Lithium-ion Batteries are the most popular in the battery industry. However, they have inherent safety problems because of their structure and materials.
Due to the high voltage total and the large working current needed in the power sector, thousands of batteries are often used in groups. The safety of batteries is an issue that has become more important at this point. The safety problem hasn’t been fully resolved as far as battery material technology goes. Heat insulation, flame retardant, and fire protection are all effective methods to reduce harm caused by lithium-ion battery thermal runaway.
Aerogels currently have the lowest known thermal conductivity among solid materials. Aerogel insulation materials, heat-insulation panels, and heat-insulation papers have a thermal insulation performance that is up to five times greater than other products. These materials also offer excellent fire retardancy and flame resistance. With the growth of the aerogel sector, applications of aerogel to batteries are becoming more widespread. They offer soft impact resistance and noise reduction in addition, as well as good promotion for industrial energy savings, civil insulation etc.
Aerogel has a very low thermal conductivity
Researchers have tested the thermal insulation effect of heat insulation boards between single cells. The thermal runaway experiment was used to test the aerogel separator. A 6Ah battery module was placed in a 20mm-spacing module, with four insulation materials of 200mm and a board of 1cm thickness between two monomers. Thermal runaway is blocked in the thermal protection compartment of a single cell.
The results from the experiments show that when monomer A becomes thermally out-of-control, monomer in the blank groups without thermal protection quickly becomes heated and thermally in control. In contrast, experimental monomer with an aerogel between the monomers reaches only 110°C. It successfully blocks the thermal spread of a 6Ah battery cell at 20mm.
Due to its excellent properties of heat insulation and flame retardance, aerogel is able to further reduce the safe distance between monomers. Aerogel companies have created a range of ultra-thin aerogel sheets, insulation paper, and other products that are designed to maximize the total power in the battery pack and reduce the space required.
Aerogel will be used more widely in battery applications as my country develops its aerogel industry. This will include the latest military thermal batteries and more civilian applications, including new energy power battery, Thermal insulation, and flame retardant protection of lithium-ion and accumulator batteries in electronic equipment.
