The invention discloses a lithium ion battery safe to use, including a positive electrode, a diaphragm and a negative electrode, the positive electrode, the diaphragm and a negative electrode are combined to form a battery, the diaphragm is located between the positive electrode and the negative electrode, the material of the positive electrode is lithium manganate, the material of the negative electrode is carbon microsphere, the outer surface of the positive electrode and the outer surface of the negative electrode are provided with a housing, the housing comprises an abrasion-resistant layer, an insulating layer, a waterproof layer, an insulating layer, a flame-retardant layer and a tensile layer, wherein the abrasion-resistant layer is located on the top of the insulating layer, the insulating layer is located on the top of the waterproof layer, the waterproof layer is located on the top of the heat-insulating layer, the heat-insulating layer is located on the top of the flame-retardant layer, and the flame-retardant layer is located on the top of the tensile layer. The present invention solves the problem that the lithium ion battery is not safe when in use and is prone to accident through the housing, the abrasion resistant layer, the insulating layer, the waterproof layer, the heat insulating layer, the flame retardant layer, the tensile layer, the positive electrode, the separator and the negative electrode.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a safe lithium ion battery. Background technique [0002] Lithium-ion battery: It is a secondary battery (rechargeable battery), which mainly relies on the movement of lithium ions between the positive electrode and the negative electrode to work. During the charge and discharge process, lithium ions are intercalated and deintercalated between the two electrodes: When charging, lithium ions are deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Lithium-ion batteries are used in mobile phones and laptops. People usually call it a lithium battery. The battery generally uses lithium-containing materials as electrodes, which is a represent...
