The dangers of lithium batteries are mainly reflected in the following aspects:

1. Overcharge and over discharge: If a lithium battery exceeds its design capacity when charged, or is completely discharged during use, it may cause damage to the battery structure and unstable chemical reactions inside the battery . This may cause dangerous situations such as battery overheating, fire or explosion.
2. Physical damage: When lithium batteries are subjected to physical impact, pressure or extrusion, the internal structure of the battery may rupture, causing battery leakage, fire or explosion.
3. Improper storage and handling: If lithium batteries are exposed to high temperatures for a long time, or are stored or handled under inappropriate conditions, they may also cause spontaneous combustion or explosion of the battery.

In order to reduce the risks of lithium batteries, people need to follow the following suggestions:

1. Use original batteries and chargers: Choose regular brands of lithium batteries and chargers to ensure the products meet safety standards and avoid using low-quality or counterfeit products.
2. Avoid overcharging and discharging: When using electronic devices, try to avoid completely discharging or overcharging lithium batteries to maintain the normal working condition of the battery.
3. Avoid physical damage: Try to avoid physical impact, pressure or extrusion on lithium batteries to prevent rupture of the battery structure.
4. Proper Storage and Handling: When storing lithium batteries, avoid exposure to high temperatures and place them in a well-ventilated, dry and dark place. When disposing of used lithium batteries, they should be recycled and processed in accordance with relevant regulations.

In short, lithium batteries are relatively safe energy storage devices when used normally and properly managed. But to ensure the safety of individuals and the environment, we should follow correct usage and handling methods to reduce potential risks
