SungEel HiTech is a battery recycling specialist established in March 2017 when the secondary-battery recycling division was spun off from SungEel HiMetal.
Its business is split into pre-treatment, which dismantles and shreds spent batteries into black mass, and post-treatment via hydrometallurgical Hydro Centers that recover nickel, cobalt, lithium and manganese.
Domestically, the Gunsan No.1 and No.2 plants have aged, while the highly efficient Hydro Center No.3 in Saemangeum now serves as the core production hub for lithium, nickel and cobalt.
Overseas sites are spread across Hungary, India, Malaysia, Poland, Indonesia and the United States, and as of 2025 the company had secured total capacity of about 95,000 tons (25GWh) across six countries.
In Batonyterenye, Hungary, the company completed Plant 1 in 2019 and Plant 2 in 2021, giving it 60,000 tons of black-powder processing capacity, the largest overseas production footprint the company holds.
Samsung SDI is a key customer and also the third-largest shareholder with roughly an 8% stake, having served as a strategic investor supplying materials and offtake since the company's early days.
SungEel HiTech has also signed a cobalt and nickel sulfate supply contract with Morocco-based COBCO, and is now discussing scrap-processing cooperation with Ecopro, which is preparing to ramp up its cathode material plant in Hungary.
Competitively, the company's track record recycling NCM and NCA ternary batteries, combined with preparations to commercialize LFP battery recycling amid rising demand for that chemistry, is seen as giving it relatively broad product coverage.
