ELECTROCHEMICAL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18246290 titled 'ELECTROCHEMICAL DEVICE
Simplified Explanation
The abstract describes an electrochemical device that includes a positive electrode, a negative electrode, and a separator. The negative electrode has a negative current collector and a negative electrode mixture layer containing a material that can be reversibly doped with lithium ions. The negative current collector has no through-hole and the specific surface area of the negative electrode mixture layer is between 30 m/g and 60 m/g. In a discharged state, the potential of the negative electrode is less than or equal to 0.2 V with respect to a Li counter electrode.

Original Abstract Submitted
An electrochemical device includes: an electrode body including a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode; and an electrolyte containing a lithium salt. The negative electrode includes a negative current collector and a negative electrode mixture layer supported on the negative current collector. The negative electrode mixture layer contains a negative electrode active material that is reversibly doped with lithium ions, and the negative current collector has substantially no through-hole. A specific surface area of the negative electrode mixture layer is in a range from 30 m/g to 60 m/g, inclusive, and in a discharged state, a potential of the negative electrode is less than or equal to 0.2 V with respect to a Li counter electrode.
