“…The decrease of Warburg constants σ w , which determine the values of the Warburg diffusion resistance, is also observed in this row: 203 (PVDF), 72 (CMC), and 44 Ohm s −1/2 (PEDOT:PSS/CMC). A similar tendency is observed for other electrode materials, such as LFMP [65], LTO [64] and LMO [66].…”

“…The advantages of the combined PEDOT:PSS/CMC binder are additionally supported by charge transfer kinetic aspects, which are investigated in many of the papers cited in Table 3. In particular, systematic impedance measurements are performed in [64][65][66][67] for the three discussed binders, and the data on the interfacial resistances and diffusion coefficients of Li + ions are evaluated. The comparison of kinetic parameters obtained for all investigated electrodes (LFP, LTO, LMO, and LFMP) with different binders reveals two main factors which are responsible for significant improvement of electrochemical performance of PEDOT:PSS/CMC bound electrodes.…”

“…The comparison of kinetic parameters obtained for all investigated electrodes (LFP, LTO, LMO, and LFMP) with different binders reveals two main factors which are responsible for significant improvement of electrochemical performance of PEDOT:PSS/CMC bound electrodes. It is found that in the row of binders PVDF-CMC-PEDOT:PSS/CMC, a gradual decrease of interfacial charge transfer resistance and the increase of Li + apparent diffusion coefficient takes place [64][65][66][67].…”

“…For instance, Figure 2a,b shows the electrode layers of LTO PEDOT:PSS/CMC and LFMP PEDOT:PSS/CMC , which perfectly adhere to the current collector. The electrode layers with PEDOT:PSS/CMC binder successfully maintained integrity after long galvanostatic charge-discharge (GCD) tests [64,66,68,69].…”

The electrodes of lithium-ion batteries (LIBs) are multicomponent systems and their electrochemical properties are influenced by each component, therefore the composition of electrodes should be properly balanced. At the beginning of lithium-ion battery research, most attention was paid to the nature, size, and morphology peculiarities of inorganic active components as the main components which determine the functional properties of electrode materials. Over the past decade, considerable attention has been paid to development of new binders, as the binders have shown great effect on the electrochemical performance of electrodes in LIBs. The study of new conductive binders, in particular water-based binders with enhanced electronic and ionic conductivity, has become a trend in the development of new electrode materials, especially the conversion/alloying-type anodes. This mini-review provides a summary on the progress of current research of the effects of binders on the electrochemical properties of intercalation electrodes, with particular attention to the mechanisms of binder effects. The comparative analysis of effects of three different binders (PEDOT:PSS/CMC, CMC, and PVDF) for a number of oxide-based and phosphate-based positive and negative electrodes for lithium-ion batteries was performed based on literature and our own published research data. It reveals that the combined PEDOT:PSS/CMC binder can be considered as a versatile component of lithium-ion battery electrode materials (for both positive and negative electrodes), effective in the wide range of electrode potentials.

Transition metal oxide cathodes (TMOCs) such as LiNi0.8Mn0.1Co0.1O2 and LiMn1.5Ni0.5O4 have been widely employed in Li‐ion batteries (LIBs) owing to superior operating voltages, high reversible capacities and relatively low cost. Nevertheless, despite significant advancements in practical application, TMOC‐based LIBs face great challenges such as transition metal dissolution and volume expansion during cycling, which jeopardizes the future advance of high‐voltage TMOCs. As a critical component of cathode, polymeric binder acts as a crucial part in maintaining the mechanical and ion/electron conductive integrity between active particles, carbon additives, and the aluminum collector, hence minimizing cathode pulverization during battery cycling. Moreover, Polymeric binder with specialized functions is thought to offer a new solution to enhancing the electrochemical stability of the TMOCs. Therefore, this review aims at providing a comprehensive summary of the ideal requirements, design strategies and recent progress of polymeric binders for TMOCs. Future design perspectives and promising research technologies for advanced binders for high‐voltage TMOCs are introduced.
