The Impact of Polymer Electrolyte Properties on Lithium-Ion Batteries

Abstract

In recent decades, the enhancement of the properties of electrolytes and electrodes resulted in the development of efficient electrochemical energy storage devices. We herein reported the impact of the different polymer electrolytes in terms of physicochemical, thermal, electrical, and mechanical properties of lithium-ion batteries (LIBs). Since LIBs use many groups of electrolytes, such as liquid electrolytes, quasi-solid electrolytes, and solid electrolytes, the efficiency of the full device relies on the type of electrolyte used. A good electrolyte is the one that, when used in Li-ion batteries, exhibits high Li+ diffusion between electrodes, the lowest resistance during cycling at the interfaces, a high capacity of retention, a very good cycle-life, high thermal stability, high specific capacitance, and high energy density. The impact of various polymer electrolytes and their components has been reported in this work, which helps to understand their effect on battery performance. Although, single-electrolyte material cannot be sufficient to fulfill the requirements of a good LIB. This review is aimed to lead toward an appropriate choice of polymer electrolyte for LIBs.

“…As a result, replacing graphite anodes with materials having better capacity, energy, and power density is essential. 54 In 2019, Goodenough (University of Texas at Austin), Whittingham (Binghamton University in New York), and Yoshino (Asahi Kasei Corp and Meijo University in Japan) were given the Nobel Prize in Chemistry for their work on LIBs. The technology was made with a Cobalt oxide cathode and a petroleum coke anode.…”

Development of the ReaxFF Reactive Force Field for Li/Mn/O Battery Technology with Application to Design a Self-Healing Cathode Electrolyte Interphase

“…PYR 13 + cations are recognized for their efficacy in augmenting the stability of electrode−electrolyte interfaces within lithium-ion batteries. 60 This modification was implemented to assess the influence of PYR 13 + cations on the interplay between the electrolyte and the electrode−electrolyte interface within the Li x Mn y O z structure. Subsequently, FSI − anions were introduced into the system along with the other electrolyte molecules.…”

Designing polymer electrolytes for advanced solid lithium-ion batteries: recent advances and future perspectives

“…The widely accepted mechanism is the hopping transfer of Li ions from one site to another in one polymer chain or between polymer segments. 51 After Li salts are dissolved in a polymer matrix, the dissociated Li ions can coordinate with the polar groups in the polymer, such as -O-, -S-, -CRN, etc. Li ions jump between the coordinated sites under the driving force of the external electrical field.…”
