Original Abstract Submitted
The present application provides a secondary battery and a power consuming device. The secondary battery comprises a negative electrode plate, wherein the negative electrode plate comprises a negative electrode current collector and a negative electrode film layer formed on at least one surface of the negative electrode current collector, the negative electrode film layer has a first surface away from the negative electrode current collector and a second surface opposite to the first surface; the first area comprises a first active material, the first active material comprises a first carbon-based material, and the first carbon-based material has a pore structure; and the second area comprises a second active material, and the second active material comprises a second carbon-based material. The present application enables the secondary battery to have not only a high energy density but also high safety performance, and good dynamic performance, cycling performance and storage performance.
