“…After crosslinking, the hydrogenated nitrile butadiene rubber (HNBR) is electrochemically stable and outperforms PVDF in terms of mechanical strength, adhesion, and cell performance. [ 42 ] After crosslinking, the glass transition temperature ( T g ) of HNBR is as low as −28 °C, which makes it stay at a rubbery state, allowing a high flexibility of the polymer chains. The tensile test indicates that crosslinked HNBR can be stretched to 400% under 2 MPa tensile stress; comparably, the PVDF can only be reversibly deformed at an elongation of 10%.…”

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.

High areal density and high energy Li‐ion electrodes were prepared using a high throughput green, solventless and inexpensive melt process leading to electrodes of controlled porosity. Melt formulations were developed for NCA cathodes and graphite anodes. The formulations were based on commercially available and inexpensive elastomeric or thermoplastic binders, conventional conducting fillers and >90 wt% electrode active materials. A large range of loadings could be achieved, from 4 to 40 mg cm−2 single side. Electrochemical performances in half cells (coin cells) are reported. High capacity and cyclability for high loadings of NCA cathodes and graphite anodes were demonstrated. Areal capacities over 5 mAh.cm−2 in coin cells were obtained at a C/5 rate. Cycling at high rates, up to 5 C was demonstrated.

“…Its most notorious downside is the presence of fluorine in its structure, which can hamper recyclability. To the best of our knowledge, nonrecyclable materials are most often either buried or pyrolyzed, which could release harmful fluorocarbons in the environment. − Other binder options include polyethylene- co -ethyl acrylate- co -maleic anhydride (TPE) and hydrogenated nitrile butadiene rubber (HNBR), two polymers which we previously investigated. ,, DoE are remarkable, as they can be used to study more than one polymer at a time, with a reduced number of experiments and no sacrifice to the model’s precision.…”

Today, energy conversion devices typically rely on composite electrodes made of several materials interacting with one another. Understanding their individual and combined impacts on performance is essential in the pursuit of optimized systems. Unfortunately, this investigation is often disregarded in favor of quick publishable results. Here, designs of experiments are shown as capable of meeting both ends. Less than 100 different electrode formulations are defined with two active materials (LiFePO 4 and Li 4 Ti 5 O 12 ), two carbonaceous additives (carbon black and carbon nanofibers), and three binders (polyvinylidene fluoride, polyethylene-co-ethyl acrylate-co-maleic anhydride (Lotader 5500), and a hydrogenated nitrile butadiene rubber). Correlations with strong descriptive statistics are found between formulation and different limitations, indicating that maximum active material content should always be favored with a small fraction of both conductive additives and minimal binder content. With the help of designs of experiments, Lotader 5500-bound electrodes are optimized beyond typical formulations found in the literature.
