Abstract
is reported as an anode material for lithium-ion batteries. Graphene nanosheets form a sea-like, highly electronically conductive matrix, where the island-like phosphorus particles are dispersed. Benefiting from this structure and properties of phosphorus, the hybrid delivers high initial capacity and exhibits promising retention at 60 °C.
摘要
据报道，它是一种用于锂离子电池的负极材料。石墨烯纳米片形成一种海状的、具有高电子导电性的基体，岛状的磷颗粒分散在其中。得益于磷的这种结构和性能，这种复合材料具有高初始容量，并在60℃时表现出良好的容量保持率。
