Phenom ParticleX Battery Desktop SEM

Desktop scanning electron microscope for battery production and research

Advanced battery materials analysis

The Thermo Scientific Phenom Pharos G2 FEG-SEM brings field emission SEM to your tabletop. The Phenom Pharos G2 FEG-SEM will outperform many floor-standing SEMs in terms of image quality, while offering a vastly better user experience. For academic and industrial laboratories that so far did not consider SEM a realistic option, the Phenom Pharos G2 FEG-SEM makes FEG performance accessible thanks to its attractive form factor and short training required. Blazing fast sample loading means fast sample exchange, which means higher productivity. Unlike other SEMs, which end up being fully booked, the Phenom Pharos G2 FEG-SEM performs imaging and analysis jobs so quickly that it serves well as a walk-up tool.

The new Phenom Pharos G2 FEG-SEM expands its acceleration voltage range down to 1 kV, to better accommodate insulating and beam-sensitive samples, and up to 20 kV, with a resolution of 2.0 nm that reveals the finest details.

Advanced battery materials analysis
Phenom Desktop SEM designed for battery materials analysis

In battery production and research, the quality of materials is becoming critical. Small contaminants in the NCM powder, for example, can have disastrous results in the final product. To trace these contaminants effectively, high-resolution SEM imaging with EDS analysis for chemistry is needed. When fully automated, this combination is a powerful tool for powder quality inspection.


Phenom ParticleX Battery Desktop SEM key features


Conductance classifications

Each particle class can be labeled with a conductance of the particles, allowing you to sort on conductance of particles. This allows you to assess the impact of contamination much more accurately since a small organic contamination is not as severe as a metallic conductive contamination.

Ternary diagram

To view overall chemistry of the particle population, a ternary diagram can be generated where all particles are represented. With Ni, Co, and Mn on each axis, the outyears and general trends can be seen instantly.
