On the occasion of the 90th birthday of the Institute of Physics of the Chinese Academy of Sciences, the first low-speed electric vehicle with a sodium ion battery was demonstrated in the Physics Park. The electric vehicle was established by relying on the Institute's sodium ion battery technology. Responsible company launches.

Low-speed electric vehicles are also known as 'national vehicles'. In China's third and fourth-tier cities, rural and developing countries have a vast market demand. In March 2018, the "Ministry of Industry and Information Technology Department of the State Council released the "2018 New Energy Vehicle Standardization Work Points". For the first time, low-speed electric vehicles are included in the category of new energy vehicles, and low-speed electric vehicles will usher in the prime time of market layout. At present, more than 90% of low-speed electric vehicles use lead-acid batteries as a power source, and lead-acid batteries account for certain costs. The advantage, but its life is generally only 1-2 years, and the old batteries have environmental pollution problems. Low-speed electric vehicles in order to get long-term development, it is necessary to develop a more comprehensive and better performance and environmentally friendly battery technology.
Since 2011, the R&D team led by Professor Hu Yongsheng has been researching and accumulating lithium batteries for more than 30 years. He has devoted himself to the research and development of low cost, safety and environmental protection, and high performance sodium ion battery technology. The intellectual property sodium-ion battery system has applied for more than 30 invention patents in key materials such as positive electrodes, negative electrodes, electrolytes, additives, and adhesives; 12 invention patents have been granted, including 1 each of the United States and Japan patents. The system uses the resource-rich sodium as the active element, and the positive and negative materials use low-cost sodium-copper-iron-manganese oxide and anthracite-based soft carbon, which has obvious cost advantages. After seven years of hard work, researcher Hu Yongsheng leads. The research and development team continued to make breakthroughs in scientific research and technology. At present, the energy density of sodium-ion batteries has reached 120 Wh/kg, which is about 3 times that of lead-acid batteries. Low-cost sodium-ion batteries are expected to be used in low-speed electric vehicles. , Home energy storage, Grid energy storage and other fields have been applied.
In 2017, physical science and technology related to the sodium-ion battery technology funded the establishment of Zhongke HaiNa Technology Co., Ltd., which was the first company in China to focus on the development and manufacture of sodium-ion batteries. Subsequently, Zhong Kehai Sodium Corporation in Jiangsu Liyang Prepare to set up an industrialization base to accelerate the commercialization of sodium-ion batteries, from basic research and development of electrode materials to scale-up preparation and production, from materials to batteries, from single cells to battery modules, from battery modules to low-speed electric vehicles, solid Advancing, steadily moving forward. Today, the first low-voltage electric vehicle with sodium ion battery finally unveiled, which indicates that the commercialization of sodium-ion battery is about to start!
