Cathode (positive electrode) and this comprehensive lithium ion battery in the state before the first charging, method for forming a lithium-ion battery and lithium ion battery after formation

摘要

The invention relates to a cathode in the state before the first charging (formation) comprising active cathode material and lithium peroxide. Furthermore, the invention relates to a lithium battery or electrochemical cell comprising the cathode, a method for forming the lithium battery and a lithium-ion battery with cathode comprising cathode active material, separator, anode comprising anode active material and electrolyte, wherein the cathode active material after almost completely discharging a formed cell same lithium content as before the formation.
