Abstract
A composite lithium secondary battery, and the core assembly of the secondary battery includes: at least one positive electrode layer, at least one negative electrode layer and a plurality of separating layers which are superimposed one another and rolled up to form the core assembly. The positive electrode layer is provided with a plurality of coating sections and at least one non-coating section. The coating sections are coated with different positive electrode materials which are separated from one another by the non-coating section. At least one coating section on each of the two opposite surfaces of the positive electrode layer is coated with a different positive electrode material than other coating sections. The positive electrode materials are LFP and lithium-containing ternary oxides, so that, during the process of charge and discharge, the lithium secondary battery would have the advantages of different positive electrode materials.
