Researchers at the University of California, Los Angeles (UCLA) have developed a 3D-printed zinc battery that stores seven times more energy than conventional zinc batteries, according to a study published in a peer-reviewed journal. The battery retains 82% of its capacity after 1,500 charge-discharge cycles, the researchers reported.
The advance addresses long-standing limitations in zinc battery technology, which has been considered a safer and more sustainable alternative to lithium-ion chemistries but has struggled with performance, officials said.
