Atmosphere is an advanced product that enables heating and imaging in real-world gases and pressures—opening up discoveries and results that were not possible before. Atmosphere is optimized for analytical data collection, which makes it easy to adjust sample temperature, gas composition and pressure while imaging in the microscope.

Case Study

Lithiation and Delithiation in Batteries  A key challenge in the development of lithium-ion battery materials is combating the formation of lithium dendrites on the electrode surface after repeated charge/discharge cycles. Using Protochips’ Poseidon Select system, researchers successfully imaged the formation of lithium dendrites during battery charge/discharge cycles, while simultaneously collecting electrochemical data using STEM.
