Abstract:
1. A battery cell comprising: a positive and negative plate cooperatively wound in a spiral assembly and a separator providing separation therebetween, each plate having a first side thereof and a second side thereof; first positive and negative busbars connected up with the first sides of the positive and negative plates, respectively, and second positive and negative busbars connected up with the second sides of the positive and negative plates, respectively; a sealed case therefor which extends between spaced first and second ends; and, first positive and negative terminals being arranged to protrude from the first end of the case and connected to the first positive and negative busbars, respectively, and second positive and negative terminals being arranged to protrude from the second end of the case and connected to the second positive and negative busbars, respectively, whereby said terminals are distributed to better service the thermal extraction of the current-resistive heating effects induced by the plates and/or busbars and eliminate relative hot-spots from developing in any under-served regions.
