Other Materials for Lithium-Ion Batteries

Yuping Wu, Shiyong Zhao, and Teunis van Ree

Negative and positive electrode materials, electrolytes, and separators are four key components for lithium-ion batteries. However, other auxiliary materials such as electronic conductive agents, binders, solvents for slurry preparation, positive thermal coefficient (PTC) materials, current collectors, and cases are also important in the production of complete lithium-ion batteries.

13.1 Electronic Conductive Agents

As shown in Figure 13.1, an electrochemical process for a battery needs a concurrent gain or loss of electrons and ions for the charge or discharge process to continue. However, electronic conductivities for electrode active materials ...
