Abstract

The object of the present invention is to provide an electrode manufacturing method, a manufacturing device, and a battery. It is possible to suppress the reduction in battery performance during normal charging and discharging due to the increase in the internal resistance of the electrode, and at the same time to improve the overcharge characteristics, and to suppress the occurrence of deviation between the active material layers and the adhesion between the active materials. reduce, or increase manufacturing costs. Two active material layers ( 2, 3) In the electrode manufacturing method, the above-mentioned plurality of active material slurries are sequentially laminated and coated on the surface of the current collector in a wet state, and then all the active material slurries are dried.

Description

technical field

[0001] The present invention relates to a nonaqueous electrolyte battery such as a lithium ion battery or a polymer battery, a method for manufacturing an electrode used in the battery, and an apparatus for manufacturing an electrode used in the manufacturing method. Background technique

[0002] In recent years, mobile information terminals such as mobile phones, notebook personal computers, and PDAs have been rapidly reduced in size and weight, and batteries that serve as driving power sources have been required to have higher capacities. Nonaqueous electrolyte batteries, which are charged and discharged by moving lithium ions between the positive and negative electrodes along with charging and discharging, have high energy density and high capacity, and are therefore widely used as driving power sources for mobile information terminals as described above. In addition, the recent use of its characteristics is not limited to mobile office applications such a...
