A global team of researchers and industry collaborators led by RMIT University has invented recyclable 'water batteries' that won't catch fire or explode.
Lithium-ion energy storage dominates the market due to its technological maturity, but its suitability for large-scale grid energy storage is limited by safety concerns with the volatile materials inside.
Lead researcher Distinguished Professor Tianyi Ma said their batteries were at the cutting edge of an emerging field of aqueous energy storage devices, with breakthroughs that significantly improve the technology's performance and lifespan.
"What we design and manufacture are called aqueous metal-ion batteries -- or we can call them water batteries," said Ma, from RMIT's School of Science.
Such a beautiful dendrite displayed nicely in this piece of Honey Opal self-collected from one of our spots here in Washington State, USA! We are totally LOVING these!!😍💎
According to a study published in Advanced Functional Materials, a research team led by Prof. Hu Linhua from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences found that adding disodium maleate (DMA) to the electrolyte of aqueous zinc-ion batteries would lead to the growth of the preferred Zn (002) texture, which could effectively inhibit the growth of zinc (Zn) dendrite and improve the reversibility and cyclability of batteries.
"This means that the DMA can stop harmful zinc dendrites from growing and improve the ability of batteries to be recharged and used multiple times," said Dr. Li Zhao Qian, a member of the team.
Today, aqueous zinc-ion batteries (AZIBs) have attracted widespread attention for their safety, reliability, and cost-effectiveness. Strong Zn dendrite growth and severe side reactions have become the main obstacles to the widespread commercialization of AZIBs.
neurons and their importance
Neurons are specialized cells that make up the nervous system. They are responsible for transmitting and processing information through electrical and chemical signals in the brain and throughout the body.
The importance of neurons lies in their role in cognitive and physical functions, such as sensory perception, motor control, memory, emotions, and behavior. They…
Wisdom has to be judgmental… Or it’s not. So why is “judgmental” such a curse adjective in the US? Why is wisdom all too often cursed in what is, de facto, the leading democracy?
Indeed, thinking is noble, the most defining human activity. But to think is to judge.
Thinking consists in contemplating one or multiple choices, and then deciding upon one or some of them as true, or optimal, and…
