Preventing Lithium-Ion Battery Fires
Lithium-ion batteries power many devices in our daily lives including laptops, smartphones, and electric vehicles such as e-bikes and e-scooters. While these batteries are generally safe when properly maintained, they can pose serious safety risks if damaged or improperly handled. Lithium-ion batteries can present fire hazards if they experience:
- Dents, cracks, or damage to battery casings from being dropped, crushed, or punctured
- Exposure to water and/or extreme temperatures
- Overcharging
- Degradation due to advanced age
- Improper disposal
Safety recommendations:
- Review the E-Bikes and E-Scooters policy and remember to never store or use these vehicles indoors.
- For safe charging, use only appropriate chargers designed for your specific device, avoid charging beyond recommended times, and monitor for excessive heat.
- Keep your devices protected from extreme temperatures, water exposure, and physical damage.
- Maintain your devices by replacing old batteries according to manufacturer guidelines, using only reputable products, and discontinuing use if you notice any concerning changes like swelling, leakage, heat, or odors.
- When disposing of lithium-ion batteries, use designated recycling channels. For more information on battery recycling at the University of Rochester, visit the Green Office Guide.
