Abstract
The present invention relates to a double explosion-proof filter structure for preventing explosions in lead-acid batteries, and more specifically, to a double explosion-proof filter structure for preventing explosions in lead-acid batteries that provides a double explosion-proof filter structure to reduce the risk of explosion and fire that may occur in lead-acid batteries. According to the present invention, by introducing a double explosion-proof filter structure, a physical space is created between the first explosion-proof filter and the second explosion-proof filter so that they can operate independently, and the first explosion-proof filter is coated with a porous PTFE film so that gas passes through but liquid is blocked. As a result, even if the filter becomes wet due to electrolyte leakage, gas discharge is not blocked and can be safely carried out.
