Today’s growing economy requires innovative, new solutions that provide both better battery performance and cleaner energy solutions. With Protochips’ machine-vision powered suite of in-situ TEM tools you can utilize the electron microscope as a real-time laboratory to image and measure the underlying mechanisms that control the performance and behavior of energy materials on the nanoscale.
Fusion AX: Study high temperature heating, electrical and electrothermal in vacuum
Visualize the nanoscale processes that control solid-state battery material performance. Observe ion transfer reactions, growth kinetics, capacity degradation mechanisms and more without compromising resolution
