Severe Ni dissolution and the resulting impedance rise for single-crystal LiNi0.8Co0.1Mn0.1O2 cathode is main challenge greatly hindering its industrial applications. Herein, we propose a novel concept of anchoring interfacial nickel cations on through controllable electron transfer. This strategy realized by applying an ultrathin PMMA surface layer. Different from traditional physical coatings, transfer Ni2+ to ester group confirmed, which contributes effectively inhibits into organic...
Constructing a robust and elastic solid electrolyte interphase (SEI) on graphite anode is an important strategy to suppress lithium-inventory loss prolong the lifespan of state-of-the-art lithium-ion batteries.
In this paper, 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) is adopted as a bifunctional electrolyte additive, which identified to effectively stabilize the surface for both graphite anode and LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode within graphite/NCM523 full cell. The overall electrochemical performances of cell are significantly enhanced with 3 wt % TTE additive in conventional organic electrolyte. A combination studies scanning electronic microscopy (SEM), transmission...
Silicon/graphite composite anodes have drawn extensive attention in the field of power Li-ion batteries for application electric vehicles because their much higher capacity than that traditional graphite anodes. In this work, ethylene sulfate (1,3,2-dioxathiolane-2,2-dioxide, DTD) is investigated as an electrolyte additive to improve Li-storage performance silicon/graphite anode. The electrochemical behavior anode including cyclic voltammogram, discharge/charge at various current density and...
The regulation of solid electrolyte interface (SEI) on electrode material surface is one the most crucial fundamental issues in lithium ion batteries. A desired SEI film characterized by high homogeneity, flexibility and ductility, which able to stand up with volume change active during repeated electrochemical cycles. More than 10% graphite particle easy cause brittle fracture rearrangement film, resulting continuous consumption Li capacity decline cell. Herein, we proposed an situ...
