Which devices take lithium-ion batteries?

As we move through our daily lives, lithium-ion batteries silently power many devices that keep us connected, moving, entertained, and productive. From smart watches to e-bikes, these rechargeable energy sources can be used for a wide variety of practical applications. But they also come with unique fire risks, so it’s important to know exactly where they may be in order to prevent lithium-ion battery fires. 

Before we dive into the hazards, it’s helpful to look at devices – exactly what has lithium-ion batteries inside? Here, we cover the wide range of items containing this rechargeable energy source, and answer some FAQs regarding them.

Are rechargeable batteries lithium-ion?

The widespread application of lithium-ion lies in its ability to be recharged again and again. So yes, this makes them the perfect choice for rechargeable batteries. Unlike lithium batteries, which cannot be reused once depleted, lithium-ion batteries operate through a reversible electrochemical process – perfect for charging up and using for long periods of time without electricity. 

Which everyday devices contain lithium-ion?

Most people in the UK have a mobile phone, and plenty have a smart watch on their wrist. Adults and children alike own tablets, laptops, and digital cameras, while the DIY-savvy own personal power tools such as cordless drills. All these devices require lithium-ion batteries to run long term, and store plenty of electrical power without depleting. So, let’s look more closely at the most popular applications.

Are phone batteries lithium-ion?

Yes, lithium-ion batteries are the power source that allows smartphones to remain mobile for long periods of time and be charged quickly over and over again. They’re lighter than most types of battery, too, which makes them easier to carry around in our pockets.

Are laptop batteries lithium-ion?

For the same reasons as smartphones, lithium-ion batteries are also used in rechargeable laptop batteries. But are all laptop batteries lithium-ion? The vast majority are, but the type of batteries used can vary depending on model, brand, and budget – checking the label on a laptop or smart tablet battery, or the user manual, will typically indicate what’s used. 

Do smartwatches use lithium-ion?

Since lithium-ion batteries are small, have a low-drain durability, and a long life span, they’re ideal for smartwatches, fitness trackers, and other wearable technology – even pacemakers.

Do portable power packs use lithium-ion?

Anyone who has taken a portable charger on holiday may know that airlines have specific rules for travelling with these power packs. This is because they use lithium-ion batteries, which are classified as ‘dangerous goods’ and subject to international regulations.

Which vehicles are lithium-ion batteries used in?

The transport industry relies heavily on lithium-ion batteries, which contribute to more energy-efficient vehicles. From caravans to canal boats to aeroplanes, lithium-ion batteries can be used for auxiliary power units and other applications. The rise of electric vehicles has also been fueled by lithium-ion – let’s take a closer look…

Are lithium-ion batteries used in electric cars and buses? 

Yes and yes. Most modern all-electric vehicles are powered by lithium-ion batteries, as well as the charging stations themselves, though the chemistry often differs from that of day-to-day consumer electronic batteries. 

Do e-bikes and e-scooters contain lithium-ion?

Mobility scooters, electric wheelchairs, and even golf carts rely on rechargeable lithium-ion batteries, and the popularity of e-scooters and e-bikes (both containing lithium-ion batteries) has led to a surge of fires caused by exploding lithium-ion batteries – in 2023, London Fire Brigade were called to an e-bike or e-scooter fire once every two days on average.

Preventing lithium-ion battery fires in different settings

While the majority of lithium-ion batteries are safe, these popular power sources have been linked to a growing number of fire incidents. And with such widespread use in a variety of industries, those responsible for fire safety are wise to mitigate the specific explosive risks of these devices. 

Whether protecting smart devices in schools and mobile/laptop repair stores, back-up power systems in hospitality settings, or larger e-bike and energy storage facilities, it’s crucial to stay aware and updated of the dangers associated with lithium-ion batteries and take precautions to ensure their safe usage.
