【 摘 要 】

Lithium-ion batteries are currently the most promising storage device. An electronic conductivity is a key factor that affects the performance of Lithium-ion batteries (LiB). In this work, LiNiSixP1-xO4/C, (x = 0.00, 0.05, 0.10, 0.15, and 0.20) as cathode materials were effectively synthesized by a solid-state reaction technique. To enhance the ionic conductivity of Lithium-Ion Battery application, we used sucrose as a carbon source and Si ion as a dopant in LiNiPO4 cathode material. The effect of Si dopant on its crystal structure, composition, and functional groups existing in cathode material LiNiSixP1-xO4/C are investigated analytically. The samples were characterized by using the X-ray Diffractometer (XRD), X-Ray fluorescence (XRF), and Fourier Transform Infrared Spectroscopy (FTIR). The different amount of Si dopant promotes the structural modification and important role to improve the rate performance of LiB.
