" Sodium battery, Korea's first innovative secondary battery "

Innovation in sodium material
While having the same thermal efficiency as lithium, sodium forms a price point that is about 40% lower than lithium. Additionally, the electrolyte sodium has a low risk of explosion due to its characteristics. It can be said to be an innovative material because it can ensure stability in the secondary battery market.
Energy 11's business fields
Energy 11 presents innovative values in the secondary battery market,
including industrial, commercial, and residential environments.

As the demand for renewable energy increases due to the government's nuclear phase-out policy, the solar ESS market is on the rise. In order to quickly respond to this market change, 'Energy 11' plans to integrate sodium secondary batteries into solar ESS.
Solar ESS

Electric bus
As demand for electric buses increases due to the domestic policy of replacing eco-friendly vehicles, Energy 11 plans to integrate sodium secondary batteries into route buses with adjustable charging cycles.


Industrial/Residential ESS
In preparation for the 4th industrial revolution, ‘Energy 11’ will integrate sodium secondary batteries into an energy management system equipped with a small ESS of 1MW or less based on IoT.
