The State Intellectual Property Office recently granted “A lead-acid battery colloidal electrolyte (Patent No. ZL20051006856.9)†to Chaowei Power Co., Ltd. as the China Patent Excellence Award, which is the only national patent award won by the national battery industry.
It is reported that this invention patent of Chaowei Company was made by the technical backbone of the company in January 2005 with nano-silica, carboxymethyl cellulose salt, stannous sulfate and other raw materials. After two years of dozens of trials. A new type of colloidal electrolyte for lead-acid batteries was invented. The invention and application of this technology broke the long-term blockade of the high-end production technology of China's batteries by developed countries, and overcame the technical bottleneck of lead-acid batteries at temperatures below -35°C and temperatures above 55°C, and at the same time made the battery The cycle life is more than double the national standard, solving common technical problems in the development of the battery industry. Chaowei Company's “Long-life, colloidal sealed lead-acid batteries for electric vehicles†produced by this invention patent has been listed by the Ministry of Science and Technology as a National Torch Program Project, a Torch Program Key Project, and a National Key New Product, covering all provinces and cities in China. And exports to more than 10 countries and regions in Europe and Asia, with annual sales of more than one billion yuan.
In recent years, Chaowei Company has increased its investment in innovation funds, the construction of innovative platforms and the introduction of high-level talents. It has tackled the common technical problems in the industry and has achieved major breakthroughs. It has applied for 135 patents, of which 11 have been authorized for invention patents.
