Lithium-Ion Batteries

Grinding

Realize thousands in cost reduction and combined profit by perfecting your battery electrode production process

The performance of the lithium-ion batteries you produce is significantly influenced by the calender rolls in your machinery. The electrode coating compaction process requires extreme grind tolerances on calender rolls to ensure proper functionality and performance in an electrode.

 

Only PRG grinds to the tolerances required for advanced battery manufacturing

PRG provides the tightest grinding tolerances in the world — as precise as 40 millionths of an inch TIR. The rolls you receive from PRG are serviced and ground to the proper roundness, TIR and surface finish — all critical to building a better battery.

Improve your battery cell performance and life

In-spec calender rolls yield reduced electrode caliper variation, and reduced porosity variation leading to better wettability. Variation reduction also makes for or leads to improved packaging. This improves not only the battery’s energy density, but also charge/discharge rates and cycle life.

Reduce Your Material Usage and Costs

The result of a better product profile means less scrap and a reduction in raw material costs. Less calender scrap also means greater coating efficiency, as less coated material is scrapped after calendering.

Increase your production line efficiency

With the proper TIR and surface finish, calender rolls have a more uniform nip. Electrode calendering requires fewer adjustments, and overall part-to-part variation is reduced. This adds up to more run time and the production of more quality electrodes.
