High safety lithium battery

Abstract

The present invention discloses a high safety lithium battery. With the high safety lithium battery, in the case of no influence on the chemical properties of the single pack lithium battery sheet, the safety problems of the acupuncture outside the lithium battery or the short circuit inside the lithium battery, and reduction of the heat inside the lithium battery and the battery deformation can be well solved. The high safety lithium battery comprises a lithium battery body, wherein the lithium battery body comprises a plurality of single pack lithium battery sheets, the plurality of the single pack lithium battery sheets are connected in series, circuit-breakers are respectively connected on the connection wire of the adjacent two layers of the single pack lithium battery sheets in series, a heat insulation sealing cloth layer is wrapped on the outer side surface of the single pack lithium battery sheet, a number 1 protection mesh layer is wrapped on the outer surface of the heat insulation sealing cloth layer, a main glue is sealed inside each mesh of the number 1 protection mesh layer, a number 2 protection mesh layer is wrapped on the outer surface of the number 1 protection mesh layer, and an assisted glue is sealed inside each mesh of the number 2 protection mesh layer. The high safety lithium battery is mainly used in the lithium battery technology.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery with high safety. Background technique [0002] With the global energy crisis, especially as my country has become the world's largest automobile consumer, problems such as energy shortage and environmental pollution have become increasingly prominent. The world is gradually transforming the original energy consumption structure and using energy more rationally and effectively. Lithium-ion power batteries, which have the advantages of high energy density, long cycle life, and no pollution, have become one of the inevitable choices for the future automotive industry. [0003] However, during the use of lithium-ion power batteries, it is easy to cause extrusion, vibration, high temperature and even internal short circuit inside the battery pack. This causes the battery to heat up inside, smoke, catch fire and even explode. Bring huge property and pers...
