Nonaqueous secondary battery |
摘要 |
A nonaqueous secondary battery is disclosed, comprising a positive electrode sheet having on a current collector an electrode material mixture layer containing a lithium-containing transition metal oxide as a positive electrode active material, a negative electrode sheet having on a current collector an electrode material mixture layer containing a negative electrode material capable of intercalating and deintercalating lithium, and a nonaqueous electrolyte containing a lithium salt, wherein in at least one of said positive electrode sheet and said negative electrode sheet, in the case of the positive sheet, a layer containing no positive electrode active material is provided between plural electrode material mixture layers containing the positve electrode active material or between the electrode material mixture layer and the current collector; and in the case of the negative electrode sheet, a layer containing no negative electrode material capable of intercalating and deintercalating lithium is provided between plural electrode material mixture layers containing the negative electrode material or between the electrode material mixture layer and the current collector.
