Dear Faculty Members and Colleagues,

To prevent similar incidents arising from improper lithium battery testing or usage and to ensure the safety of all faculty and students during teaching and research activities, please pay close attention to the following safety guidelines for the use and storage of lithium batteries:

I. Procurement and Usage

1. Select lithium batteries and charging devices certified by recognized safety standards (e.g., BSMI,CE, UL, TUV).
2. Avoid using unverified or self-modified battery modules.
3. Read the manufacturer’s instructions carefully before use and confirm that voltage, current, and other specifications meet the equipment requirements.

II. Charging Safety

1. Charging must be monitored by personnel on site. Do not leave charging batteries unattended for long periods or overnight.
2. Do not charge batteries near high temperatures, moisture, or flammable materials.
3. Use only original or fully compatible chargers to prevent overcharging or over-discharging.

III. Storage and Transportation

1. Store lithium batteries in a cool, dry, and well-ventilated area, avoiding direct sunlight or high temperatures (recommended below 30°C).
2. Keep batteries away from metal objects to prevent short circuits.
3. For long-term storage, maintain 40–60% charge and inspect the battery condition periodically.
4. During transportation, use protective packaging to prevent compression, impact, or dropping.

IV. Handling Abnormal Conditions

1. If a battery shows swelling, leakage, smoke, odor, or abnormal heat, stop using it immediately and place it in a fireproof safety cabinet or move it away from the area.
2. Do not use water to extinguish fires. Use a Class D dry powder extinguisher or fire sand instead.
3. If the battery ruptures or goes into thermal runaway, evacuate immediately to an upwind location.
4. Report to technicians and workplace supervisors for emergency response, guidance, and evacuation procedures.

Please inform all laboratory students and collaborating companies or contractors of the above information and ensure strict compliance. Let us work together to maintain campus safety and prevent lithium battery-related incidents.
