In heatmaps, the color represents the normalized number of relevant papers. a Relationships between atmosphere and temperature in cathode materials synthesis. b Relationships between salt and solvent in cell assembly. c Relationships between synthesis method and precursor materials in cathode materials synthesis. Here, CVD refers to chemical vapor deposition. d Dependency relationships between precursor materials.
