Sometimes, it does so on the street, but more often, it happens when the owner is recharging the lithium ion battery.

Or, the highly flammable electrolyte inside the battery's cells leaks out of its casing and ignites, setting off a chain reaction.

The head of fast charging at Oppo dreams of a mechanism that fills smartphone batteries in a second. With each new generation of smartphones, manufacturers offer new technologies to increase the autonomy of the devices without (too) enlarging the size of the battery. For example, they may use new processors or new displays with better energy efficiency.

This year, Samsung finally launched its own competitor to the best OLED TVs – the Samsung S95B, which uses a next-gen 'QD-OLED' screen.

Renewables are a promising tool in the fight against climate change, but they have an essential bedfellow. “The only thing that’s holding those resources back from becoming 100 per cent of our total electricity generation is the ability to store that energy and dispatch it as needed,” Matt Harper, co-founder and CCO of Invinity Energy Systems, tells Euronews Green from the US.

 Polar Night Energy's first sand-based thermal energy storage system for commercial use has begun running in Finland. The system installed by Polar Night Energy at the location of a power plant run by utility Vatajankoski has started operating. It is based on its proprietary technology.
