LiFePO4 draws as much attention as cathode material in lithium-ion batteries. However, it has poor conductivity and a low lithium-ion diffusion coefficient that lower its performance. By reducing the size to nano-scale size will help solve those problems. In studies, LiFePO4 nanowires are far more efficient than spherical nanoparticles in conducting the electricity due to their longer mean free path. Nonetheless, currently, the LiFePO4 nanostructure available in the industry is in the form of spherical nanoparticles only. Thus, this project provides a simple and straight-away process to synthesize LiFePO4 nanowires by coating and calcination to solve the problem. Cellulose plant can also be used as a template to synthesis LiFePO4 nanowires but is not selected because of high cost and not environmental friendly for its purification process. Bacterial cellulose (BC) was used since it gave pure cellulose, which can reduce the cost and environmental effect to synthesis LiFePO4 nanowires. The LiFePO4 nanowires were synthesized by coating the lithium iron phosphate precursor on the BC template aerogel. The nanowires' conductivity then was tested by using RG402 / U semi-rigid coaxial probe filled with PTFE. The effect of B was most significant towards the conductivity followed by factor A, C and interaction of factor AB and BC. The optimized parameters of nanowires were analyzed by using the design of the experiment at the frequency of 2.46GHz. The optimized factors obtained at the condition of 3:1:1 (A), 700�C (B) and 5hours (C) with potential conductivity produced at 4.14972 S/m zainurin UTM 81 p.
