The direction of flow of electricity in an electrolytic cell is the opposite from the flow when a battery is being used to power an external circuit, and the roles of the two poles or electrodes are reversed. Thus some writers will refer to the positive pole of a battery as its “cathode”.
The experimental results show that the proposed method in this paper can effectively detect surface multiple types defects of lithium battery pole piece, and the average recognition rate of defects reaches 98.3%, which is an effective and feasible automatic defect detection and identification method.
Another standard practice is the use of a red wire for positive and a black wire for a negative connection. Finding and using the proper polarity and the correct flow of current is crucial to the safe and effective use of electricity.

The longer, thin line represents the positive pole and the shorter, thick line represents the negative pole. Several cells connected together form a battery of cells. Thus in principle a single cell should strictly be called just that – a cell – and the word battery should be restricted to a battery of several cells. However, in practice ...

solder causes lithium to melt. The separator melts and becomes perforated. The positive and negative poles are welded together, causing "internal shorting." In terms of the battery characteristics, the open-circuit voltage and electrical capacity are both reduced. The battery loses its functions or it bursts in rare cases.
