摘      要：Aqueous alkaline zinc batteries(AZBs)exhibit great potential due to their high capacity,high safety and low ***,despite these advantages,the lack of high stability and high utilization rate makes the search for high-performance cathode materials a great ***,an amorphous nickel boride/rGO(NixB/rG O)complex structure was *** a result of abundant unsaturated active sites and synergistic electronic effects,amorphous NixB exhibits excellent energy storage *** well as having high electrical conductivity,rGO avoids aggregation of NixB nanoparticles,ensuring that NixB/rGO electrodes have a high energy storage *** structure has a strong adhesion between NixB and rGO,which protects its stable structure and extends its *** importantly,the NixB/rGO//Zn full battery shows remarkable capacity(228.4 m Ah/g at 2 A/g),extraordinary cycle durability(93.7%retained after1000 cycles)and strong energy density 399.7 Wh/kg,when coupled with NixB/rGO *** work will also shed light on other nickel-zinc batteries in order to achieve super durability and capacity.
