Polymeric materials for lithium-ion cells

Lithium-ion (Li-ion) cells have gained considerable attention in recent years as a power source for various applications owing to their high voltage, high energy density, low self-discharge, and excellent cycle life. Polymeric materials play a pivotal role in the processing, performance, and safety of Li-ion cells. The polymeric materials used in Li-ion cells include: binder for electrode processing, separator, electrolyte, and electrode active material. Active research is being pursued in all of these areas to improve the energy density, power density, cycle life, and safety of Li-ion cells. This review article gives an overview of the various polymeric materials used in Li-ion cells and the recent advances in these materials. Copyright © 2017 John Wiley & Sons, Ltd.
