What Guangdong Jiayuan Technology does

Guangdong Jiayuan Technology Co., Ltd. (广东嘉元科技股份有限公司), listed on the Shanghai Stock Exchange STAR Market (stock code 688388) since July 22, 2019, is a Chinese materials manufacturer specializing in the research, production, and sale of high-performance electrolytic copper foil, composite copper foil, and high-precision copper alloy wire and rod. The company's core product is electrolytic copper foil in thicknesses ranging from 3.5μm to 18μm, with proprietary electrodeposition processes, surface treatment capabilities, and additive formulations that it claims rank at internationally leading levels, particularly at the 3.5μm ultra-thin end. Product variants include double-sided light copper foil, high-strength high-ductility copper foil, RTF (reverse-treated) copper foil for high-frequency PCB, microporous copper foil for solid-state batteries, nickel-plated copper foil, IC packaging copper foil, and composite copper foil.

The company operates seven production bases across Guangdong, Jiangxi, Fujian, and Hunan, with combined annual copper foil capacity exceeding 135,000 tons and copper alloy wire/rod capacity above 20,000 tons, supported by 746 intellectual property rights and a workforce of over 3,400 employees. It is qualified as a National Enterprise Technology Center, National Technology Innovation Demonstration Enterprise, and National Intellectual Property Demonstration Enterprise.

Jiayuan runs a B2B enterprise sales motion with direct, long-term strategic cooperation agreements and quote-based pricing negotiated with anchor customers including CATL (宁德时代), BYD (比亚迪), EVE Energy (亿纬锂能), Tianjin Lishen, and Sunwoda. Its primary segment is lithium-ion battery manufacturers (EV power, energy storage, and increasingly solid-state batteries), with secondary exposure to PCB/CCL makers and IC packaging end markets. The company also exports to Japan, Korea, Europe, the US, and — most recently — Malaysia (first shipment August 2025). In FY2025, revenue reached CNY 9.643 billion (+47.85% YoY), with Q1 2026 revenue of CNY 3.445 billion (+73.94% YoY). It has begun diversifying into adjacent verticals via a 500 million yuan strategic equity investment in Enda Tong (optical modules).
