Title:
非水電解質二次電池
Document Type and Number:
Japanese Patent JP6545702
Kind Code:
B2
Abstract:
A nonaqueous electrolyte secondary battery includes a positive electrode including a positive electrode mix layer, a negative electrode, and a nonaqueous electrolyte. The positive electrode mix layer contains a lithium transition metal oxide containing zirconium (Zr) and also contains a phosphate compound. The nonaqueous electrolyte contains a linear carboxylate. According to this configuration, the nonaqueous electrolyte secondary battery, which has excellent low-temperature output characteristics, can be provided. Thus, the nonaqueous electrolyte secondary battery is, for example, a power supply for driving a mobile data terminal such as a mobile phone, a notebook personal computer, a smartphone, or a tablet terminal and is particularly suitable for applications needing high energy density. Furthermore, the nonaqueous electrolyte secondary battery is conceivably used for high-output applications such as electric vehicles (EVs), hybrid electric vehicles (HEVs), and electric tools.
