I remember the physics lessons at school when we studied electrical systems. We learned Ohm’s law, which told us that electric current flows from a positive to a negative electric potential while the electrons move in the opposite direction. Kirchhoff’s lawtaught us that there must be continuity in current; i.e..

Customer ServiceThe principle behind a battery''s functioning lies in a chemical reaction that takes place inside it. Batteries consist of two electrodes – a positive electrode called the cathode and a negative electrode called the anode – immersed in an electrolyte solution. The mechanism of a battery involves the movement of ions and electrons within this solution.
Customer ServiceAs we look at the battery from this view, we see that current flows through the battery cells from the positive to the negative, and that''s using conventional current theory. What actually happens is the electrons flow in the opposite direction from the negative to the positive. But we''ll cover that a little later in the article.
Customer ServiceDuring the discharge of a battery, the current in the circuit flows from the positive to the negative electrode.

The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the anode to the cathode and vice versa through the separator.
For ease in analyzing circuits, we suggest drawing a “battery arrow” above batteries that goes from the negative to the positive terminal. The circuit in Figure 20.1.4 20.1. 4 is simple to analyze. In this case, whichever charges exit one terminal of the battery, must pass through the resistor and then enter the other terminal of the battery.
