With the popularization of new energy vehicles (NEVs), battery safety has become the core focus of the industry. Liquid silicone rubber (LSR), relying on its excellent protective performance, has emerged as a "safety guardian" in the field of NEV batteries. From battery sealing and insulation to shock absorption, it comprehensively protects the stable operation of batteries, solves many pain points in NEV battery protection, and promotes the high-quality development of the new energy vehicle industry. During the operation of NEVs, batteries are exposed to various challenges such as high temperature, low temperature, vibration, and moisture. Traditional protective materials either have poor temperature resistance or inadequate sealing effect, which are prone to safety hazards such as battery leakage and short circuits. The most prominent advantage of liquid silicone rubber is its excellent high and low temperature resistance and strong sealing performance. It can maintain stable elasticity in the temperature range from tens of degrees below zero to more than 200 degrees Celsius, perfectly adapting to the temperature changes during battery charging and discharging. It will neither deform under high temperature nor become hard and brittle in severe cold weather. It can closely fit every gap of the battery pack, forming a dense protective layer that effectively blocks moisture, dust, and oil from entering the battery interior, prevents battery electrolyte leakage, and avoids short-circuit risks. At the same time, it can resist the corrosion of battery electrolyte and extend the service life of the battery. For example, in the core parts of NEV battery packs such as the shell, pole columns, and liquid injection ports, seals made of liquid silicone rubber can achieve high-standard waterproof and dustproof effects. Even if the vehicle is exposed to rain or wading, the battery safety can be guaranteed. In addition, liquid silicone rubber is soft in texture and excellent in elasticity, with good shock absorption and buffering effects. The vibration generated when new energy vehicles are running is likely to cause loosening and damage of battery components. Liquid silicone rubber can effectively absorb vibration energy, reduce the impact of vibration on the battery, and protect the stable operation of battery components. Meanwhile, it has a pure composition, is non-toxic and tasteless, contains no harmful substances, and does not release volatile organic compounds (VOCs), which meets the environmental protection requirements of new energy vehicles and protects the health of drivers and passengers. From the production perspective, liquid silicone rubber is convenient to process and highly efficient. Before production, it is in a fluid state with excellent fluidity, which can be accurately injected into molds of various complex shapes for battery protection accessories, quickly cured and formed with precise dimensions and a smooth surface, without the need for a lot of post-processing and polishing. Moreover, some self-adhesive models can be directly closely bonded to substrates such as metal and plastic, eliminating the priming process, simplifying the production process, reducing enterprise production costs, and facilitating the large-scale production of new energy vehicles. Today, liquid silicone rubber has been widely used in various NEV battery protection scenarios, becoming the "core barrier" for battery safety. With its multiple advantages of stability, durability, sealing, waterproofing, shock absorption, and insulation, it solves many pain points of traditional materials, not only improving the safety and service life of NEV batteries but also providing strong support for the upgrading and development of the new energy vehicle industry. In the future, as new energy vehicles develop towards high-voltage fast charging and long battery life, liquid silicone rubber will adapt to more high-end battery protection scenarios and continue to guard travel safety.
