Fast-Charging and Wide-Temperature-Window Ion Battery

The ever-growing renewable energy supplies are spurring the energy community to develop efficient and affordable grid-scale energy storage technologies. Metal-ion batteries, positioned at the forefront of new energy storage technology, facilitate the storage and conversion of renewable energy, offering a robust solution to the energy crisis and environmental degradation caused by the utilization of non-renewable fossil fuels. Presently, the electric vehicle market and mobile portable electronics are imposing increasingly greater expectations on the fast-charging capabilities and wide-temperature window of ion batteries, with the aim of attaining a charging experience akin to refueling within mere minutes even at ultralow -40 ℃. The electrochemical properties of metal-ion batteries largely depend on the anode, cathode and electrolytes etc. As a result, developing fast-charging anode/cathode materials and ultralow-temperature-tolerance electrolyte has become particularly important.

This collection aims to bring the most recent research advancements and authoritative reviews that contributes to fast-charging and wide-temperature-window batteries and refines our understanding of the underlying energy storage mechanisms.
