CATHODE, CATHODE-CONTAINING LITHIUM ION BATTERY IN THE STATE PRIOR TO THE FIRST CHARGING PROCESS, METHOD FOR FORMING A LITHIUM ION BATTERY, AND LITHIUM ION BATTERY AFTER FORMATION

摘要

The invention relates to a cathode in the state prior to the first charging process (formation), comprising active cathode material and lithium peroxide. The invention further relates to a lithium battery or an electrochemical cell comprising the cathode, to a method for forming the lithium battery, and to a lithium ion battery with a cathode comprising active cathode material, a separator, an anode comprising active anode material, and an electrolyte, wherein after a formed cell is fully discharged, the active cathode material has virtually the same lithium content as before the formation process.
