Dual-ion battery prototype promises safe and cost-competive energy storage
Scientists have fabricated a working battery using a new type of dual-ion chemistry. The design avoids many of the rare or expensive materials found in today’s lithium-ion batteries, and also comes with an inherently lower risk of fire. The battery showed promising performance, and its creators say they have identified several areas where performance could potentially be improved.
