文摘The uneven distribution and unrich sources of lithium lead to the high cost of lithium-ion batteries(LIBs),which greatly hinders the further widespread use of LIBs[1].Therefore,it is imperative tofind alternative energy storage systems to replace LIBs.Potassiumion batteries(PIBs)have been demonstrated to display high operating voltages and high energy/power densities due to the low standard redox potential of K^(+)/K and the fast K+diffusion kinetics in the electrolyte caused by the weak Lewis acidity of K^(+)[2–4].Thus,developing high-performance PIBs is very important and highly desirable[5–7].
