Gadolium-doped spinel LiGdxMn2-xO4 (x = 0, 0.02, 0.04, 0.08) was synthesized by a sol-gel method. The Gd content strongly affected the dependence of initial capacity and retention of LiGdxMn2-xO4 on C-rate. While the greatest initial capacity of undoped LiMn2O4.

The structural characteristics of terbium-doped spinel LiTbxMn2–xO4 related to the electrochemical performance were studied as the cathode in lithium-ion batteries. We chose terbium as the dopant, which is a well-known mixed-valent cation (3+/4+), expecting that it would provide structural stabilization and improve the power density.
