PREPARATION METHOD OF LITHIUM POLYMER BATTERY

摘要

PURPOSE: A method for preparing a lithium polymer battery is provided, to improve the energy density of an electrode plate and to reduce the internal resistance compared with the case using lithium metal oxide and to improve the reaction area and the reaction velocity compared with the case using lithium metal, thereby enhancing the charging/discharging efficiency. CONSTITUTION: The method comprises the steps of dissolving a polymer binder into a solvent to a prepare a binder solution; adding lithium powder with a size of 10-50 micrometers and a conductive material into the binder solution to prepare an electrode slurry; coating a current collector with the electrode slurry and drying it to prepare an electrode; and adding graphite which is an active material of the other electrode, with the electrode into an aluminum laminate film and injecting an organic solvent to seal it.
