A new lithium-ion battery made entirely of solid material has been developed by scientists. It has neither liquids nor gels. The battery is non-flammable, even at very high temperatures, giving it a safety advantage over conventional batteries. Mobile phones, laptops, e-bikes and electric cars are all powered by such batteries.
Conventional lithium-ion batteries are not without their dangers: mobile phone batteries have exploded several times in the past, resulting in injuries, and only 6 months ago an entire row of houses burned down in the old town of Steckborn on Lake Constance...
