Abstract

Olivine-type LiNiPO₄ and their corresponding Nd³⁺ doped LiNiPO₄ cathode materials were synthesized through polyol process with 1, 2 propane-diol as the medium. The inclusion of Nd³⁺ to LiNiPO₄ significantly enhanced the electronic conductivity by two orders as compared to bare LiNiPO₄. The cyclic voltammograms revealed that the rare earth doped LiNiPO₄ electrode improved the electrochemical properties. The single cell consisting of 0.07 mol% Nd³⁺ doped samples showed the highest specific capacity of 95.2 mAh g⁻¹ at low current rate, which makes Nd³⁺ doped LiNiPO₄ a prime candidate for high potential lithium-ion batteries (LIBs).
