Facts At Your Fingertips: Milling for Particle Size Control

Milling is commonly used for particle-size reduction and control of particle-size distribution (PSD) for crystalline solids. Mills are effective for generating consistent solids properties, through size reduction and surface-modification mechanisms [1]. This one-page reference outlines the mechanical forces involved in…

Controlling Process Variables for Solid-State Battery Performance

Optimizing electrical conductivity in next-generation batteries depends on carefully controlling process variables, such as mixing, particle-size distribution and temperature. Presented here is a discussion of how these process variables affect battery performance In the evolving landscape of energy storage technologies,…
