Patent ID: 8486568

Claim:
A process for preparing an all-solid battery, comprising the steps of: forming a linear active material part by relatively moving a first nozzle which discharges an active material linearly with respect to a current collector to form a plurality of linear active material parts on the current collector, with spaces between each adjacent pair of said linear active material parts, forming a first electrolyte layer by relatively moving a second nozzle which discharges a first electrolyte material with respect to the current collector to apply the first electrolyte material to each of the plurality of the linear active material parts to form a respective linear electrolyte part thereon while maintaining said spaces therebetween, thereby to prepare a plurality of linear active material-electrolyte parts, photo-curing by irradiating light to the linear electrolyte parts to cure the same, and forming a second electrolyte layer by applying a second electrolyte material to the whole of the linear active material-electrolyte parts and to said spaces on the current collector between the linear active material-electrolyte parts to prepare said second electrolyte layer.
