Title:
ケイ素系またはスズ系アノード活性材料を含むリチウム二次電池
Document Type and Number:
Japanese Patent JP4541315
Kind Code:
B2
Abstract:
Provided is a lithium secondary battery comprising an anode mix including a silicon- or tin-based material as an anode active material, and as a binder, a photo-polymerizable material composed of one or more monomers selected from the group consisting of an epoxy derivative, polyester acrylate and epoxy acrylate, or oligomers or polymers thereof, wherein an anode can be prepared within a short period of time via a simplified manufacturing process by applying the anode mix to a current collector and polymerizing the applied anode mix with light-irradiation, and further, superior charge/discharge cycle characteristics of the battery are provided due to stable maintenance of binding between active materials and between the active material and current collector, regardless of significant volume changes of the anode active material occurring upon charging/discharging the battery.
