In the following description, (this is because rechargeable Ni-MH battery group has obtained using widely although be illustrated as illustrated example easily with ni-mh (NiMH) battery pack, and known its has splendid power density properties, and reasonable price, battery life are moderate), but those skilled in that art it will be appreciated that, be without loss of generality, the principle of this declarative description is done to may be used on after necessary the correction in other type (comprise with parallel stacked battery lead plate battery) prismatic batteries, in the particularly rechargeable prismatic batteries.
Usually, battery module comprises a plurality of batteries that link together, and reaches suitable rated power requirement.Each battery all comprises electrode plate groups 10, and this electrode plate groups 10 is formed by the positive and negative electrode plate of the parallel plant of a pile, and separator is plugged between the adjacent electrode plates and (in general, is " electrode plate groups ").Electrode plate groups comprises the positive electrode plate group and the negative electrode plate group of being separated by separator.The positive electrode plate group comprises that a plurality of front portions are connected to the positive electrode plate on the positive current-collector.The negative electrode plate group comprises that a plurality of front portions are connected to the negative electrode plate on the negative current-collector.Positive and negative electrode plate group constitutes the electrode plate groups of prismatic batteries together.Electrode plate groups is arranged such that positive electrode plate and negative electrode plate align by being plugged in whenever, the separator between the negative electrode plate interlocks.
Each battery lead plate all comprises conversion zone and the zone of leading.The respective reaction zone of a pair of positive and negative plate is roughly overlapping, and reacts existing under the electrolytical situation, thereby chemical energy is converted into electric energy.The conversion zone of the battery lead plate of typical prismatic batteries is roughly rectangle, and one in its longer side or the vertical side is near leading parts.This part of leading is normally elongated, and with the length of vertical side of conversion zone about equally and be roughly rectangle so that the efficient maximum.Certainly, leading part can be shorter or longer.The rectangular active regions of battery lead plate is made by identical basic material usually, and conversion zone and lead the part the two have roughly the same length.Certainly, it should be noted that conversion zone is rectangle normally, but must be so, and be without loss of generality, the conversion zone of other shape can be adopted.
In typical rechargeable Ni-MH battery group, the conversion zone of positive electrode plate is made by the metal (nickel-foamed metal) of the nickel foaming that is coated with nickel hydroxide.The conversion zone of negative electrode plate is made by the punching press nickel metallic plate that is coated with the material (such as hydrogen adsorbing alloy) that constitutes negative electrode.Be actually surface reaction because produce the reaction of electric energy, thereby battery lead plate is extremely thin usually to reduce material cost and weight.Current-collector 11 is generally nickel-clad copper or the steel with thermal conductive resin and conductivity.Battery lead plate wherein is connected to the prismatic batteries of current-collector by electron beam welding or carbon dioxide laser welding, and current-collector is generally thin nickel-plated sheet, and this is because the actual place of being welded to connect is positioned at the surperficial back of entering of welding source.
In the formation of electrode plate groups 10, the part of leading of battery lead plate is at first wrapped up together.Wrapping under this linguistic context includes but not limited to that each part of leading of electrode plate groups pushes, packs, assembles, welds or tighten together.The part of leading of wrapping can be kept form by soft soldering, welding or such as the mechanical fasteners mode of riveted joint then.And before the part wrapping together of leading, the electrode group has been a cross structure usually, and wherein opposite polarity adjacent electrode plates is in the relation of close packing.
