5,000 cycle lifespan zinc batteries possible with new breakthrough

Researchers from the University of Technology Sydney and the University of Manchester have developed a zinc-ion battery with a significantly extended lifespan, capable of over 5,000 charge-discharge cycles—about 50% more than current versions. This breakthrough addresses a major limitation of zinc-ion batteries, which traditionally degrade quickly due to internal component wear during repeated cycling. The innovation hinges on two key advances: the creation of a 2-dimensional superlattice material composed of manganese oxide and graphene layers, and the exploitation of the cooperative Jahn-Teller effect, a quantum phenomenon that allows atomic-level stress relief. Together, these innovations prevent the cathode from deteriorating, enabling longer battery life and improved durability. Beyond longevity, the new zinc-ion battery offers several advantages over lithium-ion technology. It is safer, as zinc-ion batteries do not pose the same fire risks as lithium-ion cells, and it is more environmentally friendly, using water-based, low-temperature, and non-toxic manufacturing processes. Additionally, zinc is abundant and
