A through-glass via-hole formation method includes: forming a hole-shaped deformed region extending in a thickness direction of a glass substrate by irradiating the glass substrate with a laser beam at an energy intensity not exceeding an ablation threshold of the glass substrate; and forming a via-hole through the glass substrate along the deformed region by immersing the glass substrate in an etching solution such that the deformed region is etched and removed, wherein an etching solution having a first concentration is used as the etching solution to allow the via-hole to have a first aspect ratio, and an etching solution having a second concentration greater than the first concentration is used as the etching solution to allow the via-hole to have a second aspect ratio smaller than the first aspect ratio.

Disclosed is method and device for forming an electrode plate. The method includes: performing tab cutting on a substrate so that the substrate forms a body portion, an edge portion connecting to the body portion, and a plurality of tabs that connect to the body portion but are separated from the edge portion; and performing edge portion cutting on the substrate to separate the edge portion from the body portion. The electrode plate is formed in two steps. First, the tab and the edge portion are separated, so that in the process of cutting, impact of vibration of the edge portion on the tab is small, greatly reducing the risk of deformation of the tab caused by vibration of the edge portion and damage to the tab caused by being pulled by the edge portion. Second, edge portion cutting separates the edge portion from the body portion.
