➀ Scientists at UNSW Sydney have developed a hydrogen-ion battery using tetraamino-benzoquinone (TABQ) as an anode material, offering a sustainable alternative to lithium-ion batteries. The battery operates efficiently even at sub-zero temperatures and has a lifespan of 3,500 charge-discharge cycles. ➁ The technology is particularly suited for renewable energy storage and could enable more efficient hydrogen transportation. ➂ While the production cost is currently high, the use of abundant light elements suggests scalability and affordability in the future.
