Heat Effects during the Operation of Lead-Acid Batteries
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This …

CHAPTER 3 LITHIUM-ION BATTERIES
A Li-ion battery is composed of the active materials (negative electrode/positive electrode), the electrolyte, and the separator, which acts as a barrier between the negative electrode and positive electrode to avoid short circuits. The active materials in Liion cells are the components that - participate in the oxidation and reduction reactions.
