Therefore, the efficient and appropriate thermal insulation material design is crucial for LIB packs to effectively reduce or even inhibit the spread of TR. Based on it, in this review, we present the principle and influences of TR to provide the necessity of battery thermal management and thermal insulating materials.
Lithium-ion batteries generate a significant amount of heat during operation and charging. In addition to using thermal management materials to dissipate heat, using protective, flame-retardant insulation materials between the battery cell, module, and battery components can provide further thermal and electrical insulation protection.
Under external stressors on the battery, the holistic thermal insulation efficacy is compromised, which heightens the susceptibility to TR and affects the energy density and electrochemical safety of the battery.
And the effects of six different materials of thermal insulation layer on the thermal spreading process of lithium-ion battery modules were investigated. The results showed that the use of thermal insulation layers can effectively inhibit the thermal spread in the battery module.
The thermal spreading interval between the thermal runaway battery and the neighboring batteries in the module is increased to an infinite length, and only the thermal runaway battery shows the phenomenon of spraying valve such as fire and smoke. It is expected to have a guidance for the design of thermal insulation in lithium-ion battery modules.
In the context of battery-insulating materials, a deficiency in mechanical strength renders the material susceptible to deformation or damage upon encountering external impacts or extrusion, consequently compromising its thermal insulation efficiency and longevity. Concurrently, heat generation is inherent during battery operation.
