锂电池石墨负极包覆材料Coating Material for Graphite Based Anode of Lithium-ion Batteries: 锂电池负极材料目前以石墨为主，石墨负极材料表面不易形成稳定的SEI膜，且易剥离，对电池性能产生不利影响。奥亿达的表面沥青包覆材料可以帮助负极形成薄而致密、稳定的SEI膜，提升首充效率、改善循环性能及倍率性能。Currently, graphite is mainly used as the anode materials for lithium-ion batteries. However, the surface of graphite anode is not easy to form a stable SEI membrane and is prone to detachment, which has an adverse effect on the battery performance. AYD's surface pitch coating materials can help the anode to form a thin, dense, and stable SEI membrane, which can improve the initial charge efficiency, cycle performance, and performance of the battery.
锂电池硅碳负极包覆材料Coating Material for Silicon-carbon Composite Anode of Lithium-ion Battery: 硅基负极是新一代锂电材料，与石墨相比，其具有更高的比容量与更长的使用寿命。硅碳负极包覆可提升碳材料对硅材料的亲和性，提升负极材料性能，并有效控制硅负极的膨胀系数。Silicon-carbon composite anode is a new material for lithium-ion batteries. Compared with graphite, it has higher specific capacity and longer cycle life. Coating of the silicon-carbon composite anode can improve the compatibility between the carbon material and the silicon material, enhance the performance of the anode, and effectively control the expansion of the silicon anode.
