  "textContent": "As the demand for more reliable power systems grows in the renewable energy sector, the race is on to develop batteries that cost less but have a longer lifespan. While zinc-based batteries are safer and more cost-effective than lithium-ion batteries, a major obstacle to their use in large-scale, grid storage is their shorter lifespan. They fail sooner because they develop tiny, tree-shaped metal structures on the anode called dendrites, which cause the battery to short-circuit.",
