LS Materials launches UC 'Cellul' with 30% reduced volume and weight

First in Industry to Launch Product
with Cell Packaging Process Removed

LS Materials announced on the 19th that it has launched the world's first 'cell-module integrated' ultra capacitor (UC) called 'Celldul.'

Batteries are manufactured in a 'cell-module-pack' structure, but Celldul is a product that eliminates the cell packaging process. As a result, volume and weight are reduced by more than 30%, and energy density is increased. The production process is reduced by more than half, securing price competitiveness. Previously, multiple cells were assembled and then packaged to create a module, but Celldul connects the electric storage elements (jelly rolls) directly to form a module.

LS Materials expects Celldul to quickly replace existing cell-type products due to its high energy density and price competitiveness.

Hong Young-ho, CEO of LS Materials, said, "We are in discussions with customers to apply it to auxiliary batteries for automotive power output," adding, "We plan to expand the market focusing on robots, wind turbine generators, UPS (uninterruptible power supply), and ESS."

Celldul, along with the recently developed high-power load control system, was exhibited this month at the power semiconductor exhibition 'PCIM Europe 2024' held in Germany, attracting attention for its innovative features.

UC is an industrial special battery known for its advantages of high-speed charging/discharging and long lifespan. The industry expects the global UC market size to grow from $2.3 billion in 2020 to $8.5 billion in 2026, with an average annual growth rate of 25%.
