Title:
MANUFACTURING METHOD OF NONAQUEOUS ELECTROLYTE LITHIUM SECONDARY BATTERY AND CONDITIONING METHOD OF NONAQUEOUS ELECTROLYTE LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2016045998
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a high-voltage nonaqueous electrolyte lithium secondary battery, capable of reducing initial battery resistance.SOLUTION: A manufacturing method of a nonaqueous electrolyte lithium secondary battery includes: a step of manufacturing a power generation unit including a positive electrode mixture layer containing LiBOand a positive electrode active material having a charge/discharge region at 4.6 V or more on the basis of Li; and a conditioning step of changing/discharging the power generation unit having been manufactured. In the manufacturing method, the upper limit voltage during the conditioning step is the decomposition voltage of LiBO.SELECTED DRAWING: Figure 1
