CHAPTER 3 LITHIUM-ION BATTERIES
2.1.1. Battery Structure. 2.1.1.1. Cell Reaction . 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 -
