Aiel announced on November 6 that it had completed development of roll-to-roll equipment for manufacturing lithium-metal anodes, based on its proprietary patented technology.

The equipment is significant because it puts into an actual continuous manufacturing process Aiel's core technologies related to lithium-metal anode materials and protective layers. In particular, by bringing not only materials development but also key manufacturing processes and equipment technology in-house, the company has further strengthened the technological foundation of its next-generation battery business.

The roll-to-roll process is a manufacturing method in which roll-shaped materials are moved continuously while undergoing processing and surface treatment. It can be designed to enable continuous production of lithium-metal anodes and is considered a key technology for future large-scale production, improved manufacturing efficiency, and cost competitiveness.

Aiel previously filed a patent for "Lithium-Metal Anodes Including a Dual-Functional Protective Layer with Improved Ionic Conductivity and Physicochemical Stability, and a Continuous Manufacturing Method Thereof."

The technology centers on a dual protective layer (DPL) structure designed to suppress the formation of lithium dendrites, one of the key challenges to commercializing lithium-metal batteries, and a continuous manufacturing process in a vacuum environment.

Lithium metal is a next-generation anode material capable of achieving high theoretical energy density. However, dendrites formed during charging and discharging and interfacial instability have made achieving longer lifespan and safety a significant challenge.

Aiel is considering expanding the application of this technology beyond all-solid-state batteries to various fields, including humanoid robots and future mobility, where high energy density and lightweight design are required.

"Completing development of this roll-to-roll equipment is significant because it puts our proprietary core technology for lithium-metal anodes into an actual manufacturing process," said Ko Jaehwan, head of the Battery R&D Center. "We are not stopping at securing materials technology; we are also bringing key process and manufacturing equipment technologies in-house to enhance the maturity of next-generation battery technology."
