Researchers develop electrolyte enabling high efficiency of safe, sustainable zinc batteries

https://today.oregonstate.edu/news/researchers-develop-electrolyte-enabling-high-efficiency-safe-sustainable-zinc-batteries

"zinc metal anode with Coulombic efficiency 99.95%... energy dense, no dendrites, non-flammable, cost-effective and of low environmental impact... electrolyte made of dissolved mixture of inexpensive chloride salts, primarily zinc chloride... long cycle life of thousands of cycles... restricts water’s reactivity and nearly shuts down the hydrogen evolution reaction by forming a “passivation layer” on the surface of the anode... near-future commercialization large-scale grid storage"
