Yunnan Polytechnic Hengda New Energy Technology Co., Ltd. is a wholly-owned subsidiary of Kunming Polytechnic Hengda Technology Co., Ltd., which was established in November 2021. Its main business scope is battery manufacturing, new energy prime equipment manufacturing; New energy technology research and development; Recycling and cascade utilization of waste power batteries of new energy vehicles (excluding hazardous waste management); Manufacturing of synthetic materials (excluding hazardous chemicals); Sales of new energy vehicle power exchange facilities. In September 2022, the company fully passed the certification of quality management system, environmental management system and occupational health management system. At present, a battery R&D base has been established in Qilin District, Qujing City, and a new lead-carbon energy storage battery assembly production line project has been completed.

In recent years, China has continuously strengthened the regulation and guidance of electrochemical energy storage technology. In 2010, the development of energy storage was written into the bill for the first time. In March 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage in the "Fourteenth Five-Year Plan" to promote the rapid, high-quality and large-scale development of new energy storage. The domestic energy storage technology has been continuously developed, especially the lead-carbon battery energy storage technology in electrochemical energy storage, which has made great breakthroughs and improvements. The large-capacity long-term energy storage technology is an important link to enhance the security and flexibility of the energy system supply and improve the comprehensive efficiency, and is the key technology to support the efficient and safe energy transformation in the future. Whether it is new energy vehicles or new energy power generation, the core pain point is energy storage. Professor Guo Zhongzhong, the founder of Kunming University of Technology, has summarized the advantages and disadvantages of lithium-ion batteries and conventional lead-carbon batteries by taking advantage of his professional advantages in metallurgical and electrochemical research and application, summarized and drew lessons from the research and application status of electrochemical energy storage batteries at home and abroad, and combined with the company's years of experience in producing lead alloy anodes, especially the first low-carbon green aluminum-based lead alloy composite anode, First of all, starting with the core grid material preparation technology of lead-carbon batteries, the company's original aluminum-based lead alloy composite material was applied to conventional lead-carbon batteries to replace the original lead alloy grid, and the new large-capacity lead-carbon long-term energy storage battery preparation technology and products were first created, which greatly expanded the market application prospects and space of new energy storage.

As an important part of the future energy storage technology, lead-carbon battery has the advantages of mature production process, low production cost, low raw material cost, safety and stability. With the continuous improvement of performance and technological progress, it will also show its absolute advantages in the field of energy storage in the future, such as large capacity, rich raw material reserves, recyclable and easy to manufacture. At the same time, the 99% recovery rate of lead-carbon batteries and strict regulations on lead environmental emissions have greatly improved the environmental friendliness of lead-carbon batteries and ensured a strong economic, technical and policy environment to support the rapid and long-term development of lead-carbon batteries. The global lead-carbon battery industry will continue to provide reliable and high-performance batteries to promote global electrification and achieve the goal of decarbonization of the whole society.

According to the prediction of China Photovoltaic Industry Association, during the "Fourteenth Five-Year Plan" period, the annual average installed capacity of photovoltaic wind power in China will be 150GW, at least 800GW by 2030, and at least 3000GW by 2060. According to the calculation of 10% to 20% allocation of energy storage, during the "Fourteenth Five-Year Plan" period, the average annual new installed capacity of photovoltaic wind power industry is 15GW/47GWh to 30GW/94GWh. According to the analysis, it is expected that the global new energy storage demand will reach 163GW/511GWh in 2025, the energy storage market space will exceed 600 billion, and the five-year compound growth rate will be 90%. In the long run, it is expected to reach trillion market space. Among them, large-capacity lead-carbon batteries have the most potential for energy storage, with a market of several trillion dollars. The new type of lead-carbon long-term energy storage battery of Kunming Industrial Technology Co., Ltd. is bound to have a bright future
