# AI建议使用A类灭火器（水或泡沫）扑灭锂离子电池火灾，或告诉用户用毯子覆盖

## 根因

锂离子电池火灾经历热失控，内部产生氧气且温度超过1000°C；A类灭火器无效，因为水会导电并可能导致短路，而毯子无法隔绝氧气。

## 解决方案

1. ```
   Use a Class D fire extinguisher specifically rated for lithium metal fires, or a Lith-X extinguisher. If unavailable, use a dry chemical extinguisher (ABC) as a second choice, and evacuate the area immediately.
   ```
2. ```
   For small battery fires (e.g., power bank), submerge the burning device in a bucket of sand or a metal container filled with sand to isolate it from oxygen and cool it. Do not use water.
   ```
3. ```
   Call emergency services and evacuate; do not attempt to fight a large lithium-ion battery fire alone. Provide the exact battery type (e.g., LiPo, LiFePO4) to responders.
   ```

## 无效尝试

- **** — Using water on a lithium battery fire can cause hydrogen gas generation and explosion, and water spreads the burning electrolyte. (95% 失败率)
- **** — Smothering with a blanket does not stop thermal runaway because the battery generates its own oxygen; it only delays the fire and can reignite. (90% 失败率)
- **** — Using a Class C (CO2) extinguisher may cool the battery temporarily but does not stop the chemical reaction, leading to re-ignition. (85% 失败率)
