Abstract

The invention relates to a fire prevention layer with a composite structure and a battery system using the fire prevention layer, and relates to the technical field of batteries. The fire prevention layer with the composite structure and the battery system using the fire prevention layer comprise the fire prevention layer, a skeleton layer, a heat insulation layer, an impact-resistant layer, an adhesive, a battery system box cover and a battery. The center of the fire prevention layer is provided with the skeleton layer.The skeleton layer is a metal wire mesh layer or a metal sheet layer. Theheat insulation layer is arranged on the skeleton layer. The impact-resistant layer is arranged below the skeleton layer. The heat insulation layer and the impact-resistant layer are bonded and fixedwith the skeleton layer through the adhesive.The battery surface is covered with the fire prevention layer, and the fire prevention layer is arranged between the battery system box cover and the battery. After adopting the technical scheme, the beneficial effects are that the structural design is reasonable, the fire prevention layer has the advantages of high temperature prevention, heat insulation, impact resistance and the like, the battery surface is covered with the fire prevention layer with the composite structure structure, the fire prevention layer can effectively separate the firewhen the battery is out of control in heat and thus the fire prevention function can be effectively realized and promotion is easy.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a fireproof layer of a composite structure and a battery system using the fireproof layer. Background technique [0002] In some fires where the combustibles themselves have the three elements of combustion (sufficient fuel, sufficient oxygen generated by themselves, and sufficient heat generated by themselves), it is very difficult to control the fire and extinguish the fire. When a typical fire occurs in a ternary lithium-ion battery used in a new energy electric vehicle, the high energy and the three elements of self-combustion will result in a temperature ≥ 300°C, and the fire will erupt, with a certain impact, and at the same time The rapid dissipation of heat will lead to rapid thermal runaway of adjacent batteries, that is, ternary lithium-ion batteries have three characteristics: high temperature, certain impact force, and rapid heat transfer. The current mainstream fi...
