500KWh 1MWh High Voltage Rack Mounted Battery Solar Battery System Solution

1. Internal Short Circuit:
Dendrites accumulate at the negative electrode, piercing the separator and causing an internal short circuit.

2. High Current Generation:
External and internal short circuits can generate excessive currents of several hundred amperes.

3. Where Does the Gas Originate?
The organic electrolyte undergoes electrolysis under high current and high temperature conditions, generating gas that increases internal pressure and can even rupture the battery casing.

4. How Does Combustion Occur?
When the gas ruptures the battery casing, it comes into direct contact with air, causing combustion and igniting the electrolyte, generating intense flames, rapid gas expansion, and explosion.

5. Are There Safety Issues with Polymer Batteries?
The electrolyte in polymer batteries is gel-like and semi-solid, making it less susceptible to leakage and resulting in more intense combustion.
