Linked to capacity fade is the internal resistance (IR) rise curve which quantifies the amount of opposition to the flow of current in and out of a battery [6]. A considerable volume of work has been done to understand [5], [7], detect [6], [8] and predict [6], [8], [9], [10] key quantities relating to the evolution of cell capacity and IR.
Batteries, current, and Ohm''s law
If the wire is connected to a 1.5-volt battery, how much current flows through the wire? The current can be found from Ohm''s Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated. The first step, then, is to find the resistance of the wire: L is the length, 1.60 m.
