SEC Supplies All-Solid-State Battery Inspection Equipment to Global Battery Company L... Showcases Technology at InterBattery

SEC, a company specializing in electron beam-based inspection equipment, announced on March 12 that it is currently undergoing a technology evaluation after supplying next-generation all-solid-state battery inspection equipment to a leading global battery company referred to as Company L. In addition, SEC has secured orders from several automakers for X-ray inspection equipment designed for prismatic and pouch batteries and is currently manufacturing the equipment for delivery.

On this day, SEC is participating in the 'InterBattery 2026' exhibition held at COEX in Seoul, showcasing its battery X-ray inspection technology. At this exhibition, SEC introduced its X-ray inspection solutions capable of supporting not only 46 mm cylindrical batteries but also prismatic, pouch, and next-generation all-solid-state batteries.

A representative from SEC stated, "As the battery industry rapidly evolves toward 46 mm cylindrical and prismatic batteries, demand for inspection equipment is also expanding." The representative added, "SEC's X-ray inspection technology enables precise analysis of internal battery structures and defects, attracting significant interest not only from global battery manufacturers but also from automakers."

He continued, "Through this InterBattery exhibition, we plan to actively expand our battery inspection equipment business and secure additional global clients." He added, "With the expansion of new equipment supply, our order backlog in the first quarter is expected to surpass 25 billion won, and based on this, we anticipate meaningful growth in annual sales, what we call a quantum jump."

The basis for this outlook lies in SEC's technological strength in electron beam and X-ray-based inspection and analysis. SEC possesses technology for electron beam and X-ray-based inspection and analysis equipment, expanding its business not only in batteries but also into high-bandwidth memory (HBM), advanced packaging, and the defense industry.

Recently, along with the growth of the electric vehicle market, batteries are rapidly increasing in energy density and size, heightening the importance of non-destructive inspection technologies capable of detecting internal defects with high precision. In particular, the 46 mm cylindrical battery is considered a next-generation battery with higher energy density and production efficiency compared to the conventional 2170 format. However, managing various quality defects such as electrode misalignment and internal foreign substances remains a key challenge.

In response to these market changes, SEC has developed and supplied battery inspection equipment that combines high-resolution X-ray inspection technology with artificial intelligence (AI)-based automatic inspection algorithms. SEC began supplying pouch battery inspection equipment in 2020 and has rapidly expanded its business by developing and selling inspection equipment for cylindrical batteries in 2023 and for prismatic and all-solid-state batteries in 2025.
