Aqueous zinc-ion batteries have emerged as viable energy storage solutions owing to their economical pricing, enhanced safety features, environmentally sustainable nature, and remarkable theoretical storage capacity. Metal vanadate has been deeply researched as one of the cathode materials with great promise. However, most of the previous reports of metal vanadates require high energy consumption or a complex synthesis process to ensure high electrochemical performance. Herein, Li-K coinsertion vanadate nanoflake (Li-KVO) was synthesized by a facile method at a low-temperature water bath. When...
