The degradation mechanism of Ni-rich cathode material after storing in the ambient air is comprehensively investigated. A facile method for regenerating degraded NCA storage proposed.
Nb-Doped LiNi<sub>0.4</sub>Co<sub>0.2</sub>Mn<sub>0.2</sub>O<sub>2</sub> nanobelts have been fabricated by an electrospinning method and used in lithium-ion batteries, which exhibit superior electrochemical performances. It is highly expected that this facile may lead to further developments for other 1D multi-element oxide systems.
Free-standing Li<sub>1.2</sub>Mn<sub>0.54</sub>Ni<sub>0.13</sub>Co<sub>0.13</sub>O<sub>2</sub>/MWCNT (LLO/MWCNT) framework electrodes have been successfully fabricated for high energy density lithium-ion batteries. By constructing a 3D conductive network, the LLO/MWCNT cells exhibit superior electrochemical performances.
C,N-LiFePO4 mesocrystals were successfully prepared through topotactic conversion of ferric giniite using an ionic liquid as a carbon and nitrogen source, which provided pathway for rapid electron transfer shortened the Li+ diffusion distances. Thus, good cycling stability rate capability are achieved, showing improvement strategy mesocrystalline electrodes coated with N-doped from liquid.
Layered lithium-rich manganese oxide (LLO) cathode materials have attracted much attention for the development of high-performance lithium-ion batteries. However, they suffered seriously from disadvantages, such as large irreversible capacity loss during first cycle, discharge decaying, and poor rate performance. Here, a novel method was developed to coat surface 0.4Li2MnO3∙0.6LiNi1/3Co1/3Mn1/3O2 material with reduced graphene-oxide (rGO) in order address these drawbacks, where surfactant...
