University of Houston researchers have cracked a puzzle that has stumped battery scientists for decades. They figured out why solid-state batteries die and found a simple fix that could change how we power electric cars and phones. The team used special microscopes to watch what happens inside these batteries while they work. What they saw surprised them. Tiny empty spaces called voids grow inside the battery over time. These spaces merge together and create big gaps that stop the battery from working properly. Think of it like small cracks in a wall that slowly join together until the whole wall … Continue reading Battery Scientists Fix Major EV Problem with Tiny Magnesium Addition
