A battery is a device that stores chemical energy and is available in an electric form. The batteries contain a series of electrochemical devices that contains one or more fuel cells, galvanic cells and flow cells. This electric battery is an interconnected array of one or more than one voltaic cells that are used in the cars, in torches, laptops, digital watches and almost every electronic goods that we use in our daily life.
Series of battery cells
The cells in the battery are connected either in parallel, in series or in both combinations. While the parallel combination of cells has the same voltage power as a single cell, it can supply a higher current than a single cell can. The parallel arrangements, however, suffer from a recurrent problem. If one cell discharges faster than its neighbor cell, then current will flow from the full cell to the empty cell, thereby wasting a lot of power and causing excess of overheating. Another marked disadvantage is if one of the cells gets short-circuited due to an internal fault, then its neighbor will be forced to discharge its maximum current into the faulty cell, thereby leading to sudden explosion.
