As battery developers and manufacturers strive to combine even greater power
storage and output into lightweight, fast-charging products, the Mastersizer
2000 laser diffraction particle size analyzer from Malvern
Instruments is proving valuable in characterizing the materials used to
make electrodes.
The particle size distribution of battery electrode materials influences the
rate of electrochemical reaction within the cell, having an effect on both the
power density and storage capacity of the finished product. With its unique
optical setup, the Mastersizer 2000 allows comprehensive characterization of
the mixtures of nanometre and micron sized particles often used in electrode
production. The resulting data inform electrode design, ultimately influencing
the battery’s final performance.
Fast, accurate and having a dynamic range of 0.2 to 2000 microns, the Mastersizer
2000 comfortably covers those sizes of interest for battery production. Consistent
sensitivity across this range ensures accurate measurement of each size fraction,
especially important when analyzing polydisperse materials.
