Abstract
Official abstract text for this publication.
The present disclose provides a lithium-ion battery with a gas-releasing and explosion-proof safety valve, which comprises a casing and a battery core. The casing includes an opening that is sealed by a thermal cover, on which a safety valve is disposed. The safety valve comprises a safety cover and a pressure filter. A middle portion of the safety cover includes a through hole. The pressure filter is affixed to the middle portion of the safety cover and has numerous pores. The safety cover and thermal cover are hooked together. The present invention offers multiple advantages. Firstly, simplified structure without aging issue enhances the safety and reliability of the battery. Secondly, during operation, gas is ventilated when an internal pressure of the battery reaches a certain threshold value to avoid rupture of the battery casing. Thirdly, with enhanced performance of the battery, the cycle life of the battery is greatly increased.
