Yokohama – Lasertec Corporation announced today the release of ECCS B520, an electro-chemical reaction visualizing confocal system designed for the operando observation and measurement of all-solid-state batteries.

Lasertec has been providing the ECCS series to customers in the battery industry for many years, contributing to improvements in the quality of lithium-ion batteries used in electric vehicles and smartphones. The series has been particularly well received for use in R&D and defect analysis applications.

Recently, research on all-solid-state batteries has been conducted in earnest, and their sulfide-based variants require high confining pressures. The newly released ECCS B520 can perform the operando observation and measurement of samples while uniformly applying pressure at the megapascal level— a feat that was previously challenging to achieve.

We have also replaced the xenon lamp used in the previous model with an LED lamp, which has a longer lifespan and stable brightness, as the light source for the new model.

Lasertec remains committed to developing unique solutions that meet customer needs, facilitating quality improvement and productivity enhancement, and contributing to the advancement of the battery industry.
