THE NON-AQUEOUS AND HIGH-CAPACITY LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a method of preventing lithium dendrite on a negative electrode of a non-aqueous lithium secondary battery, and the non-aqueous lithium secondary battery using the same. The present invention provides a production method of the non-aqueous lithium secondary battery by forming the battery using a high capacity positive electrode active material with high contents of lithium and a lithium metal negative electrode active material, wherein the negative electrode active material includes a foam type lithium structure, and the foam type lithium structure is produced by spreading lithium on a foam type metal structure.
