Lithium-ion (Li-ion) batteries are widely used in modern electronics, electric vehicles, and portable tools. Unlike traditional batteries, lithium-ion cells use lithium compounds as the active material in both the anode and cathode, allowing for efficient energy transfer and compact construction.

Their ability to store large amounts of energy in a small form factor makes them ideal for portable applications. Additionally, they exhibit low self-discharge rates and no memory effect, meaning they retain charge well and do not require full discharge before recharging.

However, lithium-ion batteries also present safety challenges. If damaged, improperly charged, or exposed to extreme temperatures, they can become unstable, leading to thermal runaway—a condition that may result in fire or explosion. This risk is particularly relevant in workplace settings where multiple batteries are used and charged simultaneously.

To mitigate these hazards, proper handling, storage, and disposal practices are essential. Risk assessments, fire protection systems, and the use of certified charging equipment can significantly reduce the likelihood of incidents.

As their use continues to grow, understanding the characteristics and risks of lithium-ion batteries is crucial for ensuring both operational efficiency and safety.

Aviva Insurance has produced a Loss Prevention Standard, which discusses some of the main concerns and provides general guidance that can help reduce the potential for significant loss and consequences to business trading and it covers a range of topics including:

• Understanding the Risks

• General Considerations

• Storage and Charging Locations

• Segregation

• Proprietary Storage/Charging Cabinets

• Other Cabinets

• Storeroom

• Contractors Equipment

• Damaged or Faulty Batteries

• End-of-Life Battery Management
