K metal holds great promise as the ultimate anode candidate for K-ion batteries because of its high theoretical capacity and low operating potential. However, due to viscosity poor mechanical processability, it remains challenging manufacture potassium anodes with precise parameters by a simple executable method. In this work, high-performance potassium-carbon nanotubes (K@CNTs) composite film electrode three-dimensional (3D) skeleton superior processability is prepared simply incorporating...
LiNi0.8Co0.15Al0.05O2(NCA), a promising ternary cathode material of lithium-ion batteries, has widely attracted attention due to its high energy density and excellent cycling performance. However, the presence residual alkali (LiOH Li2CO3) on surface will accelerate reaction with HF from LiPF6, resulting in structural degradation reduced safety. In this work, we develop new coating material, LiH2PO4, which can effectively optimize NCA remove H2O CO2and form layer ion conductivity. Under...
Due to the assets such as adequate discharge capacity and rational cost, LiNi0.8Co0.15Al0.05O2(NCA), a high-nickel ternary layered oxide, is regarded be favorable cathode contender for lithium-ion batteries. However, superior commercial application restricted by surface residual alkaline lithium salt (LiOH or/and Li2CO3) of nickel-rich materials, which will expedite disintegration structure engendering gas (CO2). Therefore, in this paper, we devise fabricate Y(PO3)3modified intending...
In this paper, via a facile wet coating method, the LaPO4coating layer has been introduced onto LiNi0.87Co0.09Al0.04O2(NCA) surface while small part of La3+has also doped on to realize dual functions modification and doping. The morphology structure samples were investigated by XRD, SEM TEM measurements. chemical compositions analyzed EDS XPS data. results showed that LaPO4and doping La3+were successfully achieved NCA. Electrochemical tests indicate sample modified with 2 wt% LaPO4(L2-NCA)...
