  • Patent number: 9761906
    Abstract: A main object of the present invention is to provide a method for manufacturing a sulfide solid electrolyte that enables a sulfide solid electrolyte whose ion-conducting characteristic is easy to be improved, to be manufactured. The present invention is a method for manufacturing a sulfide solid electrolyte including loading a raw material for manufacturing a sulfide solid electrolyte which is mainly composed of a substance represented by the general formula of (100?x)(0.75Li2S.0.25P2S5).xLiI (here, 0<x<100), into a vessel; and amorphizing the raw material after said loading, wherein a reaction site temperature in the vessel is controlled so that x included in the general formula and the reaction site temperature y [° C.] in the vessel in said amorphizing satisfy y<?2.00x+1.79×102.
    Type: Grant

  • Patent number: 9157964
    Abstract: Disclosed is method for producing a secondary battery, capable of selection of a secondary battery having a defect caused by a micro short-circuit with high accuracy. A step for producing a secondary battery includes an inspection step for selecting the secondary battery having the defect among multiple secondary batteries. In the inspection step, a short circuit resistance is calculated based on capacitances of the multiple secondary batteries calculated before self-discharge inspection, a time required for the self-discharge inspection, first and second reference voltages calculated from open circuit voltages measured before and after the self-discharge inspection in the multiple secondary batteries, and first and second voltages which are open circuit voltages of one selected from the multiple secondary batteries measured before and after the self-discharge inspection.
