Company profile
researched Aug 2026Green Li-ion (Green Li-ion Pte. Ltd.) is a lithium-ion battery recycling technology company. It produces modular hardware systems that convert spent batteries into cathode and anode materials described as ready to be used directly in manufacturing processes for batteries of all types. Its process, branded GREEN HYDROREJUVENATION, takes crushed and shredded black mass and moves directly to production of GREENpCAM (precursor cathode active material), graphite, and technical-grade lithium carbonate (Li2CO3).
The company positions its technology around speed, purity, cost and energy reduction relative to existing recycling processes, and states a broader objective of closing the materials loop so that battery materials from electronic waste are reclaimed rather than discarded. The company's site references granted patents covering its battery recycling technology, and lists investors and government supporters among its backers without naming them in the material reviewed.
Founding story
Co-founder and CTO Dr. Reza Katal, a hydrometallurgy researcher with a Ph.D. from the National University of Singapore, developed the company's battery rejuvenation technology; Leon Farrant, a co-founder with two decades of experience in the global energy industry, serves as CEO.
Business model
Green Li-ion supplies modular hardware/technology systems for lithium-ion battery recycling and also produces recycled battery raw materials; the company has begun selling recycled Nickel-Cobalt-Manganese (NCM) hydroxide made from American-recycled feedstock via the Metalshub trading platform.
Sales of recycled battery raw materials (e.g., NCM hydroxide) alongside provision of modular recycling hardware/technology; specific pricing or contract structures are not disclosed in the sources.
Traction
Team of more than 40 professionals across five offices; a granted patent for its recycling technology; a letter of intent with EcoPro Materials for long-term recycled NCM hydroxide supply; and a first commercial sales event for recycled NCM hydroxide on Metalshub.
Latest developments
Recent announcements include a letter of intent with EcoPro Materials Co., Ltd. for a long-term strategic partnership on recycled NCM hydroxide supply, the launch of a first sales event for recycled battery raw materials on the Metalshub platform, an additional granted patent, and an SBR Technology Excellence Award in 2025.

Market position
Describes itself as a lithium-ion battery recycling technology provider; recognized in the Energy Distribution & Storage category of the SBR Technology Excellence Awards 2025.
The company states its process moves directly from crushed and shredded black mass to precursor cathode active material, graphite and technical-grade lithium carbonate, and claims improvements in speed, purity, cost and energy consumption relative to conventional recycling, delivered in modular hardware form.
Technology
The core technology, marketed as GREEN HYDROREJUVENATION, is a hydrometallurgical process that accepts crushed and shredded black mass and produces GREENpCAM precursor cathode active material, graphite, and technical-grade lithium carbonate. It is delivered as modular hardware. CTO Reza Katal, who holds a Ph.D. from the National University of Singapore and has more than a decade of experience in hydrometallurgical processing of lithium-ion batteries, developed the process. The company has been granted at least one additional patent on the technology.
Go-to-market
The company combines technology/hardware deployment with direct sales of recycled output materials, using strategic partnerships with precursor producers and a listing of NCM hydroxide on the Metalshub sales platform as distribution channels.
Battery and battery-material manufacturers requiring cathode and anode feedstock, battery precursor producers such as EcoPro Materials, and buyers of recycled battery raw materials on commodity trading platforms.
Geography
Headquartered in Singapore, with five offices worldwide and a stated global expansion focus; recycled raw materials sold on Metalshub are sourced from American-recycled feedstock.
