Problems solved by technology

[0002] During the charging and discharging process, the positive and negative plates in the battery plate group will undergo side reactions to electrolyze water to precipitate gas, generate heat and volume expansion, etc. , eventually forming a dry phenomenon, which makes the active material in the middle of the plate group inactive and terminates its life.
The above defects limit the service life of the battery and the expansion of the application field.

Embodiment

[0027] Such as Figure 1-7 As shown, a spring plate used in the battery plate group, the spring plate is arranged on one side or both sides of the pole plate group or between single or multiple adjacent pole plates 1 in the pole plate group, the spring plate The plate plane is porous, and the spring plate has springs or shrapnels that can automatically adjust the height according to the pressure. The spring board is made of elastic material, hollow plastic or corrugated plastic, or the spring board is partially punched or processed from an elastic steel plate.

[0028] The spring plate is a uniform multi-opening spring plate 2, a punched hollow plate 3 or a corrugated spring plate 4, and the spring plate is provided with at least one for discharging the precipitated gas of the plate and adding electrolyte and overlapping with the through hole of the plate. through-hole 5.

[0029] When the elastic plate is a uniform multi-opening elastic plate 2, a single uniform multi-openi...

Abstract

The invention discloses an elastic plate used for a battery plate set, wherein the elastic plate plane has holes, and the elastic plate has springs or elastic plates capable of automatically adjustingthe height according to the pressure magnitude, and the springs or elastic plates are arranged on one side of the elastic plate to form an elastic plate with uniformly distributed holes and uniformlydistributed multiple springs or elastic plates. The invention realizes that the precipitated gas can be rapidly discharged by utilizing the gap, replenish the required electrolyte and provide a fastcooling channel inside the pack, and can automatically adjust the thickness of the electrode plate group according to the expansion force of the electrode plate group, so as to maintain a certain degree of tightness of the electrode plate group, effectively improve the anti-drying ability of the gas precipitated in the electrode plate group and supplement the electrolyte, thereby achieving the purpose of prolonging the service life of the battery.

Description

technical field [0001] The invention belongs to the technical field of spring plates, and in particular relates to a spring plate used in battery pole plate groups, which is beneficial to gas separation, liquid replenishment, heat dissipation and anti-swelling. Background technique [0002] During the charging and discharging process, the positive and negative plates in the battery plate group will undergo side reactions to electrolyze water to precipitate gas, generate heat, and expand in volume. , and finally form a dry phenomenon, so that the active material in the middle of the plate group loses its activity and its life ends. The above defects limit the service life of the storage battery and the expansion of the application field. Contents of the invention [0003] The technical problem solved by the present invention is to provide a spring plate used in the battery plate group, which can quickly discharge the precipitated gas by using the gap, replenish the require...
