Introduction With increasing concerns on energy shortage and environmental issues from fossil fuels, the demand for green and sustainable energy sources is urgent .
Thus, an ideal cathode in a Li-ion battery should be composed of a solid host material containing a network structure that promotes the intercalation/de-intercalation of Li + ions. However, major problem with early lithium metal-based batteries was the deposition and build-up of surface lithium on the anode to form dendrites.
The escalating incidence of fires and explosions in lithium-ion batteries has heightened concerns regarding battery safety . The most destructive failure mode of a battery is thermal runaway, which can swiftly elevate the temperature to 500–1000 °C within a brief period.
These materials have both good chemical stability and mechanical stability. 349 In particular, these materials have the potential to prevent dendrite growth, which is a major problem with some traditional liquid electrolyte-based Li-ion batteries.
