Scientists in Moscow have developed a titanium-based electrode material for metal-ion batteries they claim challenges the perceived wisdom of the element’s cathode potential and which could give researchers a ‘playground’ for the design of sustainable, cost-effective, titanium-based electrodes.
Scientists in China claim to have identified a special cathode material that could be utilized in more stable potassium-ion storage systems. According to the group, this new material could enable the development of storage systems able to retain 94% of their capacity after 2000 cycles, with 0.003% capacity fade per cycle.
Researchers in China have ranked some of the most commonly used battery chemistries according to parameters deemed important for grid-level storage. The team gave a score in each category and determined a winner – and it wasn’t lithium-ion.
Scientists led by Moscow’s Skolkovo Institute of Technology have drawn upon several of their recent battery material innovations to create a potassium-ion device. The institute says its development will pave the way for ultrafast and durable, high capacity metal-ion batteries, to supply rising demand for energy storage innovations.
