  • Rechargeable battery
    Patent number: 9692032
    Abstract: A thin film is used in a metallic collector in order to increase the volume energy density. However, the strength of the thin film is low, so when a negative plate or a positive plate is directly joined to a terminal base portion, even an insignificant load might cause damage, such as cutting of the metallic collector. Even in a structure where the metallic collector is joined to a highly-conductive plate-like metal or a highly-conductive plate-like resin, and where the collecting plate is joined to a terminal base portion, the connection between the collecting plate and the terminal base portion affects the battery properties.
    Type: Grant
