On August 16, the first phase of the lithium iron phosphate precursor 400,000 tons/year iron phosphate project started in Binzhou, Shandong. This means that Li Changming, an academician of the European Academy of Sciences, and Dr. Xin Minchang, chairman of Jiuhuan Energy Storage Technology Co., Ltd., have entered the stage of marketization of new achievements jointly developed by them for five years.
Dr. Wu Chao, chief expert and chief engineer of Jiuhuan Xinyue New Energy Battery Materials Co., Ltd., said that compared with the traditional process, the new production process of iron phosphate and the new material system of iron phosphate precursor focus on high-end, with "two new , three highs, two lows, and no three wastes". Specifically, the lithium iron phosphate precursor material produced by this new process has a new process and a new material system. The lithium iron phosphate battery produced by this precursor material has higher energy density, stronger low-temperature performance, and higher comprehensive benefits. The discharge efficiency is more than 40% higher than that of similar products in a low-temperature environment of -20°C, and the production efficiency is doubled. At the same time, this process has the advantages of low energy consumption and low sewage output, and can recycle waste acid and waste gas in Shandong and surrounding areas to produce high-quality sewage treatment agents.
Dr. Xin Chengxun, President of Jiuhuan Energy Storage Technology Co., Ltd., introduced that the project is mainly used to produce lithium iron phosphate and lithium iron manganese phosphate materials, which are used in new energy vehicle batteries and energy storage batteries. After the completion of the project, it can achieve an annual output value of 52 billion.
It is understood that iron phosphate is one of the main raw materials for the production of lithium iron phosphate cathode materials, and its product quality will directly determine the electrochemical performance and processing performance of the final lithium iron phosphate product. (Wang Yanbin)
