Anhui Langyue Energy Co., Ltd., one of the national standard drafting units, the low-carbon industrialization base of small and medium-sized enterprises of the Ministry of Industry and Information Technology, a full member unit of the Lithium-ion Battery Safety Working Group of the Ministry of Industry and Information Technology, and a national foreign aid project cooperation unit of the International Semiconductor Lighting Alliance.

The company focuses on the research and development and production of graphene-based lithium-ion batteries, solar + lithium battery energy storage microgrid power supply systems, lithium battery intelligent solar street lights, solar Internet of Things street lights and other series of products, for smart transportation, road lighting, new rural lighting, and security. Provide overall photovoltaic energy storage solutions in the fields of monitoring, home energy storage, communication base stations, etc. The company has a high-standard physical factory and advanced graphene-based lithium battery and lithium battery storage and control system production line; it has gathered a core management team and an excellent R&D team with hard research, and jointly developed a photovoltaic power generation and energy storage series with domestic universities such as Shanghai University. Products have been industrialized in China by the concepts of green, energy-saving, low-carbon and environmental protection. At present, we have mastered many core technologies of solar street lights: lithium battery storage and control technology, Internet of Things and narrowband Internet of Things technology, breaking through the bottleneck of lithium battery energy storage system that cannot work normally in extreme cold conditions, and independently developed the environment and climate characteristics of different regions. High-performance products such as Lubawang, Yinyuwang, and Extreme Coldwang are designed for different scenarios. The company's products have been exported to more than 30 countries and regions including India, Jordan, Saudi Arabia, Mongolia, Paraguay, Uganda, Spain, Singapore, Malaysia, Thailand, the Philippines, Kenya, etc.

The company has independent trademarks and intellectual property rights, and has more than 40 national patents, including 5 invention patents, more than 160 product testing reports and certification certificates, and 1 copyright for the Internet of Things solar street light control software. The company led the drafting and participated in the preparation of GB/T33766-2017 "Technical Requirements for Independent Solar Photovoltaic Power Supply System", CQC1126-2017 "Technical Specifications for Lithium-ion Battery Packs for Solar Street Lights", T/CSA039-2019 "Light Solar Street Lights Powered by Lithium Battery Technical Specifications" and other national, industry and alliance standards.
