| A method for separating the electrode material composition from the metal substrate in a lithium-ion battery involves immersing the battery electrode in a chelation solution maintained at a temperature between 20℃ and 30℃ for a duration of at least 40 minutes. The battery electrode consists of a metal substrate coated with an electrode material composition. The chelation solution, with a pH ranging from 6 to 9, contains both a chelating agent and a pH-adjusting agent, which are distinct substances. This method offers benefits such as energy efficiency and environmental sustainability while preserving the integrity of the electrode material composition, ensuring no damage occurs during the separation process. |
