Soc. 168 040531 DOI 10.1149/1945-7111/abf7e8 Increasing the Ni content of a Ni-rich layered positive electrode material is one common way to improve energy density of Li-ion cells but normally leads to shorter cell lifetimes. Single crystalline materials have been shown to improve the cell lifetime by reducing the degree of material degradation.
For the preparation of materials for lithium-ion battery cathodes, the solid phase sintering method, which has the following process flow: sol-gel, drying, impregnation, sintering, and curing, is the best available. The pH of the solution sample was changed to 7–8 by Nilüfer et al. using sucrose as a novel, affordable polymerizing agent.

The sol-gel approach calls for quickly combining the sol and gel at room temperature to create a gel layer that is insoluble in water and has a specific viscosity, and then preparing the materials for lithium-ion battery cathodes through drying, sintering, curing, or chemical means .
NiO 6, CoO 6, and MnO 6 share a corner in the 001 plane, these layers are perpendicular to the c-axis. The “001” planes are not electrochemically active because they do not offer a sufficient route for Li + ion migration. The electrochemical characteristics of NCM nanostructures with active planes of 010 can be restored.

The positive electrode material usually contains a polyvinylidene (PVDF)-based binder, which needs to be removed by heat treatment or dissolution before the direct repair process. The solvothermal separation of the cathode material and current collector is achieved by dissolving the PVDF-based binder in organic solvents. The solubility of PVDF in N …
