Abstract

The invention provides a battery capable of suppressing expansion of a battery cell and a method for manufacturing the same. A battery (1) is provided with an electrode assembly including a positive electrode plate (210), a negative electrode plate (220), and a separator (230) disposed between the positive electrode plate (210) and the negative electrode plate (220). A first adhesive layer (241) is provided between the positive electrode plate (210) and the separator (230), and a second adhesive layer (242) is provided between the negative electrode plate (220) and the separator (230). The weight per unit area of the first adhesive layer (241) is smaller than the weight per unit area of the second adhesive layer (242), and the total of the weight per unit area of the first adhesive layer (241) and the weight per unit area of the second adhesive layer (242) is 0.03 g / m2 or more and 0.15 g / m2 or less.

Description

technical field [0001] The present invention relates to a battery and a manufacturing method thereof. Background technique [0002] Conventionally, a battery is known that includes an electrode body including a positive electrode plate, a negative electrode plate, and a separator disposed between the positive electrode plate and the negative electrode plate, and provided between the electrode plates (positive electrode plate and negative electrode plate) and the separator adhesive layer. [0003] In the electrode body, if the adhesive force between the electrode plate (especially the positive electrode plate) and the separator is too strong, the gap between the electrode plates may not be sufficiently vacated in the drying process of the battery cell, and it may not be possible to properly ensure the The path through which the battery cell drains moisture. In this case, the residual moisture reacts with the electrode active material to generate gas, and the battery cell te...
