithium battery is disclosed. Background technique [0002] Lithium ion batteries are the most representative energy storage devices in the new energy field, which occupy an unsubstitutable position in the mobile electronic product power supply device. [0003] Conventional lithium batteries are mainly composed of housing, positive and negative, liquid electrolytes, and membranes. For example, the invention is disclosed in the invention of CN201210108643.9, a capacitance-lithium ion secondary battery is disclosed. A capacitance-lithium ion secondary battery, including a housing, a positive terminal, and a negative electrode terminal, further comprising a diaphragm, an electrolyte, a positive electrode foil, and a diaphragm separating the inner cavity of the outer casing into a positive electrode chamber A and a negative pole B; positive electrode chamber T...
