Yes, they can explode! Lithium-ion batteries can explode due to a chain reaction call thermal runaway. This occurs when the battery rapidly increases in temperature, usually from overcharging, exposure to extreme temperatures or moisture, or damage to the cells. Once thermal runaway begins, it will cause an internal fire in the casing which causes a build-up of toxic gases. The pressure eventually causes an explosive reaction.

Generally, lithium-ion batteries are safe to use and charge regularly, as long as they are not damaged, overcharged, or defective.

Lithium-ion batteries work by moving lithium-ions between the negative side (Anode) and positive side (Cathode), which creates an electrical current. When charging, lithium-ions move from the cathode to the anode and whilst discharging it is opposite. When the lithium-ions move during a discharge, an electrical current is created and this is what powers the device.

Stopping a lithium-ion fire is almost impossible due to the ferocity and unpredictable nature of these types of fires. Instead of stopping a fire, it is recommended that preventative measures are taken to ensure that a fire doesn't start. Fireproof charging and storage cabinets are an ideal solution for ensuring that all lithium-ion batteries can be charged and stored safely, even if a fire broke out. These cabinets are designed to contain the fire inside, preventing it from spreading externally.

General advice from the Fire & Rescue Service is to evacuate and get to a place of safety in the event of a lithium-ion fire. Once at a place of safety, call the emergency services and do not attempt to tackle the fire.

Lithium-ion batteries are rechargeable whereas lithium batteries are not. Lithium batteries are more commonly found in products that require long-term, low-power use such as smoke detectors. Lithium-ion batteries are commonly found in items that require recharging frequently such as mobile phones and laptops. Lithium batteries are made up of pure lithium metal, whereas lithium-ion batteries are made up of active materials, such as lithium cobalt oxide (LiCoO2), and do not contain pure lithium metal.
