Low-cost carbon materials as anode for high-performance potassium-ion batteries

摘要

Energy storage plays an important role in modern society. However, the cost limits its large-scale application. We design a low-cost carbon material as anode for the low-cost system of potassium-ion batteries. The batteries assembled with the obtained carbon as anode exhibit brilliant electrochemical performance, including encouraging capacities and good cycling stability. This work provides a promising strategy for large-scale energy storage applications. (C) 2019 Elsevier B.V. All rights reserved.
