Researchers from China have created a new kind of battery that holds twice as much energy as regular lithium-ion batteries. This means it can power electric vehicles better and safer.
These new batteries are different because they use water instead of other chemicals. This makes them much safer because they are less likely to catch fire.
These special batteries, which use iodide and bromide ions, have been tested thoroughly and have shown they can last for a long time – up to 1,000 times they can be used and recharged.
These water-based batteries are also expected to cost about the same as regular lithium batteries. This makes them a good option for storing large amounts of energy for things like powering entire cities or electric vehicles. This discovery is a big deal in the world of batteries and could change how we use energy in the future.
