Abstract

The conventional method for fabricating lithium-ion battery (LIB) electrodes heavily relies on the wet coating process, which involves the use of the environmentally harmful and toxic solvent N-methyl-2-pyrrolidone (NMP). Apart from being unsustainable, this costly organic solvent significantly inflates the production expenses of batteries due to the need for drying and recycling throughout the manufacturing process. In this report, we introduce a commercially viable and environmentally sustainable dry process technique. This method utilizes a (polytetrafluoroethylene)PTFE as a dry powder. We successfully synthesize LiNi0.6Co0.2Mn0.2O2 and graphite electrodes by dry-processing using the fiberization of polytetrafluoroethylene. The produced electrodes exhibit a porous structure, and uniform dispersion of polytetrafluoroethylene was confirmed through F. The structural/electrochemical stability is observed at the driving voltage of the electrodes. The initial charge-discharge and cyclic voltammetry are measured and analyzed to evaluate the electrochemical performances. As a result, we could conclude that the synthesized electrodes could be sufficiently applicable to next-generation energy storage devices.
