Description
Technical field
The present invention relates to the alkaline battery that a kind of many drainages post carries out the heat exchange drainage.
Background technology
In order to satisfy operating voltage, the capacity requirement of EV (pure electric-powered car) or HEV (hybrid vehicle) battery modules, need a n shown in Figure 4 cell is combined into battery modules, the relative cooperation mutually of the broad side surface of the wider width of its battery housing, and the narrow side that the width of battery housing is narrower cooperatively interacts into a plane, separate with aluminium radiating fin or other materials between the broad side surface, 2 the battery broad side surfaces of outermost surface and the narrow side of all batteries clamp and are integral with metal tape.
Constituting of cell is equipped with the positive/negative plate group of confluxing in the battery housing, barrier film, electrolyte, on be covered with the safety valve sealing.Drainage thread constitutes from conflux group's the limit, upper end of each positive plate one side of positive/negative plate and upwards draws the drainage sheet, and its drainage sheet top connects positive electrode drainage post.Equally, upwards draw the drainage sheet from the limit, upper end of each negative plate one side, its drainage sheet top connects negative electrode drainage post.
The positive electrode drainage post of each cell of sealing and negative electrode drainage post adopt the nut series connection by striding pole piece, clamp with metal tape at battery housing broad side surface and the narrow side of all series-connected cells, the aluminium radiating fin forms heat dissipation channel between battery housing broad side surface, so that above-below direction forms heat exchanging medium passage, come each cell of heat exchange by cold wind.
But, in the structure of above-mentioned battery, be that each pole plate is confluxed group's the electronics of electrochemical reaction by conflux group's the drainage sheet of upper end of pole plate of each pole plate.Lead to pole.Because this kind drainage way is longer from pole plate whole the distance to the drainage sheet of group of confluxing, and causes the internal resistance of cell to increase, and the electric current distribution inequality, active material utilization is poor, thereby power output is low.In addition, because the internal resistance of cell increases, cause temperature rise speed to improve, the temperature difference aggravation between the pole plate makes that some active material produces phase transformation, oxidation in advance in the battery, finally causes battery to lose efficacy in advance.
Another kind of battery as shown in Figure 5, be that a plurality of battery pole plates with closed type secondary cell group of confluxing constitutes one mutually and forms a battery module between its narrow side, opening is with a lid integral sealing, with the collector plate of the metalwork connection both sides of running through narrow side between two cells above the cell that is separated.Above-mentioned novel secondary battery module is that conflux group and negative plate of positive plate confluxed left and right side drainage that the electronics of group electrochemical reaction passes through each pole plate to collector plate, and collector plate is welded to respectively on separately the drainage post.Shortened whole average distance of positive/negative plate to collector plate, reduced the internal resistance of cell, improved the utilance of electrode active material simultaneously, improved the fan-out capability of battery, but this kind structure is not improved the radiating rate and the temperature homogeneity of electrode pad and module from inside battery, battery is to be in series in same battery container by a plurality of batteries, because battery modules is to be applied to pure electric vehicle and hybrid electric vehicle, when the braking large current charge, because differing greatly of cell temperature, particularly the middle cell temperature of module is bigger with the edge temperature difference, causes charge acceptance inconsistent, and individual cell shifts to an earlier date the gassing phenomenon, after long-term the use, individual cell lost efficacy in advance, caused this module to lose efficacy, and can't repair.
Summary of the invention
The invention provides a kind of alkaline battery, it effectively reduces the internal resistance of battery and improves the power output of battery, simultaneously in built-up type secondary battery, the temperature homogeneity of each cell is improved, and effectively improves battery pack useful life.
