Magnesium ion batteries(MIBs)are a potential field for the energy storage of the future but are restricted by insufficient rate capability and rapid capacity degradation.Magnesium-sodium hybrid ion batteries(MSHBs)are an effective way to address these problems.Here,we report a new type of MSHBs that use layered sodium vanadate((Na,Mn)V8O20·5H2O,Mn-NVO)cathodes coupled with an organic 3,4,9,10-perylenetetracarboxylic diimide(PTCDI)anode in Mg2+/Na+hybrid electrolytes.During electro-chemical cycling,Mg2+and Na+co-participate in the cathode reactions,and the introduction of Na+pro-motes the structural stability of the Mn-NVO cathode,as cleared by several ex-situ characterizations.Consequently,the Mn-NVO cathode presents great specific capacity(249.9 mA h g-1 at 300 mA g-1)and cycling(1500 cycles at 1500 mA g-1)in the Mg2+/Na+hybrid electrolytes.Besides,full battery dis-plays long lifespan with 10,000 cycles at 1000 mA g-1.The rate performance and cycling stability of MSHBs have been improved by an economical and scalable method,and the mechanism for these improvements is discussed.
