Understanding in One Reading | From Lab to Production Line: An Analysis of Dry/Wet Pulp Processes for Electrodes

2025-05-28

Battery performance is 70% determined by the electrode slurry. The core objective of the slurry preparation process is to achieve "uniform dispersion of three phases" - with changes in temperature, viscosity, and environment, active materials (energy storage main body, responsible for storing charge, such as lithium iron phosphate in the positive electrode and graphite in the negative electrode), conductive agents (charge pathways, such as carbon nanotubes), and binders (structural support, such as PVDF) form a stable suspension in a solvent (mixed into a slurry, such as NMP), which is finally coated to form an electrode with an ideal porous structure. This article interprets the two major processes of battery slurry preparation: "dry method slurry preparation" and "wet method slurry preparation", understanding the core differences in their principles. Which slurry preparation process is more suitable for your project? How to balance cost and efficiency? Is the technical threshold high? Help you deal with project decisions!
