Abstract

The invention discloses a novel storage battery, which comprises a shell; at least one polar plate group is arranged in the shell; the polar plate group consists of at least one polar plate; the polar plate group is soaked into electrolyte in the shell; an upper sealing cover for sealing the internal space of the shell is arranged above the shell; polar posts with positive and negative polarities are led out of the polar plate; the polar posts are connected to a bus bar; the polar plates in the polar plate group are connected in parallel together through the bus bar; the polar plate groups are connected in series together through the bus bars; a battery terminal is fixed on the bus bar; and the battery terminal bent for multiple times is led out of grooves on two sides of the upper sealing cover. Because the polar posts are connected by the bus bars in the novel storage battery, conductive posts are eliminated; all the bus bars are sealed in an encapsulation tank by adopting glue, so the storage battery has good sealing property and corrosion resistance; and the battery terminal is bent for multiple times, and labyrinth encapsulation design is adopted, so that the electrolyte cannot be leaked outwards through the battery terminal.

Description

A kind of novel storage battery

Technical field

The present invention relates to a kind of battery, particularly the good novel storage battery of a kind of airtight performance.

Background technology

In recent years, be accompanied by the development of various portable electric appts, as one of important Primary Component, researched and developed the storage battery of the hermetic type that becomes its driving power.The storage battery of existing hermetic type is to adopt at least one the pole plate group being immersed in electrolyte as power supply, and pole plate group is to be formed in parallel by polylith pole plate, and the outside post terminal guiding of pole plate welds together after the pole of the pole plate identical polar in same pole plate group converges; Multiple isolated pole plate groups are set in most storage battery, between these pole plate groups, adopt and be connected in series, after in same pole plate group, the pole of identical polar converges, conductive pole in welding, between adjacent plate group, the conductive pole of opposed polarity is connected, each pole plate group is together in series, and between conductive pole, connection adopts the embedding of environmental protection glue that different pole plate set isolations are come simultaneously; Be positioned on the conductive pole of opposed polarity at two ends and be welded with battery terminal, the through hole that battery terminal upwards directly has through upper cover is drawn out to outside battery, and the through hole that is potted in upper cover by environmental protection glue secondary prevents battery leakage.Because conductive pole and battery terminal are generally to adopt lead to be made, the conductive pole of existing sealed rechargeable battery and battery terminal long period of soaking are in electrolyte, can be corroded and attenuate, electrolyte in battery is easily leaked out by the conductive pole attenuating and battery terminal place, and the need of production of sealed rechargeable battery seals through twice encapsulating, complex production process, cost is high.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides the novel storage battery that a kind of airtight performance is good, can effectively prevent the phenomenon of leakage of sealed rechargeable battery, and manufacture craft is simple, cost is low.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of novel storage battery, comprise housing, in housing, be provided with at least one pole plate group, pole plate group is made up of at least one pole plate, pole plate group is immersed in the electrolyte in housing, housing top is provided with the upper cover for enclosure space, described pole plate is outwards derived the pole of both positive and negative polarity, described pole is connected to bus-bar, pole plate in pole plate group is connected in parallel by bus-bar, between pole plate group, be cascaded by bus-bar, on described bus-bar, be fixed with battery terminal, described battery terminal is repeatedly drawn from the groove of upper cover both sides after bending.

One as technique scheme is improved, and is provided with the dividing plate that enclosure interior spatial separation is become at least two not connected groove positions in described housing, and in each groove position, correspondence is placed with one group of pole plate group, and different pole plate set isolations is placed in different groove positions.

Improve as the one of technique scheme, the corresponding each groove of described upper cover position is provided with liquid injection hole, liquid injection hole be provided for the fluid injection in battery production process and battery is long-time after using fluid infusion.

One as technique scheme is improved, and is provided with the little dome for capping liquid injection hole on described upper cover, and roundlet lid is sealed on liquid injection hole, prevents leakage.

One as technique scheme is improved, and described liquid injection hole top is installed with overhead gage, and the little dome on protection liquid injection hole is difficult for being opened, and further prevents battery leakage.

One as technique scheme is improved, and described upper cover bottom is provided with encapsulation groove, and described bus-bar adopts epoxy glue to be sealed in encapsulation groove.

One as technique scheme is improved, and described housing both sides are provided with resistance to compression groove, improves the anti-pressure ability of battery.

The invention has the beneficial effects as follows: this novel storage battery due to adopt bus-bar pole is coupled together, saved the use of conductive pole, and bus-bar all adopt glue be potted in encapsulation groove in, good airproof performance, anticorrosive; Repeatedly bending of battery terminal simultaneously, adopts labyrinth type package design, makes electrolyte can not pass through battery terminal leakage outward.
