Method of manufacturing a battery

Abstract

To provide a method of manufacturing a battery capable of enhancing productivity and preventing deterioration of the battery performance. After attaching a positive electrode terminal to a belt-shaped electrode, electrolyte layers are formed. This can decrease the number of manufacturing processes after forming electrolyte layers, which effectively prevents that solvents in the electrolyte evaporates or the electrolyte layers are absorbed the water. Thereby, manufacturing yields of the battery can be enhanced, Additionally, a battery excellent in discharge capabilities and stable in voltage can be attained.

         18 . A method of manufacturing a battery comprising: 
 a) forming an electrode mixture layer including electrode active material on a first region but not on an exposed region of an electrode collector, wherein the first region is formed with an electrolyte layer, and wherein the electrode collector is cut between the electrode mixture layer which is intermittently formed;    b) attaching a terminal to the exposed region, wherein the electrode mixture layer is not formed on the exposed region between the attaching of the terminal and the forming of the electrode mixture layer; and    c) disposing a protection tape in a manner of covering a part of the terminal after the terminal is attached to the electrode collector exposed region, 
 wherein the electrolyte is delivered in a state where the electrolyte is heated for adjusting its viscosity in the range of 0.001 Pa•s to 0.005 Pa•s during a formation of the first region of the electrode collector.
