Analysis of the Current Market Status of Lithium Iron Phosphate Batteries

In the field of power batteries, there has always been controversy over the technological routes of ternary materials and lithium iron phosphate. China Battery Network found in a recent survey that today's technological roadmap is no longer the focus of attention for enterprises. Enterprises pay more attention to improving battery capacity density, improving processes, ensuring safety performance, and rapidly expanding production capacity to achieve more sharing. The dividends brought by the great development of the new energy vehicle industry.

On December 18, 2014, Tianjin Strand Energy Technology Co., Ltd. ("Strand") invested heavily to acquire 100% equity of Tianjin Yibirer Energy Technology Development Co., Ltd., ushering in the era of lithium battery cathode material acquisition in China. As one of the few companies in the world specializing in the production of phosphate series lithium cathode materials, the expansion of energy density and production capacity, as well as the reduction of production costs, of Stellan's positive power phosphate series lithium cathode materials.

At present, the annual production of lithium iron phosphate batteries in China is about 10000 tons, and it will continue to grow rapidly in the next few years. How to break through the patent dilemma and strive for more development space has become a concern for relevant enterprises at present.

Due to its inherent properties, lithium iron phosphate has low energy density, poor conductivity, relatively strict synthesis process, poor product stability control, and no significant price advantage, which greatly limits its current development. To address the weaknesses of this development, manufacturers should strengthen the research and development of key technologies from the perspective of improving performance, such as increasing conductivity through carbon coatings and doping to increase energy density.

The patent applications for lithium iron phosphate in China are mostly low-level repetitive studies. The overall research and development of lithium iron phosphate is still in the stage of foreign technology follow-up, lacking substantial innovation and major breakthroughs. Domestic enterprises should have a comprehensive understanding of the specific content of patents held by large foreign companies, bypass their patent scope, avoid patents, and search for gaps in patent technology to develop key independent knowledge. Intellectual property technology. While possessing patented technology, it is also necessary to strengthen the marketization of patents and avoid technology staying in the laboratory.
