METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

Japanese Patent JP2014130729

A

PROBLEM TO BE SOLVED: To provide a method for manufacturing a nonaqueous electrolyte secondary battery in which a material derived from a charge carrier is suppressed from being precipitated by forming a coat of a more preferable mode on the surface of a negative electrode active material.SOLUTION: A manufacturing method of the present invention includes: a step (S10) of preparing a positive electrode and a negative electrode, while a sodium component is contained, as inevitable impurities, in at least the negative electrode; a step (S20) of forming an electrode body using the prepared positive electrode and the negative electrode; a step (S30) of forming an assembly including the electrode body accommodated within a battery case; a first injecting step (S40) of injecting a nonaqueous solvent having a dielectric constant of 10 or less into the battery case; a second injection step (S50) of, after the first injection step, injecting a nonaqueous electrolyte containing a lithium bis(oxalato)borate into the battery case; and a step (S60) of performing initial charge of the assembly.
