According to the utility model, the positive plates, the partition paperboards and the negative plates are horizontally stacked so as to avoid the swelling deformation of the storage battery; therefore, uniform full reactions of diachylon on the positive plates and the negative plates are facilitated, the cycle life of the storage battery is prolonged by 30%, the large-current discharge performance is improved by 15%, and the discharge capacity of the storage battery is increased by 10%.

Description

Flat-stacked high-performance battery

technical field

The utility model relates to a storage battery, in particular to a flat-stacked high-performance storage battery.

Background technique

Conventional battery stacking method is vertical stacking. The disadvantages are: as the battery is used for a long time, its electrolyte will gradually decrease. The expansion in the lamination direction causes the plastic shell to gradually bulge and deform, and eventually it cannot be used.

Secondly, the directions of the positive and negative lugs are on the same side, and the lead-out of the bus bar is also on the same side. The lead paste on the (upper) board surface close to the bus bar has a high utilization rate, and the lead paste on the board surface (lower part) far from the bus bar is higher. The paste utilization rate is low, so the lead paste on the upper board surface is easily softened and peeled off if it is used too much. Although the lower part is not used highly, the charging acceptance is also small, so long-term undercharging may easily cause the lead paste to be sulfated and become invalid. So the battery life is short.

Utility model content

The purpose of this utility model is to provide a flat-stacked high-performance storage battery with long service life, high battery capacity and strong high-current discharge performance for the above-mentioned existing problems and deficiencies.

A flat-stacked high-performance storage battery, comprising a case, positive plates and negative plates horizontally stacked in the case, paper separators arranged between adjacent positive plates and negative plates, and a battery cover, the There are vertical slots 1 and 2 protruding from the corresponding two side walls of the housing, and the tabs of the positive plate and the negative plate are respectively arranged on the opposite sides, and are connected by bus bars. In the first slot and the second slot, the upper cover is provided with a valve hole, a positive terminal and a negative terminal.

The shape of the positive electrode plate and the negative electrode plate is a regular polygon such as a square, a regular hexagon, or a rectangle or a circle.

Adopt above-mentioned technical scheme, the beneficial effect that obtains is:

The stacking method of the positive plate, the paper separator and the negative plate of the utility model is to overlap horizontally to avoid battery swelling and deformation; positive and negative plates are placed symmetrically across each other, and the busbars are drawn out symmetrically, which is beneficial to the uniform and sufficient reaction of the lead paste on the plate, and at the same time It also suppresses the failure of the lead paste at the ear part too quickly, prolongs the cycle life of the battery by 30%, improves the high-current discharge performance by 15%, and increases the battery discharge capacity by 10%. It is ribbed, and the strength of the shell is increased to ensure that the side wall will not be bulged and deformed.

Detailed ways

Below in conjunction with accompanying drawing, the specific implementation of the present utility model is described in detail.

Referring to Fig. 1 and Fig. 2, a flat-stacked high-performance storage battery includes a casing, 1, a positive electrode plate 2 and a negative electrode plate 3 arranged horizontally and staggered in the casing 1, and adjacent positive electrode plates 2 and negative electrode plates 3 between the cardboard 5 and the battery cover 6, the corresponding two side walls of the housing 1 protrude outwards with vertical slots 1 8 and 2 9, the positive plate 2 and the The tabs 4 of the negative plate 3 are arranged on opposite sides respectively, and are respectively arranged in the first channel 8 and the second channel 9 through the bus bar 7. The upper cover 6 is provided with a valve hole 12, a positive terminal 10 and a The shape of the negative terminal 11, the positive plate 2 and the negative plate 3 is a regular polygon such as a square, a regular hexagon, or a rectangle or a circle.

The stacking method of the positive plate, the paper separator and the negative plate of the utility model is to overlap horizontally to avoid battery swelling and deformation; positive and negative plates are placed symmetrically across each other, and the busbars are drawn out symmetrically, which is beneficial to the uniform and sufficient reaction of the lead paste on the plate, and at the same time It also suppresses the failure of the lead paste at the ear part too quickly, prolongs the cycle life of the battery by 30%, improves the high-current discharge performance by 15%, and increases the battery discharge capacity by 10%. It is ribbed, and the strength of the shell is increased to ensure that the side wall will not be bulged and deformed.
