- 鋰電池石墨負極包覆材料Coating Material for Graphite Based Anode of Lithium-ion Batteries
- 鋰電池負極材料目前以石墨為主，石墨負極材料表面不易形成穩定的SEI膜，且易剝離，對電池性能產生不利影響。 奧億達的表面瀝青包覆材料可以幫助負極形成薄而致密、穩定的SEI膜，提升首充效率、改善循環性能及倍率性能。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.
- 鋰電池硅碳負極包覆材料Coating Material for Silicon-carbon Composite Anode of Lithium-ion Battery
- 硅基負極是新一代鋰電材料，與石墨相比，其具有更高的比容量與更長的使用壽命。硅碳負極包覆可提升碳材料對硅材料的親和性，提升負極材料性能，并有效控制硅負極的膨脹系數。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.
