The grid is the main component of the lead-acid battery and the current collecting skeleton of the electrode. It conducts and collects the current and makes the current distribution uniform. At the same time, it supports the active material and is the carrier of the active material. When lead-acid batteries are charged and discharged, the density of active substances will change. That is, the density of the active material before and after conversion is different, so when discharging, the molar volume of the active material will increase, and the electrode plate will expand and deform, while during charging, the volume of the active material will decrease, that is, the electrode plate will shrink. The support can prevent the active material from falling off due to expansion and contraction of the electrode plate.

There are two main types of grids: drawing and casting. Casting is to pour the heated and melted lead alloy into the grid mold under the action of gravity, and it is processed after cooling and forming. The stretched mesh grid is formed by drawing a certain width of lead tape on a punching machine to make a prescribed rectangular hole and forming it by stretching.
