Uniform yolk–shell V2O5 microspheres were synthesized via a facile template-free solvothermal route and subsequent calcination treatment in air. The resulting cathode materials showed high specific capacity of 220 mA h g−1 after 30 cycles good rate capability.
Mesoporous interconnected carbon-encapsulated Fe3O4 (Fe3O4@C) nanospheres assembled from tiny nanoparticle subunits have been synthesized by a one-pot solvothermal decomposition route followed thermal annealing. Electrochemical characterization of these Fe3O4@C exhibits capacity 636 mA h g−1 at 0.2–1 C over 50 cycles when employed as anode materials in Li-ion batteries.
Lithium/fluorinated carbon (Li/CFx) primary batteries have essential applications in consumer electronics and medical high-power military devices. However, their application is limited due to the difficulty achieving simultaneous high power density energy CFx cathode. The tradeoff between conductivity fluorine content decisive factor. Herein, by rational design, 3D porous fluorinated graphene microspheres (FGS-x) with both a F/C ratio are successfully synthesized for first time. FGS-x...
Fluorinated carbon (CFx ) is considered as a promising cathode material for lithium/sodium/potassium primary batteries with superior theoretical energy density. However, achieving high and power densities simultaneously remains considerable challenge due to the strong covalency of C-F bond in highly fluorinated CFx . Herein, an efficient surface engineering strategy combining defluorination nitrogen doping enables graphene nanosheets (DFG-N) possess controllable conductive nanolayers...
Self-assembled porous hierarchical-like CoO@C nanoarchitectures have been fabricated on a large scale through facile solution-phase process and subsequent annealing of the inorganic–organic Co(OH)2–DS (dodecyl sulphate) precursor nanocomposites. The as-formed nanohybrid as an anode material for lithium-ion batteries can exhibit not only highly reversible capacity but also excellent cycling performance well good rate capability. Results show that these hierarchical microsheets made...
Sodium and potassium are considered to be the most promising anode candidates due their easy availability, low-cost similar chemical properties lithium. Here, novel 3D accordion-like fluorinated graphite nanosheets (FGNSs) reported as cathodes for sodium primary batteries (SPBs) (PPBs). The FGNSs-x cathode exhibits unprecedented power energy density impressive structure, high F/C ratio (1.0), more surface CC bonds (7.14%). FGNSs-1.0 very specific capacities of 831.3 834.1 mAh g-1 SPBs PPBs,...
Focusing on the failure mechanism of active materials during charging–discharging, mechanical properties Li–Sn alloys are studied by density functional theory, including elastic moduli, Poisson's ratio, anisotropy, and brittleness-ductility.
Abstract Unclear reaction mechanisms and unsatisfactory power performance hinder the further development of advanced lithium/fluorinated carbon (Li/CF x ) batteries. Herein, mechano‐electrochemical coupling behavior a CF cathode is investigated by in situ monitoring strain/stress using digital image correlation (DIC) techniques, electrochemical methods, theoretical equations. The DIC results present distribution dynamic evolution plane strain indicate strong dependence toward material...
