Nowadays, my country's new energy automobile industry is developing rapidly, and the state implements multi-faceted policy support for the new energy automobile industry, and new energy automobiles have become a new automobile consumption trend. Lithium batteries, as their sole source of power, currently account for one-third of the total cost of electric vehicles. Therefore, its performance and service life have become one of the key points for consumers.
As an elastic protective material, foamed silica gel is the best material for sealing and buffering protection of lithium battery casings due to its waterproof and flame-retardant properties, high and low temperature resistance, high air tightness, and excellent electrical insulation.
At present, the biggest safety problem of lithium battery is combustion and explosion, and many news reports have also attracted people's attention. Therefore, the waterproof and flame-retardant performance of foamed silica gel has also become the focus of consumers' attention.
Oxygen index and vertical combustion performance are two major indicators to judge its waterproof and flame-retardant performance.
Oxygen index: Under specified conditions, the minimum oxygen concentration required for a material to burn flamingly in an oxygen-nitrogen mixed flow is one of the indicators for judging the flame retardancy of a polymer. Oxygen index < 22 (flammable materials); 22 < oxygen index < 27 (combustible materials); oxygen index > 27 (flammable materials).
Vertical burning performance: Indicates the flame retardant performance of polymers.
Other properties of foamed silica gel can also make new energy vehicle lithium batteries work better.
High and low temperature resistance
Its working temperature: -100β-350β
High air tightness
Prevent the oil and water inside the car from penetrating into the lithium battery
good electrical insulation
Maintain stable working properties even under high pressure
Physiological inertia
The non-toxic and odorless properties make it superior in physiological inertia, so it also has anti-aging properties.
If new energy vehicles want to break through the current bottleneck of lithium battery technology, they must pay attention to the performance of foamed silica gel and reduce the probability of lithium battery safety accidents.
