Application of Guar Gum and its Derivatives as Green Binder/Separator for Advanced Lithium‐Ion Batteries

Abstract

Since their first commercialization in the 1990s,lithium-ion batteries (LIBs) have become an indispensible part of our everyday life in particular for portable electronic devices. LIBs have been considered as the most promising sustainable high energy density storage device. In recent years, there is a strong demand of LIBs for hybrid electric and electric vehicles to lower carbon footprint and mitigate climate change. However, LIBs have several issues, for example, high cost and safety issues such as over discharge, intolerance to overcharge, high temper-ature operation etc. To address these issues several new types of electrodes are being studied. Traditional binder PVDF is costly, difficult to recyle, undergoes side reactions at high temperature and cannot stabilize high energy density electrodes. To overcome these challenges, diiferent binders have been introduced with these electrodes. This minireview is focused on the application of guar gum as a binder for different electrodes and separator. The electrochemical performance of electrodes with guar gum has been compared with other binders.

Heat-Resistant Lithium-Ion-Battery Separator Using Synchronous Thermal Stabilization/Imidization

“…With the expansion of portable electronics and long-range electric automobiles and the use of clean energy sources such as solar, wind, and hydropower, electrochemical energy storage technology plays a vital role in society. , Among various energy storage systems, lithium-ion batteries (LIBs) have garnered significant attention due to their high operating voltage and excellent cycle performances. , It is worth noting that the thermal safety problems of LIBs affect their practical applications. For example, the thermal runaway of the separator will lead to electrode short-circuiting, resulting in substantial heat generation or even explosion, which is one of the main causes of battery accidents …”

Exploring the potential of poly (caprolactone) and guar gum biodegradable blend film: an investigation for supercapacitor

“…They exhibit chemical stability, making them resistant to corrosion or degradation, a crucial factor for supercapacitors needing to endure harsh environments. Furthermore, BPEs can be crafted from environmentally friendly materials such as polymers and organic solvents [1][2][3]. A blend of poly (vinyl alcohol)poly (styrene sulphonic acid) demonstrated a specific capacitance of 40 F g −1 , primarily due to Grotthus-type proton movement, where a proton rushes from H 3 O + to a hydrogen-bonded water molecule [4].…”

Engineering Dry Electrode Manufacturing for Sustainable Lithium-Ion Batteries

“…These progressive LIBs are characterized by high energy densities and larger dimensions, making safety precautions an essential prerequisite [42][43][44][45][46]. The utilization of the dry process is essential in the continuous efforts to develop next-generation advanced LIBs characterized by elevated energy density, extended cycling lifetimes, and exceptional safety standards.…”
