How to make batteries last longer and what causes them to EXPLODE

How to make batteries last longer and what causes them to EXPLODE

Smartphone technology is always marching forward, progressing rapidly with new hardware improvements with each iteration and model revision. Faster processors, fingerprint sensor, better cameras, waterproofing - the list goes on.

However, there's one essential hardware component that seems to be lagging behind - the battery. We are still waiting for that big technology breakthrough that will revolutionize how we go about charging (and discharging) our smartphones. For now, we are stuck with the current standard of batteries - lithium-ion.

So how do we make the most out of this current battery technology?

A video from the American Chemical Society looks to answer these questions.

Avoid heat

According to the video, due to how a lithium-ion battery's cathode, electrolyte and anode chemical reactions work, it's vital that users avoid heat as much as possible.

Never leave your phone in a hot car or under the sun because the heat speeds up the chemical reactions that make batteries lose their capacity. These reactions break down the electrolyte and reduce the number of accumulation of lithium ions on the anode, meaning the battery will have less capacity every time it's exposed to higher temperatures.

Heat can also cause a process they call "thermal runaway." In this condition, if the cathode gets hot enough, it starts a cycle of reactions that will produce even more heat. If the heat is sufficient enough to boil the liquid electrolyte in the battery, it will build up internal pressure until it finally explodes.

Don't let your phone drain down to zero

To make your smartphone's lithium-ion battery last longer, ACS's chemists suggest not to drain it down completely.
