The utility model relates to a kind of Double-pole lug secondary battery, comprise positive plate, negative plate and glass fibre separator, separate with glass fibre separator between positive plate and negative plate, positive plate is provided with two anode ears on the same side, negative plate is provided with two negative electrode lugs on the same side, and the anode ear after the pole group of positive plate and negative plate composition and negative electrode lug are oppositely arranged.The utility model Double-pole lug secondary battery in use, the direction of the charging and discharging currents of positive plate and negative plate changes, CURRENT DISTRIBUTION on pole plate is balanced, thus effectively improve the situation of large current density electrode column heating, improve the utilance of the active material of pole plate, greatly extend the useful life of storage battery.
Description
Technical field
The utility model relates to a kind of storage battery, particularly a kind of Double-pole lug secondary battery.
Background technology
Storage battery on market, no matter be acid cell or alkaline battery, inside battery pole group comprises positive plate, negative plate and glass fibre separator, separate with glass fibre separator between positive plate and negative plate, the conducting of battery positive plate negative plate can be prevented and short circuit, positive/negative plate all only has a square lug, and the lug after positive plate and negative plate composition pole group is in the same side.The storage battery of this extreme ear structure has many defects: because lug is when the same side, positive pole top and bottom, the position difference of negative pole top and bottom and lug, when the side's of filling point, it is uneven to there is matter utilization in the top and the bottom of pole plate, and CURRENT DISTRIBUTION is uneven, concentration of electrolyte skewness, battery uses the density of electrolyte of bottom after a period of time higher than the density of electrolyte on battery top, the utilance of the active material of pole plate can be caused to decline, have a strong impact on the useful life of storage battery.The storage battery of this kind of structure can not carry out discharge and recharge by big current, because electric current is excessive, internal resistance sharply increases, and pole is generated heat thus damages storage battery.
Summary of the invention
When the technical problems to be solved in the utility model is to provide a kind of impulse electricity, the CURRENT DISTRIBUTION balance on pole plate, when effectively improving high current charge-discharge, the using state of storage battery, improves the utilance of active material, extends the useful life of storage battery.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of Double-pole lug secondary battery, comprise positive plate, negative plate and glass fibre separator, separate with glass fibre separator between positive plate and negative plate, battery positive plate and negative plate conducting can be prevented and short circuit, it is characterized in that positive plate is provided with two anode ears on the same side, negative plate is provided with two negative electrode lugs on the same side, and the anode ear after the pole group of positive plate and negative plate composition and negative electrode lug are oppositely arranged.
Further, positive plate, negative plate can be horizontally disposed with, this set is more conducive to positive plate, negative plate CURRENT DISTRIBUTION balance when charge and discharge, make the concentration that the concentration of electrolyte in whole storage battery reaches unified, there will not be the phenomenon that the concentration of electrolyte of storage battery top and the bottom is inconsistent, thus significantly improve the useful life of storage battery.
Certainly, in order to the needs installed and use, the shape of positive and negative lug can be set to square, circular and oval.
Adopt said structure, the direction of the positive pole of storage battery and the charging and discharging currents of negative pole changes, be from side to opposite side, current flowing on pole plate is balanced, is evenly distributed, thus effectively improve the situation of large current density electrode column heating, the uniform concentration distribution of storage battery electrolyte inside simultaneously, there is not concentration difference, improve the utilance of the active material of pole plate, greatly extend the useful life of storage battery.
