A simple and effective biological Template method was used to prepare porous micro-tubular cobalt oxide by infiltrating cotton fibers with cobalt nitrate solution and then annealing in air at 500 °c. The as-The obtained coprovision has the following features: X-Infrared spectrum (FT-), X-ray diffraction (X-ray diffraction)Infrared (IR), scanning electron microscopy (SEM), N2 adsorption and absorption measurements, and thermal analysis (TG ). According to these results,-The prepared co2o3 has perfect tubular morphology and pore structure. Electrical performance of-The samples obtained were studied as lithium-Cyclic KVA (CV) and charge-anode material for ion batteriesDischarge and electrical impedance spectroscopy (ESI) measurements. Compared with the bulk co2o3 and the previously reported nano-structure co2o3 electrode, the co2o3 electrode in the ordered hole exhibits better lithium storage performance, which can be attributed to its unique morphology, large specific surface area
