In a more perfect world, your mobile phone battery will easily last all day, the power will not degrade over time, and most importantly, it will not explode. This sounds like a dream, but researchers at the University of Maryland have developed a new water and zinc-based battery that can meet all three standards in some way and may eventually appear in future consumer electronics products.
This technical paper developed by the US Army Research Laboratory and the US National Institute of Standards and Technology was published in the journal Natural Resources on Monday. The combination of zinc and water is particularly effective in solving safety issues, such as the problem that caused the Samsung Galaxy Note 7 battery to explode in 2016. According to researchers, the new battery will not be as fire-fighting as the lithium-ion batteries commonly used in mobile phones and laptops. Risks, while surpassing lithium batteries in terms of life.
Zinc batteries are not new. They have been a safe and cheap energy option for a long time, but in the past they were also inhibited by their limited life cycle and low energy density. Wang Fei, a journal article and postdoctoral associate director of the University of Maryland and Army Research Laboratory, said the new "zinc-containing water" battery is the best of both worlds. We have a battery that can compete with lithium-ion batteries in energy density, but there is no danger of explosion or fire. "
The researchers said that their new batteries may eventually be used in consumer electronics. It can also be used in extreme conditions to improve the performance of vehicles used in aerospace, military and deep-sea environments, where explosive batteries can cause catastrophic consequences.
