Oxygen Ion Battery - A prototype of the battery at TU Wien. Credit: TU Wien Researchers at TU Wien (Vienna) have developed a groundbreaking oxygen-ion battery, which boasts exceptional durability, eliminates the need for rare elements, and solves the problem of fire hazards. Lithium-ion batteries, while commonplace in today’s world – powering everything from electric vehicles to smartphones – aren’t necessarily the optimal solution for all applications. Researchers at TU Wien have made a breakthrough by creating an oxygen-ion battery that offers several significant advantages. While it may not match the energy density of lithium-ion batteries, its storage capacity doesn’t...
