Are Rechargeable Batteries Storing Up Trouble?

The UK is seeing an emergence of battery storage systems to power the likes of homes and offices, reducing the reliance on fossil fuels and conventionally generated electricity. Lithium batteries are becoming an integral part of all our lives. These lightweight rechargeable cells are also the choice to power everyday electronic equipment from smart watches to phones, scooters to cars.. They have replaced single use batteries and have become a more convenient and sustainable power source.

But what are the possible downsides of something that we now take for granted?

Despite their eco benefits Lithium-ion batteries can present an increased fire risk that has been highly documented in the media - self-igniting phones, power banks not being able to be stowed in the holds of planes, to the ban of electric scooters on the London underground system.

As with many products there are both advantages and disadvantages in relation to the use and management of Lithium-ion batteries.

The Risk of Fire

The London Fire Brigade have reported that in London alone they attend an average of twenty four fire each week caused by chargers, batteries and cables. Whilst lithium batteries are generally stable, they are sensitive to the way in which they are manufactured, stored and used, and given their high energy density, battery failure can often be catastrophic.

Lithium battery failures or ignites can be caused incorrect charging, mechanical/physical damage (there is a real risk of fires resulting from mechanical damage to batteries left in recycling waste), a manufacturing fault or being charged or stored above or below the temperature recommended by the manufacturer.

Simple ways to mitigate the risks associated with lithium batteries include

Only buying from reputable manufacturers or suppliers.
Register lithium battery powered devices with the manufacturer or supplier to be made aware of product recalls.
Always use the correct charger. Just because another charger has the same plug does not mean it will charge the battery correctly.
If replacing a battery with “after-market” products, ensure that they are compatible with the appliance and the charger.
Follow manufacturers’ recommendations with regard to temperature and storage.
Do not use batteries which have been subjected to physical damage, and that are swollen or deformed.
Dispose of used batteries responsibly.
