Abstract

Electrode drying is a critical but often underemphasized step in lithium-ion battery (LIB) manufacturing because it directly links production throughput with electrode microstructure, adhesion, and electrochemical performance. For commercially important LFP-graphite cells, conventional slow drying remains widely used for process stability, yet it imposes major penalties in energy demand, dryer footprint, residence time and operating cost. This review examines rapid drying strategies for LFP cathodes and graphite anodes by integrating four connected perspectives. The review shows that rapid drying can substantially reduce drying time, energy consumption, and equipment size through approaches such as intensified convective drying, infrared-assisted drying, hybrid infrared-hot-air systems, multistage drying and laser-based drying. However, these gains are not automatic, because excessive drying rates can promote binder migration, component segregation, through-thickness heterogeneity, adhesion loss, cracking, and transport limitations. The review further highlights that graphite anodes and LFP cathodes respond differently to drying severity, making electrode-specific process design essential. The most promising industrial route is not maximum drying speed but controlled drying trajectories that balance throughput with microstructural uniformity and interfacial stability. Future progress will depend on integrating profile-controlled drying, formulation optimization, advanced diagnostics, and standardized techno-economic metrics to evaluate rapid drying beyond drying time alone.
