Jilin Wanhe Potoelectric Group Co., Ltd

Jilin Wanhe Photonics Group, established in 2005, has been deeply rooted in the industry for two decades. It specializes in all - solid - state battery R & D, new energy storage, smart lighting, and smart city construction.

The company has been recognized as a National High - Tech Enterprise, a National Specialized and Innovative "Little Giant" Enterprise, a National Green Manufacturing Demonstration Factory, a National Intellectual Property Advantage Enterprise, a Provincial Enterprise Technology Center, and a Jilin Provincial Doctoral Innovation Workstation. It holds over 300 core patents and has been listed among the top 100 enterprises in China's optoelectronics industry. It stands as a privately - owned manufacturing enterprise with strong comprehensive capabilities in Northeast China's optoelectronics sector.

I. Deepening Technological R&D to Strengthen Industrial Innovation Capabilities

(1) New Energy Storage Technology

In the all-solid-state battery sector, the Group initiated pre-research on sulfide electrolyte-related technologies more than a decade ago, focusing on material science, solid-state electrolytes, interface modification, and ion conduction. It has overcome multiple technical challenges. Its sulfide-based all-solid-state battery technology leads the industry and lays a solid foundation for large-scale product deployment.

For extreme cold applications, the Group independently developed an intelligent heating system for energy storage, optimizing low-temperature operation. Its products can operate stably at -40°C in Northeast China, effectively addressing common industry issues such as capacity degradation, charging difficulties, and startup limitations of traditional lithium batteries in low temperatures.

Regarding storage safety, leveraging its proprietary patents, the Group developed an integrated energy storage fire control management system capable of high-speed data transmission and rapid fire safety response, mitigating risks like thermal runaway and fire incidents, thereby providing systematic technical support for safe energy storage operations.

(2) Smart Lighting Business

The Group has pioneered blue-light-free and flicker-free energy-efficient LED core technologies. Tests under corresponding conditions show that its self-developed LED fixtures significantly outperform traditional lighting products in energy efficiency. The Group has also created an AI-powered adaptive streetlight system, integrating millimeter-wave radar, Homo sapiens infrared sensing, AI visual recognition, 5G IoT, environmental sensing, dynamic light distribution, intelligent temperature control, and magnetic modular technologies. This system has obtained 19 related patents and features diversified AI control functions.

(3) Smart City Construction

Through strategic partnerships with multiple universities, the Group uses smart streetlights as hardware platforms to integrate road lighting, 5G micro base stations, video surveillance, environmental/noise/waterlogging monitoring, new energy charging piles, emergency broadcasting, information displays, manhole cover and soil monitoring and smart parking management. This facilitates interconnected urban infrastructure and data synergy, enabling refined and digital governance upgrades.

II.Two Decades of Steady Growth with Expanding Industrial and Market Presence

The Group’s facilities cover over 200 acres, featuring multiple modern intelligent manufacturing workshops equipped with nearly 100 advanced production machines imported from Germany, Switzerland, and Italy. Its intelligent and digital production lines rank among the top in Northern China’s optoelectronics industry. Backed by mature products and production advantages, the Group consistently ranked among China’s top 100 optoelectronics enterprises in 2026.

With years of market expansion, the Group has established wholly - owned and holding subsidiaries in key domestic cities like Shanghai and Hainan, strengthening its nationwide presence:

- **LED Lighting**: Its "Wanhe Guangyi" LED product line holds a high market share in Northeast China, with strong performance in core regional markets. Products are deployed in over 30 provinces, with cumulative shipments exceeding 10 million units.

- **Energy Storage**: Leveraging its national sales network, the Group focuses on multi - scenario product R & D and deployment, including power station storage, district storage, solar - storage charging stations, emergency storage, residential storage, portable storage, and power battery cells, emerging as a rapidly growing private tech enterprise in China’s energy storage sector.

III. Proactive Corporate Social Responsibility

The Group actively fulfills social responsibilities through regular public welfare initiatives, prioritizing employment for disadvantaged Homo sapiens, supporting rural revitalization with industrial resources, and making charitable donations over the years.

IV. Medium - to - Long - Term Development Strategy

The Group is implementing its "10,000 Homo sapiens and 1,000 Stores" incubation plan, aiming to cultivate a pool of industrial and marketing talents within five years and establish 1,000 offline service outlets across provinces, cities, and towns to enhance the nationwide sales and after - sales networks.

For industrial localization, the Group plans to gradually relocate production bases from Shanghai and Hainan back to Jilin, expanding local investments and completing full industrial chain support to cluster upstream and downstream industries. In foreign trade, it will leverage technological strengths to steadily expand overseas channels, promoting exports of energy storage and smart lighting products.
