Structural and electrochemical study of Cr-substituted layered manganese oxide cathode materials

Synthesis and electrochemical properties of monoclinic fluorine-doped lithium manganese oxide (LixMnO2−yFy) for lithium secondary batteries

“…9 Cation doping protects the layered monoclinic structure against Jahn-Teller distortion 10 and has superior Li insertion/ extraction cycling properties for m-LiMnO 2 . Many studies have focused on stabilization of the layered material structure, particularly for m-LiMnO 2 , by partial substitution of Mn by Cr, Al, Co, Ni and Mg. [11][12][13][14][15][16][17][18] However, for m-LiMnO 2 to be suitable for practical applications such as high-energy and power density applications, further stabilization of the monoclinic structure is needed. Small amounts of additional dopants such as uorine 19 into the Li(Ni 1/3 Co 1/3 Mn 1/3 )O 2 lattice have been reported to improve the structural stability and enhance the cycling performance.…”

One-step synthesis and electrochemical behavior of LiMnO2 and its composite from MnO2 in the presence of glucose

“…As an important cathode material [6,7], lithium manganese oxide has been widely studied for its low cost, non-toxicity and abundant of Mn source. The Li-Mn-O compounds can present different stoichiometries, such as LiMnO 2 and Li 2 MnO 3 , etc.…”
