3D porous spheroidal Na4Mn0.9Ce0.1V(PO4)3@CeO2/C cathode for high-energy Na ion batteries

“…CPE represents the constant phase angle element. The values of R s and R CT calculated by the ZView soware are listed in Table S8, † and D Na + was calculated from eqn (1), 63 as follows:…”

Preparation of nanorod-assembled CNT-embedded LiMnPO4 hollow microspheres for enhanced electrochemical performance of lithium-ion batteries

“…Additionally, carbon materials with various morphologies, when embedded in microclusters, provide electron transport pathways and improve the electrochemical properties, which has been proved by many previous works. [44][45][46][47][48] The morphology and structure of the LiMnPO 4 /CNTs hollow microspheres were further characterized by TEM and HRTEM, as shown in Fig. 4.…”

Preparation of neodymium‐doped LiMnPO 4 /C cathode by sol‐gel method with excellent electrochemical performance for lithium‐ion batteries

“…Generally, the cathode material as a crucial component directly influences the energy/power densities, structural stability, and cost of lithium‐ion batteries. Compared with different structures widely researched cathode materials, including layered structure LiCoO 2 , olivine structure LiFePO 4 , and ternary cathode materials, polyanionic‐based LiMnPO 4 material is a potential cathode material in the aspects of high specific energy density (700 Wh/kg), good structural stability, high operating voltage platform (4.1 V vs Li/Li + ), superior safety, low price, and environmental friendliness, and meanwhile LiMnPO 4 is compatible with the electrochemical stability window of the existing organic carbonate electrolytes system 5‐7 . However, the own structural restriction of LiMnPO 4 leads to obviously intrinsic sluggish electronic/ionic conductivity, Jahn‐Teller effect of Mn 3+ , and thus results in poor electrochemical performance, which greatly limits the further scale production 8,9 .…”
