英文摘要: Abstract(#br)1D porous ZnCo 2 O 4 cuboids tailored by green natural soybean oil (SZCO) were harvested by a facile micro-emulsion strategy and were used as anodes for lithium ion batteries (LIBs). The as-prepared ZnCo 2 O 4 particles in a length range of 20–50 μm are characterized by 1D porous cuboid architecture and large specific surface area, exhibiting a high initial coulombic efficiency of 80.6%, good cycling durability and considerable specific capacity of 1029.3 mA h g −1 at 1000 mA g −1 even after 400 cycles. Furthermore, the electrode owns superior rate capability such as 1309.8, 1190.5, 954.9 and 724.4 mA h g −1 at current densities of 500, 1000, 2000, and 4000 mA g −1 , respectively. The achieved electrochemical properties are ascribed to the favourable morphology, which...
