1. Company Overview
- Company name: Shenzhen Geesun Intelligent Technology Co., Ltd. (formerly Shenzhen Geesun Zhiyun Technology Co., Ltd.)
- Founded: February 17, 2006
- Headquarters: Bao’an District, Shenzhen, Guangdong Province, China
- Business area: lithium-ion power battery production equipment (laser electrode-tab forming machines, high-speed automatic winders, high-speed composite stacking machines, etc.)
- Scale: approx. 900 employees, approx. 250 R&D personnel (27%)
2. History and Personnel
Founded in 2006, the company has grown into one of China’s original lithium battery equipment companies. In 2018, it was appointed to a director-level position at the Battery Alliance’s process equipment branch, launching a group-development strategy; in 2021, it established a Zhaoqing Zhaoyang branch to expand its manufacturing base and appointed academician Chen Liquan to establish an academician workstation. In 2023, it was designated a national-level ‘single-item champion’ manufacturing enterprise and completed a Series B+ funding round. Per Geesun’s investment history disclosed on 36Kr PitchHub, the company raised strategic financing in March 2010 (China Merchants Capital/BAIC Industrial Investment), July 2016 (Guoke Investment/Zhiyun Co.), and January 2018 (Suoyu Capital/China Youth Group/Congrong Investment), followed by a Series A round led by Hongshang Group in June 2022; specific amounts for each round are undisclosed.
Of approximately 900 employees, the R&D team accounts for about 250 (27%). The company has established research platforms including the Guangdong Lithium Battery Equipment Intelligent Manufacturing Process Technology Research Center, and since 2018 has pursued a group strategy by establishing subsidiaries such as Suzhou Geesun Automation.
3. Core Technology and Key Equipment
The laser electrode-tab forming machine achieves a processing speed of 150 pieces per minute, with the high-speed automatic winder and high-speed composite stacking machine as the other two of its four core pieces of equipment. The company holds 412 invention and utility-model patents (70% invention patents) and 25 international patents. Per a Sina Finance interview (2025-07-07, quoting Chairman Yang Lukun), the company’s patent count has since grown to over 800 (including 38 international patents); this figure is based on a company statement without cross-checking against third-party filings and needs independent confirmation.
- Laser electrode-tab forming machine — processing speed of 150 pieces per minute
- High-speed automatic winder (lithium battery winder)
- High-speed composite stacking machine (lithium battery stacker)
- Production equipment for supercapacitors
4. Production Infrastructure and Quality Assurance
The company operates its Bao’an District, Shenzhen headquarters/research center and a Suzhou automation subsidiary (established in the Kunshan High-Tech Industrial Zone in 2010), with a sales and service network extending across South China, East China, North China, and Central China domestically, as well as into Southeast Asia and the US market.
5. Delivery Track Record and Partnerships
The company states its customers include industry leaders such as CATL and BYD. An OFweek Lithium Battery Network report (2023-07) on an industry-wide CATL supply-chain order package worth RMB 28 billion named Geesun as a CATL supplier, but did not disclose Geesun’s individual contract amount (needs confirmation). Other individual contract details are (undisclosed).
6. Financial Status and Roadmap
As an unlisted company, Geesun states it completed a Series B+ funding round in 2023. However, the investment history disclosed on 36Kr PitchHub lists only a June 2022 Series A round led by Hongshang Group, with no separate Series B+ round shown; the round name and timing require cross-checking (needs confirmation). Individual revenue/profit figures are (undisclosed).
Based on core invention patents in winding, stacking, and laser cutting, the company is leading technology standardization by participating in the establishment/revision of international standards (8 national standards, 3 local standards, and 2 industry standards). In the 2025-07-07 Sina Finance interview, Chairman Yang Lukun stated the company has led the drafting of over 70 power-battery manufacturing standards, and cited a 95% equipment interconnection rate at its digital workshops and a reduction in thermal-runaway probability to below 0.01% as internal achievements (company statement without third-party verification; needs confirmation).
