“…From this point of view, some strategies can be directly transferred from those designed for graphite. For instance, water-soluble binders such as CMC, [32][33][34] PAA, [35,36] Na-alginate, [37,38] have also shown effectiveness in improving the electrochemical performance of LTO. An enhanced binding strength/adhesion, compared to the PVDF binder, can be achieved with those binders.…”

Polymer binders as a critical component in rechargeable batteries provide the electrodes with interconnected structures and mechanical strength to maintain the electronic/ionic transfer during battery cycling. The conventional binders, such as polyvinylidene fluoride (PVDF), are not ideal candidates due to their relatively low adhesiveness, weak mechanical strength, and poor functionality for high‐energy‐density batteries with a thick electrode and/or a high‐capacity electrode. Nevertheless, the binder has not yet received the attention that reflects its importance in batteries. The requirements of high energy density batteries make essential the exploration of advanced polymeric binders, which possess particular functions. In this review, state‐of‐the‐art binder design strategies are sorted in terms of the challenges of various electrodes (anodes and cathodes for lithium ion batteries (LIBs) and sulfur cathodes for Li–S batteries), which have been commercialized or have the potential for practical cells. A deep insight into how the polymeric binders improve the cell performance and the design principle of new binders is also provided. Finally, a perspective on the direction of future binder development for high‐energy‐density batteries with long cycle life is presented.

“…In a later work, Arbizzani and co‐workers studied not only the influence of the binder but also the electrolyte on the properties of the LTO electrode. [ 371 ] The combination of sodium alginate (SA) LTO electrodes operating in a glyme‐based electrolyte was evaluated in a half‐cell configuration and showed outstanding cycling performance over 600 cycles at 1C.…”

Materials in nature have evolved to the most efficient forms and have adapted to various environmental conditions over tens of thousands of years. Because of their versatile functionalities and environmental friendliness, numerous attempts have been made to use bio‐inspired materials for industrial applications, establishing the importance of biomimetics. Biomimetics have become pivotal to the search for technological breakthroughs in the area of rechargeable secondary batteries. Here, the characteristics of bio‐inspired materials that are useful for secondary batteries as well as their benefits for application as the main components of batteries (e.g., electrodes, separators, and binders) are discussed. The use of bio‐inspired materials for the synthesis of nanomaterials with complex structures, low‐cost electrode materials prepared from biomass, and biomolecular organic electrodes for lithium‐ion batteries are also introduced. In addition, nature‐derived separators and binders are discussed, including their effects on enhancing battery performance and safety. Recent developments toward next‐generation secondary batteries including sodium‐ion batteries, zinc‐ion batteries, and flexible batteries are also mentioned to understand the feasibility of using bio‐inspired materials in these new battery systems. Finally, current research trends are covered and future directions are proposed to provide important insights into scientific and practical issues in the development of biomimetics technologies for secondary batteries.

“…However, for moving toward more sustainable batteries, it is necessary to change from the beginning, starting from materials and processes. Several studies have been carried out on aqueous processes using water-processable binders [8][9][10][11]. Many of these binders come from natural sources or wastes, thus eliminating the need of using fluorinated binders that usually require toxic organic solvents, unless water-soluble fluorinated binders are used [12,13].…”

The increased percentage of renewable power sources involved in energy production highlights the importance of developing systems for stationary energy storage that satisfy the requirements of safety and low costs. Na ion batteries can be suitable candidates, specifically if their components are economic and safe. This study focuses on the development of aqueous processes and binders to prepare electrodes for sodium ion cells operating in aqueous solutions. We demonstrated the feasibility of a chitosan-based binder to produce freestanding electrodes for Na ion cells, without the use of organic solvents and current collectors in electrode processing. To our knowledge, it is the first time that water-processed, freestanding electrodes are used in aqueous Na ion cells, which could also be extended to other types of aqueous batteries. This is a real breakthrough in terms of sustainability, taking into account low risks for health and environment and low costs.
