“…Thus, this study proves that replacement of NMP with water in NMC 532 can be done without forfeiting its electrochemical performance and also that small modifications can cause a huge impact on the aging behavior of a full cell. 124 Zhu and co-workers studied the electrochemical performance of NMC 622 cathode using Na-CMC and TRD 202A binders. Acetic acid was added to the slurry during mixing in order to adjust the pH between 7.4 and 12.1.…”

The current technologically advancing society requires the development of economically profitable and efficient electrode fabrication routes for lithium ion cells. Binders play an important role in deciding the performance parameters, viz., energy density, rate capability, and cycle life of lithium ion cells. The present review provides a practical guide for the development of aqueous binder based cathodes for lithium ion (Li-ion) cells. In this review, we first discuss the need for aqueous binders in the production of electrodes, particularly for cathodes in Li-ion cells, summarize the challenges in the fabrication of aqueous binder based cathodes, and then highlight the recent developments in aqueous binder based cathodes, targeting to provide a stepping stone for the development of aqueous binder based cathodes with improved sustainability and enhanced electrochemical performance. Aqueous binders for different generations of cathode materials are reviewed in detail with special emphasis given to commercially employed cathode materials.

“…45,46 One way to prevent Al foil corrosion is also to use a carbon coated or corona treated Al foil. 11,22,26,[47][48][49] Using such surface modified Al-foils, the electrode paste preparation is simplified, but these foils are very costly which is disadvantageous for the use in battery mass-production.…”

The combination of two different binders: styrene-butadiene rubber (SBR) and polyacrylic acid (PAA), in combination with carboxymethylcellulose (CMC) has been investigated for aqueous electrode preparation of LiNi0.83Co0.12Mn0.05O2 positive electrodes. The use of Ni-rich active materials in Li-ion batteries is becoming industry standard, however, such Ni-rich cathode materials are sensitive to water, which makes the aqueous electrode manufacturing especially challenging and based on industry-information even impossible. The preparation of aqueous Ni-rich electrodes with areal capacities of 2.7 mAh cm−2 and densities of up to 3.5 g cm−3 was investigated and optimized. The electrochemical evaluation in bi-layer pouch cells showed that the performance depends heavily on the individual combination of binders. Using PAA binders, the best electrode reached 80% capacity retention only after 470 cycles. In contrast, the best electrode with SBR binder performed very similar to the PVdF reference electrode in view of rate capability and a specific 1 C capacity with 177 mAh gCAM −1 compared to 179 mAh gCAM −1 of the PVdF reference electrode. In addition, this SBR-based electrode showed excellent cycling stability at 1 C/1 C with capacity retention of 84% after 1,000 cycles; therefore, matching typical requirements for such electrodes in electric vehicle batteries.

“…While binder combinations from carboxymethylcellulose (CMC), styrene butadiene rubber (SBR), and poly(acrylic acid) (PAA) are widely used for the processing of negative electrodes (anodes), various binders and combinations have been and are currently explored for the use with various cathode chemistries. [23] Examples include, but are not limited to, works with Na-CMC for LiFePO 4 , high voltage composite cathodes or various NCM stoichiometries, [24][25][26][27][28] additives or protective coatings for the Alfoil, [29][30][31] and investigations of the positive effect the natural pH of NCM532 in water [32] and PAA. [33] In addition, for example, an advanced lithium CMC and PAA co-polymer composite binder indicated promising opportunities for tailoring binder properties for industrial applications.…”

Investigation of Lithium Polyacrylate Binders for Aqueous Processing of Ni‐Rich Lithium Layered Oxide Cathodes for Lithium‐Ion Batteries

et al. 2022

Ni-rich layered oxide cathodes are promising candidates to satisfy the increasing energy demand of lithium-ion batteries for automotive applications. Aqueous processing of such materials, although desirable to reduce costs and improve sustainability, remains challenging due to the Li + /H + exchange upon contact with water, resulting in a pH increase and corrosion of the aluminum current collector. Herein, an example was given for tuning the properties of aqueous LiNi 0.83 Co 0.12 Mn 0.05 O 2 electrode pastes using a lithium polyacrylate-based binder to find the "sweet spot" for processing parameters and electrochemical performance. Polyacrylic acid was partially neutralized to balance high initial capacity, good cycling stability, and the prevention of aluminum corrosion. Optimized LiOH/polyacrylic acid ratios in water were identified, showing comparable cycling performance to electrodes processed with polyvinylidene difluoride requiring toxic N-methyl-2pyrrolidone as solvent. This work gives an exemplary study for tuning aqueous electrode pastes properties aiming towards a more environmentally friendly processing of Ni-rich cathodes.
