Abstract

Though Li-ion batteries (LIBs) are increasingly utilized in a wide range of applications, their gram capacity is still low and needs to be enlarged. Carbon cladding is an efficient method. The authors in this paper thought of doping Co in the Gram-positive Bacteria Bacillus Subtilis (GPBBS) to clad the Co₃(PO₄)₂, and compounding Reduced Graphene Oxides to form Co₃(PO₄)₂@C/RGO active material, and the prepared coin cell demonstrated extremely a stable performance and could maintain 300 cycles without significant decrease at a current of 100 mA/g, specially it can endure a 1000 mA/g current without an apparent decrease and the discharge capacity at the 600th cycle remained as high as 393.74 mA h/g compared to that at 100 mA/g. The SEM image shows that the material surface is smooth and without any particles, the TEM mapping shows that it has Co, P elements, combining the XRD, Co doped material is Co₃(PO₄)₂ particles, they form a core–shell structure.
