What ISKY does

ISKY Chemicals Co., Ltd. (埃索凯科技股份有限公司) is a privately held, joint-stock limited company founded in 2000 and headquartered in Changsha, Hunan, China. The company operates three business segments: Energy Power (battery-grade manganese sulfate, nickel sulfate, cobalt sulfate, lithium carbonate, and LFP battery PACK products for EV and energy storage customers), Life Nutrition (zinc sulfate, manganese sulfate, copper sulfate, ferrous sulfate, magnesium sulfate, cobalt sulfate, nickel sulfate, zinc/magnesium oxides, and feed-grade amino acids for global agriculture and animal feed customers), and Circular Economy (processing zinc-containing industrial solid waste and spent power batteries into secondary zinc resources, ternary precursors, and manganese tetroxide). Underlying technology rests on high-purity manganese sulfate processing developed at scale since 2009, rotary-kiln zinc-waste volatilization feeding a 45,000-ton/year feed-grade zinc sulfate line, and three licensed-in patents covering cathode material regeneration and manganese-rich leachate metal extraction that underpin a 40,000-ton/year spent battery recycling and 10,000-ton/year ternary precursor operation in Guangxi.

ISKY's go-to-market is direct B2B sales to enterprise customers, supplemented by wholly-owned sales subsidiaries in North America (Ohio), Hong Kong, and Malaysia (Johor). Named customers include CATL subsidiary Brunpu Cycle, Huayou Cobalt, Umicore, CNMC Rumu Nickel Cobalt, and Jinch Energy on the battery-materials side, and Royal DSM, CP Group, ADM, Cargill, Brenntag, Syngenta, and Zinpro on the animal-nutrition side, with products distributed across more than 80 countries. The business model is hardware sales of industrial chemicals and battery precursors, with revenue generated on a quote-based B2B basis; no publicly disclosed pricing exists. ISKY operates a network of wholly-owned Chinese subsidiaries in Changsha, Qinzhou (Guangxi), Shenzhen, and Hangzhou, plus international sales entities, and has completed shareholding reform in 2020 in a structure consistent with pre-listing preparation, though no IPO has been filed. Recent compliance work includes CCCMC, OECD, and EU Battery Regulation-aligned responsible-minerals due diligence (April 2025) and a manganese sulfate carbon footprint verification report (May 2025).

Revenue model

1. Battery-grade manganese sulfate, nickel sulfate, and cobalt sulfate sales: ISKY manufactures and sells battery-grade manganese sulfate, nickel sulfate, and cobalt sulfate for use as cathode materials in lithium-ion batteries for electric vehicles, energy storage systems, and consumer electronics. This represents the primary revenue driver in the energy power segment.
2. Animal and plant nutrition product sales: ISKY produces and sells zinc sulfate, manganese sulfate, copper sulfate, ferrous sulfate, magnesium sulfate, cobalt sulfate, feed-grade amino acids (methionine, isoleucine, valine, arginine, lysine HCl, lysine sulfate, threonine), and other trace element products for agriculture and animal nutrition. Products are sold globally to international customers.
3. Circular economy / recycling processing services: ISKY Circular Economy subsidiary processes zinc-containing industrial solid waste and spent power batteries for recycling. Revenue is generated from processing hazardous waste materials and selling recovered zinc-based products, as well as ternary precursor production from spent battery recycling.

Core offering

ISKY manufactures and sells battery-grade manganese sulfate, nickel sulfate, cobalt sulfate, and lithium carbonate used as cathode precursors for lithium-ion batteries in electric vehicles and energy storage systems. It also produces trace element products (zinc, manganese, copper, magnesium, ferrous, cobalt sulfates) and feed-grade amino acids for animal and plant nutrition, alongside circular-economy recycling of spent power batteries into ternary precursors and processing of zinc-containing industrial solid waste.

Product overview

ISKY Technology Co., Ltd. operates as a diversified technology company with three core business segments: Energy Power, Life Nutrition, and Circular Economy. The Energy Power segment centers on battery-grade manganese sulfate (the company's founding product developed in 2009), along with battery-grade nickel sulfate, cobalt sulfate, and lithium carbonate for EV and energy storage batteries, complemented by LFP battery PACK products (LFP72V50Ah, LFP48V24Ah, LFP24V280Ah). The Life Nutrition segment provides trace element products including zinc sulfate, manganese sulfate, copper sulfate, magnesium sulfate, ferrous sulfate, and amino acids (methionine, lysine, threonine, valine, isoleucine, arginine) for plant and animal nutrition. The Circular Economy segment focuses on power battery recycling, recovering nickel, cobalt, manganese, and lithium from 40,000 tons of waste batteries annually to produce 10,000 tons of ternary precursors, alongside a 6,000-ton manganese tetroxide production line. The company has established a global sales network reaching over 80 countries and regions.
