Engineering a high-capacity and long-cycle life magnesium/lithium hybrid-ion battery using a lamellar SnSe2/SnSe/SnO2 cathode

Since the safety and costs of current lithium-ion batteries are non-ideal, engineering a new energy-storage systems is needed. Magnesium/lithium hybrid-ion batteries (MLHBs) combining fast kinetics of Li ions and a dendrite-free Mg anode are promising. Here, we describe our development of an MLHB using lamellar SnSe
