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.
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.
