| Abstract: |
| With their excellent safety, affordability, environmental friendliness and high ionic conductivity, aqueous batteries are prospective contenders to replace lithium-ion batteries. However, the pH of aqueous electrolyte might impact the battery's electrochemical performance and even its normal operation. It is critical to develop an electrode that can work in different pH settings. The hydrothermal method and vulcanization treatment were used to successfully create copper sulfide (CuS) nanosheet in this work. It can store and transport nonmetal and metal ions as well as polyvalent ions with a high charge radius ratio, and function normally under a variety of pH conditions. The CuS electrode has a considerable capacity (900 mA·h/g) and rate performance under alkaline conditions, as well as an ultra-long discharge platform, which contribute to 80% of the total capacity. |
