我国磷系新能源电池材料研究现状与展望

Research status and prospects of phosphorous based new energy battery materials in China

新能源是决定我国先进制造业竞争力的战略性领域,是先进生产力的标志,而磷化工产业是新能源的重要基础。为了打造高端磷化工产业,大力发展绿色新能源板块,促进磷化工产业与新能源产业之间的交叉耦合与横向多元发展,加强磷系新能源材料研究非常重要。本文综述了我国磷化工行业发展现状和磷系新能源电池材料的研究现状。磷酸盐正极复合材料、单质磷或金属磷化物负极复合材料可以解决目前新能源电池存在的导电性差、比容量低、循环稳定性差等问题。我国应依托现有基础化学品磷、磷酸,努力提升磷化工产品的附加值,其中高端磷系新材料是磷化工绿色发展的主要方向。

New energy is a strategic field that determines the competitiveness of China’s advanced manufacturing industry,and it is a sign of advanced productivity.The phosphorus chemical industry is an important foundation for new energy.In order to build a high-end phosphorus chemical industry,vigorously develop green new energy plates,and enhance the cross-coupling and horizontal multiple development between the phosphorus chemical industry and the new energy industry,strengthening the research on phosphorus based new energy materials is very important.This article summarizes the current development status of China's phosphorus chemical industry and the research status of phosphorus based new energy battery materials.Phosphate positive composite materials,elemental phosphorus or metal phosphates negative composite materials solve the current new energy batteries have poor conductivity,low specific capacity,poor cycle stability and other problems.China should rely on the existing basic chemicals phosphorus and phosphoric acid,and strive to improve the added value of phosphorus chemical products,among which high-end new phosphorus materials are the main direction of green development of phosphorus chemical industry.
