Recent Progress of Novel Non-Carbon Anode Materials for Potassium-Ion Battery

Rapid development of renewable energy sources has boosted the growth of smart grid system which requires high-energy and cost-effective batteries apart from lithium-ion battery (LIB). With the advantages of widespread availability and low cost of potassium sources, potassium ion battery (PIB) that exhibits similar mechanism to LIB has attracted extensive attention in recent years. Nowadays, non-carbon anode materials for PIB are in the center of spotlight and great achievements have been obtained. To facilitate the development of non-carbon anode materials and the performance improvement of PIB on commercial scale, it is of great importance to deeply understand the assets, liabilities and potassium storage mechanism of these materials. In this review article, the state-of-the-art progress and challenges of novel non-carbon anode materials, including transition metal element -based, IV/V A-group element-based and other materials, have been summarized and discussed, and some mitigation strategies and future research directions have also been proposed.
