Abstract
The utility model discloses a nickel-metal hydride battery plate structure which is used for solving problems that an existing nickel-metal hydride battery has relatively concentrated output current, large internal resistance, and the like. According to the utility model, the other surface on the upper part of a polar plate (2) is connected with one part of another tab (1), so that tabs (1) at the two sides of the polar plate (2) are symmetrically arranged, and the nickel-metal hydride battery plate structure has the advantages that battery output current distribution is uniform, internal resistance is small, the charging-discharging rate and the safety of a battery are improved, and the like.
Description
Technical field
The utility model relates to a kind of battery pole plates structure, relates in particular to a kind of Ni-MH battery electrode plate structure being made up of pole plate and lug.
Background technology
The advantages such as Ni-MH battery has high-power, and high power capacity is pollution-free, fail safe height are subject to the favor of every profession and trade.The current developing direction of Ni-MH battery is to the development of motive use type, requires it to have better high rate during charging-discharging, higher power and better security performance.The high rate during charging-discharging that improves battery will reduce the internal resistance of battery, because under same voltage, the internal resistance of resistance is lower, the discharging current that can reach is larger, on the other hand, the high internal resistance meeting of battery makes sharply to rise in temperature short time of inside battery, reduce the fail safe of battery, the performance of battery itself is impacted simultaneously, moreover because the internal resistance of battery is large, cause the ohm voltage drop of battery to become large, when battery discharge, can must drop to sooner cut-ff voltage, battery capacity can not be fully utilized.The internal resistance of cell, together with the resistance sum between all substances of both positive and negative polarity, comprises the interface impedance of positive plate impedance, negative plate impedance, positive pole ear impedance, negative lug impedance, electrolyte impedance and pole piece and electrolyte.Generally, the performance of improving battery is all that the performance that aligns negative electrode active material is improved, and seldom has to improve to reach for the manufacturing process of battery to improve battery performance.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy operating, and battery current is evenly distributed, internal resistance diminishes, and improves the charge-discharge magnification of battery, and improves the Ni-MH battery electrode plate structure of the fail safe of battery.
For achieving the above object, a kind of Ni-MH battery electrode plate structure of the utility model, comprises pole plate and lug, and pole plate top one side is connected with lug is a part of, and described pole plate top another side is connected with another lug is a part of, and the lug on pole plate both sides is symmetrical set.
Between lug, connect by electric welding.
Between lug, connect by electric conductor.
Adopt after this structure, be connected because described pole plate top another side and another lug are a part of, the lug on pole plate both sides is symmetrical set; Between lug, connect by electric welding; Between lug, connect by electric conductor.Therefore, reach simple in structure, easy operating, and battery current is evenly distributed, internal resistance diminishes, and improves the charge-discharge magnification of battery, and improves the object of the fail safe of battery.
accompanying drawing explanationbelow in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is that the master of a kind of Ni-MH battery electrode plate structure of the utility model looks schematic diagram.
In figure: 1. lug 2. pole plates.
embodimenta kind of Ni-MH battery electrode plate structure of the utility model shown in accompanying drawing 1, comprise pole plate 2 and lug 1, pole plate 2 top one sides are connected with lug 1 is a part of, and described pole plate 2 top another sides are connected with another lug 1 some, and the lug 1 on pole plate 2 both sides is symmetrical set; Between lug 1, connect by electric welding; Between lug 1, connect by electric conductor.
Claims (3)
1. a Ni-MH battery electrode plate structure, comprise pole plate and lug, pole plate top one side is connected with lug is a part of, it is characterized in that: described pole plate (2) top another side is connected with another lug (1) is a part of, and the lug (1) on pole plate (2) both sides is symmetrical set.
2. a kind of Ni-MH battery electrode plate structure according to claim 1, is characterized in that: lug connects by electric welding between (1).
