That is, in this study, 1 C translates to a current density of 497 mA g –1 or 0.26 mA cm –2. Based on the theoretical …
First identify the positive and negative ends of the battery. On a typical Alkaline LR44 battery, the flat side (possibly with markings) will usually be the positive side. On the opposite side, a small circular protrusion should be visible. The side is typically the negative end. Now that you have determined the positive and negative ends of the battery, you can …
