PRISMATIC BUSSING METHOD AND DESIGN

摘要

An electrochemical cell including a prismatic electrode stack extending in a prismatic plane and having a plurality of positive electrode plates and a plurality of negative electrode plates stacked alternately with intervening separators therebetween. The positive electrode plates and the negative electrode plates are laterally offset so that end leads of the positive electrode plates extend from one side of the electrode stack and end leads of the negative electrode plates extend from an opposite side of the electrode stack. A positive bus strap is joined to the end leads of the positive electrode plates and a negative bus strap is joined to the end leads of the negative electrode plates such that said positive and negative bus straps and attaching portions of said end leads of the positive and negative electrode plates are disposed parallel to each other and perpendicular to the prismatic plane of the prismatic electrode stack. Further, a case may be provided for accommodating the prismatic electrode stack, the bus straps and liquid electrolyte.

1. An electrochemical cell, comprising:
a prismatic electrode stack extending in a prismatic plane and having a plurality of positive electrode plates and a plurality of negative electrode plates stacked alternately with intervening separators therebetween, the positive electrode plates and the negative electrode plates being laterally offset so that end leads of the positive electrode plates extend from one side of the electrode stack and end leads of the negative electrode plates extend from an opposite side of the electrode stack; a positive bus strap joined to the end leads of the positive electrode plates and a negative bus strap joined to the end leads of the negative electrode plates, wherein said positive and negative bus straps and connecting portions of said end leads of the positive and negative electrode plates are disposed parallel to each other and perpendicular to the prismatic plane of the prismatic electrode stack, whereby said end leads of the positive electrode plates are joined to said positive bus strap at said connecting portions and said end leads of the negative electrode plates are joined to the negative bus strap at said connecting portions; and a case accommodating the prismatic electrode stack, the bus straps and liquid electrolyte.
