Evermore Opens Battery R&D and Production Hub in Naju

Accelerating Customized Development and Demonstration

Evermore Technologies, a next-generation battery material company, announced on April 25 that it has opened the 'Evermore Arc Center,' a base for next-generation battery development and prototype production, in Naju, Jeollanam-do.

Evermore is a global energy material company headquartered in New York, United States, and has established a vertically integrated development system encompassing material synthesis, cell manufacturing, electrolyte development, and performance verification. Evermore's main product, silicon anode material, can provide up to ten times the theoretical capacity (3600mAh/g) compared to conventional graphite-based anode materials. As a result, it is attracting attention as a key next-generation material that can extend the driving range of electric vehicles and enhance the performance of high-density compact devices.

However, during the charging and discharging process, silicon anode materials experience up to 300% volume expansion, which leads to electrode structure destruction and reduced lifespan. These issues have long been regarded as major technical challenges for the commercialization of silicon anode materials. To overcome these limitations, Evermore has combined composite material technology with precise process control capabilities to develop a high-performance silicon anode platform that simultaneously suppresses expansion, ensures structural stability, and achieves long lifespan.

The newly opened Evermore Arc Center is equipped with an integrated process infrastructure, including electrode slurry synthesis, coating, full-spec pouch cell assembly, and electrochemical testing facilities. This enables high agility in customized development and demonstration speed for clients. Evermore is also independently developing a 'dedicated electrolyte for enhancing the lifespan and interfacial stability of silicon electrodes.' Such integrated design and execution optimization across the electrode-electrolyte-cell structure are decisive factors in accelerating commercialization and enhancing quality reliability.

In addition to silicon lithium-ion cells, the Evermore Arc Center is also engaged in the development of next-generation battery technologies based on solid and quasi-solid electrolytes. Evermore plans to unveil a solid-state battery prototype by the end of this year. The company is also pursuing a next-generation electrode material strategy that meets both high performance and environmental sustainability.

Next month, Evermore will participate in 'InterBattery Europe 2025' in Munich, Germany, where it will unveil for the first time its integrated platform encompassing silicon composite anode materials, solid-state battery prototypes, and electrolyte technologies. Rather than simply exhibiting products, this event is expected to serve as a forum for discussions on technological co-development, licensing agreements, and strategic partnerships with global material and battery companies.

Meanwhile, the opening ceremony held the previous day was attended by Yoon Byungtae, Mayor of Naju, Lee Jaenam, Chairman of Naju City Council, Seo Eunsu, Director General of Job Creation and Investment Promotion at Jeollanam-do, Michael Lee, Chairman of Evermore, as well as other key figures from the government, political, and industrial sectors.
