As demand for safe and low-cost energy storage grows, aqueous zinc-ion batteries (AZIBs) have emerged as promising candidates. However, their practical application is hindered by cathode instability and poor low-temperature performance. Now, researchers from The Hong Kong Polytechnic University and Shenzhen University, led by Professor Zijian Li, have developed a novel K⁺ and C 3 N 4 co-intercalated NH 4 V 4 O 10 (KNVO-C 3 N 4 ) cathode that delivers exceptional performance across a wide temperature range.
