Japanese Patent JP7357690

B2

The present application discloses a composite current collector, an electrode plate and an electrochemical device. The composite current collector includes an organic support layer and a metal conductive layer disposed on at least one surface of the organic support layer; and the composite current collector has a brittleness parameter C of 0.01 ≤ C ≤ 0.5. The composite current collector provided by the present application has relatively high mechanics and mechanical properties which having good electrical conductivity and current collection performance, which can improve preparation yield of the composite current collector, the electrode plate and the electrochemical device and their reliability during use, and enables the electrochemical device to have relatively high electrochemical performance and gravimetric energy density.
