Dongwha Electrolyte (founded 2009) makes liquid and solid electrolytes, additives (PA800) and NMP recycling. With global plants and a 70,000+ t/y Tennessee facility, it supplies EV, ESS, consumer electronics and capacitor manufacturers.
Dongwha Electrolyte, founded in 2009 and headquartered in South Korea, manufactures high-stability electrolytes for lithium-ion and related battery technologies. A subsidiary of Dongwha Enterprise, the company expanded through the 2019 Panax Etec acquisition and opened its first U.S. facility in Clarksville, Tennessee (operational 2024–2025). Dongwha focuses on electrolyte formulations, additives, and recycling services (including NMP recycling) to support EV, energy storage, and consumer electronics markets. Its stated mission emphasizes sustainable battery performance and supply-chain localization through global manufacturing and R&D investment. Founders are not specified in available sources.
Dongwha Electrolyte develops and manufactures advanced liquid and emerging solid electrolytes for lithium-ion and related battery systems. Core capabilities include low-resistance, high-ionic-conductivity liquid formulations, high-voltage electrolytes, silicon-compatible chemistries, and fire-resistant mixtures with thermally stable and gas-suppressing additives. The company reports proprietary additives (e.g., PA800) intended to improve thermal stability, reduce gas generation, and optimize energy output for thick-electrode LFP cells. Dongwha also researches sulfide solid electrolytes for solid-state batteries and ceramic/polymer electrolyte systems. Complementary capabilities include NMP solvent recycling and an in-house R&D center that secures formulations through patents and certifications, enabling tailored electrolyte solutions for automotive and stationary energy applications.
Dongwha supplies liquid and emerging solid electrolytes, functional additives (including PA800), and NMP recycling services. Products target lithium-ion prismatic, cylindrical and pouch cells, LFP thick-electrode formats, lithium primary cells, supercapacitors, and solid-state/ceramic batteries. Applications include EVs, hybrid vehicles, energy storage systems (ESS), consumer electronics, power tools, and rapid-charge capacitive devices.
In 2025 Dongwha completed several supply agreements and capacity expansions. April 2025: a KRW 350 billion contract to supply electrolytes for green vehicles to a major U.S. battery and automotive manufacturer, to be produced at the Clarksville, Tennessee plant. July 2025: a 20,000-ton LFP electrolyte supply contract for ESS applications, sourced from the Malaysian facility (2026–2027 delivery window). August 2025: selected as an electrolyte supplier by a global automaker (details confidential). Tennessee capacity exceeds 70,000 t/y.
