Charged EVs | Video: The advantages and challenges of dry electrode coating expertise for EV batteries


The dry electrode course of is reworking battery manufacturing by eliminating solvents and streamlining manufacturing. Not like the standard moist slurry methodology, the dry electrode coating course of depends on using particular binders that may kind an electrode coating with out being dissolved in a solvent, akin to fluoropolymer binders with Teflonâ„¢ from specialty chemical firm Chemours.

Charged not too long ago chatted with Tejas Upasani, World EV Expertise Supervisor at Chemours to study extra about the advantages and challenges of dry electrode expertise.

One of many key advantages of the dry electrode course of is its optimistic affect on battery efficiency. By enabling thicker electrode layers with out compromising structural integrity, this methodology permits for elevated vitality density, which might improve EV vary and effectivity. 

This method not solely improves the general efficiency of lithium-ion batteries but additionally drastically lowers manufacturing prices, and plenty of main gamers within the EV business are exploring the adoption of dry electrode expertise to streamline their battery manufacturing.

The dry course of does include its personal set of technical challenges, significantly round adhesion and uniformity. Making certain the electrode materials bonds successfully to present collectors with out solvents is a major hurdle, as is reaching constant mixing of elements. On this video, Upasani explains how Chemours is addressing these challenges via superior Teflon PTFE polymer formulations.
