A small battery links all aspects of people's lives and plays a pivotal role.
On the intelligent assembly line, lithium-ion polymer batteries and nickel-metal hydride rechargeable battery products are continuously sent to the testing workshop and packaging workshop, and the products that pass the test will be transported to all parts of the world. This is the production workshop of Hunan Grepu New Energy Co., Ltd. (hereinafter referred to as "Hunan Grepu").
Hunan Grepu production workshop
Hunan Grepu is a national high-tech enterprise dedicated to the R&D, production and sales of green new energy lithium-ion and nickel-metal hydride batteries, and has built the province's largest nickel-metal hydride power battery and the largest high-rate UAV battery R&D and production base in China in the Chenzhou area and high-tech zone of the free trade zone.
A battery contains huge energy, and Hunan Grepu is a leading enterprise in the construction of "1221 modern industrial system" in Chenzhou City, a single champion product enterprise in Hunan Province, the first batch of national-level specialized, special and new key "little giant" enterprises in Chenzhou, and a national green factory, which has played an important role in promoting the process of green and sustainable economic development.
At the moment when the "involution" of the battery industry is serious, Grepu is developing day by day, why is it?
Innovation drives development
As we all know, everything is difficult at the beginning, and it is never easy for products to go from 0-1. This means starting from a completely new idea or concept and creating a completely new product that previously did not exist on the market.
Grepp chose to take this difficult path. Innovation is key in the process of going from 0 to 1 in a product. Talent and capital are important elements of innovation.
Over the years, Hunan Grepu has always adhered to the development path of independent research and development and scientific and technological innovation, and has a R&D team of nearly 300 people led by Professor Guo Huajun, Ph.D. supervisor of Central South University, and has successfully applied for more than 90 national technology patents. He has successively undertaken a number of scientific research projects at or above the provincial level, such as the "Science and Technology Innovation Leading Plan" of Hunan Province, "100 Scientific and Technological Innovation Products of Hunan Province", "Key R&D Projects of Hunan Province" and "Special Project for the Construction of Innovation Demonstration Zone of Chenzhou National Sustainable Development Agenda". The company is equipped with domestic advanced new energy battery product R&D and testing laboratories, and has built 7 provincial-level scientific and technological innovation platforms, including Hunan Provincial Enterprise Technology Center, Hunan Provincial Expert Workstation, and Central South University Industry-University-Research Cooperation Base.
Hunan Grepu R&D office building
Since Hunan Grepu entered Chenzhou, the annual sales compound growth rate has been more than 25%, and the proportion of R&D technology investment in sales revenue has been maintained between 5% and 6%, and the continuous investment has provided an inexhaustible source of power for the innovation-driven development of the enterprise.
Grepu has always adhered to its main business, intensively cultivated in the field of new energy batteries for more than ten years, and has successively developed a series of products such as TATTU UAV intelligent battery version 3.0, FPV drone battery 1550mAh-TATTU, inspection drone lithium battery 22000mAh, intelligent fast charging plant protection drone battery 16000mAh, high-endurance and large-capacity UAV battery.
These UAV batteries not only have the characteristics of high energy density, large discharge rate, long cycle life and long battery life, but also have the advantages of fast charging and wide temperature range (-50°C~50°C) use, and are widely used in aerial photography, agricultural plant protection, geological exploration, surveying and mapping, cruise, security, logistics and distribution, tourism and emergency rescue and other fields.

In addition to lithium polymer batteries, nickel-metal hydride batteries and lithium iron phosphate batteries, Grepu is also good at producing special battery products with various specifications and unique performance, and provides customers with private customized solutions to further meet the personalized customization needs of customers. The products are exported to more than 130 countries and regions, and the market share of domestic high-rate UAV series lithium-ion batteries reaches 80%.
Green preempts the future
As a high-tech enterprise focusing on green new energy, Hunan Grepu has always taken the protection of the ecological environment and sustainable development as the core concept of the enterprise, upgraded the industrial development structure of Chenzhou with green production, digitalization and informatization, and driven the green environmental protection and high-quality development of Chenzhou's industry with scientific and technological innovation.
This can be seen in the company's brand name. Grepow, composed of "Green" and "Power", is a symbol of "green, environmental protection and low-carbon new energy".
Where is the green embodied? It can be said in every way. It includes five aspects: green infrastructure, green management system, green environmental emissions, green energy resources, and green product design and production.
The company has built the first "new energy high-rate lithium battery smart factory" in Chenzhou and the leading one in Hunan with high standards, making up for the shortcomings of the intelligent manufacturing of high-performance lithium batteries in our province, and driving the green environmental protection and high-quality development of Chenzhou's industry with scientific and technological innovation. The raw materials of batteries do not contain harmful heavy metals such as cadmium, lead, and mercury, and almost no pollutants are produced during production and use.
The company increases the development and utilization of clean energy such as solar energy, and further improves the efficiency of energy utilization and reduces energy waste and loss through technological innovation and intelligent control measures. It has formulated a sound supplier management system, continuously optimized the raw material supply chain, resolutely put an end to the purchase of goods containing toxic and harmful substances prohibited by the state, and at the same time included the energy-saving products and green products released by the state in the scope of green procurement of enterprises, and actively carried out the recovery and recycling of waste materials and packaging materials.
Among them, the high-rate lithium-ion battery produced by the company is a representative of modern high-performance batteries, with the advantages of high energy density, long cycle life, low self-discharge rate, no memory effect, etc., and is regarded as one of the most ideal power batteries and the most ideal new generation of green energy. The technical level is in a leading position at home and abroad.
The green efficiency has gradually become prominent, and Hunan Grepu has been rated as "National Green Factory", "Hunan Green Factory", "Hunan Water-saving Enterprise", "Hunan Two-type Industrial Enterprise", "Chenzhou Environmental Protection Advanced Enterprise" and "Chenzhou Advanced Unit of Safety Production".
Energy storage low-altitude economy
This year's National People's Congress and the National People's Congress, the "low-altitude economy" was written into the government work report for the first time, which means that the mainland will vigorously develop the low-altitude economy, and the company's development will usher in a blue ocean.
As a pioneer in this field, the high-rate UAV series lithium-ion batteries developed by the company with the 811 material system will be widely used in low-altitude electric aircraft applications such as logistics and distribution, tourism and urban navigation, providing better "power support" for the high-quality development of the mainland's low-altitude economic industry. In 2023, with its outstanding performance in the field of low-altitude economy and in-depth contribution to the UAV industry, Grepu was awarded the title of "China's UAV Low-altitude Economy Benchmarking Enterprise".
The "Development and Application Project of High Energy Density and High Rate Lithium-ion Battery above 350Wh/kg" is being developed by Hunan Grepo, which will focus on solving the technical problems of the industry such as low energy density, short endurance (mileage) and slow charging speed of lithium-ion batteries for low-altitude electric aircraft, which will help promote the rapid development of the mainland's low-altitude economy, further release the reform dividend of "Hunan Province as the mainland's first full-range low-altitude flight pilot province", and help Hunan Province to build the low-altitude economy into a new growth point for the future economy.
In the future planning of Hunan Grepu, the company will set up Hunan Grepu Innovative Product Research Institute, cooperate with the upstream and downstream industrial chains for collaborative innovation, and develop more green series of "specialized, refined, special and new" high-end intelligent lithium-ion power battery products and solutions for low-altitude electric aircraft, meet the rapidly growing consumer demand, and strive to become the leader in the development of low-altitude economic industry in Hunan Province.
