Recent developments in electrode materials for dual-ion batteries: Potential alternatives to conventional batteries

Lithium-ion batteries (LIBs), known as “rocking-chair batteries”, have shown a huge success in consumer electronics and energy vehicles. However, the soaring cost caused by the shortage of lithium and cobalt resources as well as the need for ever-higher performance and safety has promoted an urgent need to develop high-efficient battery systems. Dual-ion batteries (DIBs), based on different working mechanism that involves both cations and anions...
