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.
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.
The tests that were performed on a single battery module were considered relatively comparable to those performed on the battery modules in the battery. The results obtained from the tests were used to make recommendations on how the insulation of the battery can be improved based on applicable automotive standards.
The thermal spreading interval time between the first and second batteries in the battery module was increased to an infinite length, when the composite phase change type thermal insulation layer was used. The zero-spreading effect of thermal runaway in the battery module was achieved.
The following 6 materials are used for the electrical and thermal insulation of batteries and accumulators: 1. Polypropylene film for electrical and thermal insulation of batteries and accumulators Polypropylene has excellent dielectric properties, excellent impermeability, and is easily deformed.
The thermal spread suppression experiment was carried out by using the control variable method, and the influence of different material insulation layers on the thermal spread inhibition performance of lithium-ion battery module was studied.
