Abstract
A battery system includes a plurality of battery cells connected in parallel. Each battery cell includes a pair of positive and negative tabs extending from each of two opposing sides. The battery system also includes one or more pairs of adjacent joining pads, each pair connecting the positive and negative tabs of adjacent battery cells. The battery system also includes a terrace portion. The positive tab and the negative tab corresponding to one side of a battery cell at one end of the parallel connection extend out onto the terrace portion. A pair of bus-bars placed in the terrace portion allow the extension of the tabs. Each joining pad is made of a flexible material so as to allow the positive and negative tabs of adjacent battery cells to bend around the respective joining pad. The battery system can be configured in various shapes, such as curved.
