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.Among the less explored possibilities for overcoming the limitations of today's lithium-ion technology are dual-ion batteries, in which both positive and negatively charged ions are active in energy storage. Such batteries ...Den vollständigen Artikel lesen ...
