Description

Technical Field

[0001] The invention belongs to the technical field of battery production, and in particular relates to a high-efficiency conversion green energy-saving lithium manganese oxide battery. Background Art

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. In 1912, lithium metal battery was first proposed and studied by Gilbert N.Lewis. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Lithium manganate battery refers to a battery with lithium manganate material as the positive electrode. The nominal voltage of lithium manganate battery is 2.5~4.2v. Lithium manganate battery is widely used for its low cost and good safety; low cost, safety and low temperature performance of the positive electrode material, but the material itself is not very stable and is easy to decompose and produce gas, so it is often used in combination with other materials to reduce the cost of the battery cell, but its cycle life decays quickly, it is easy to bulge, the high temperature performance is poor, and the life is relatively short. It is mainly used for large and medium-sized batteries. In terms of power batteries, its nominal voltage is 3.7V.

[0003] However, when multiple common lithium batteries are connected together for use, if improper force is applied, the battery is prone to bursting, which affects the convenience of using the battery. At the same time, the lack of internal protection measures in ordinary batteries causes the battery to be damaged when it is dropped, thus affecting the battery life. In addition, the shape of common ordinary batteries cannot be changed during use, so people will encounter problems in coping with different usage scenarios early in the process of use.
