“…Among various aqueous polymeric binder demonstrated so far, polyacrylic acid (PAA) and its neutralized salts (PAALi, PAANa and PAAK) [5][6][7][8], chitosan and its derivatives (CTS, CCTS and CN-CCTS) [9][10][11], lithium or sodium salts of carboxymethyl cellulose (CMCLi, CMCNa) and its composite binder (CMC-PEDOT:PSS) [12,13], styrene-butadiene rubber (SBR) [7], poly vinyl acetate (PVAc) [14] and polytetrafluoroethylene (PTFE) [15] have been employed and studied for LFP cathode, which are superior to the conventional PVDF in battery performances such as either promoting the cycle stability or enhancing the rate capability. Besides the water-soluble binders mentioned above, some NMP-based binders such as polyaniline (PANI) [16], poly(methyl methacrylate) (PMMA) [17], poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) [18], and sodium alginate functionalized with 3,4-propylenedioxythiophene-2,5-discarboxylic acid (SA-PProDOT) [19] for LFP cathode were also investigated.…”

“…Also, Device 3 (w/o TX100) featured more endothermic heating during charging step. In order to explain these observations, four hypotheses were examined including (i) parasitic reversible redox reactions involving the CMC binder, [22][23][24] (ii) reversible ion solvation/desolvation, 25 (iii) differences in ion size and diffusion coefficient in the electrolytes, 16 and (iv) asymmetric charging mechanisms. 26 Note that the present calorimeter was configured for two electrode configuration and could not provide the potential evolution across each electrode separately.…”

This study aims to investigate the effect of electrode composition on heat generation in electric double layer capacitor (EDLC) electrodes under galvanostatic cycling. EDLCs consist of two identical electrodes usually made of a mixture of (i) carbon-based material, (ii) binder, and (iii) other conductive additives. These constituents were found to influence the capacitance and internal resistance of the device and the heat generation rate in the positive and negative electrodes. Indeed, the heat generation rate was measured using an isothermal calorimeter in both electrodes of five EDLC devices with different electrode compositions but the same electrolyte consisting of 1 M LiPF 6 in EC:DMC. The reversible heat generation rates at the positive and negative electrodes were nearly identical in absence of CMC. However, in devices containing CMC, the reversible heat generation rate in the positive electrode was significantly larger than that in the negative electrode. Such asymmetric heating was attributed to asymmetry in the charging mechanism due to the overscreening effect caused by interactions between the anionic functional groups of CMC and the cations at the negative electrode. Electric double layer capacitors (EDLCs) have received significant attention in recent years for electrical energy storage applications in particular those requiring rapid charging/discharging, such as regenerative braking in electric vehicles, 1 smart grids, 2 and renewable energy harvesting systems.3-5 Indeed, EDLCs can provide higher power density, higher cycle efficiency, and longer lifetime than batteries. 4,6 EDLC devices consist typically of two carbon-based electrodes partitioned by a separator immersed in aqueous or organic electrolytes. EDLCs store electrical energy in the electrical double layer of ions forming at electrode/electrolyte interface.Heat generation in EDLC is a major concern since these devices are usually cycled under high current density resulting in excessive temperature rise.7 This, in turn, can lead to (i) accelerated cell aging, [8][9][10] (ii) increased self-discharge rates, 9,11 and possibly (iii) electrolyte decomposition and evaporation. 9,12 Heat generation in EDLCs can be classified into irreversible and reversible heat generation rates. 7,[13][14][15][16][17] Irreversible heat generation has been attributed, both theoretically and experimentally, to Joule heating. 7,9,11,[13][14][15][16][17][18][19][20] It is constant throughout the EDLC cell and equal to the product of the EDLC internal resistance and the square of the imposed current. 7,[14][15][16] On the other hand, reversible heat generation rate in the entire device was theoretically and experimentally found to be exothermic during charging and endothermic during discharging.7,14-16 The time-averaged reversible heat generation over a charging step was shown to be proportional to the imposed current under galvanostatic cycling.7,14-16 Experimentally, reversible heat generation has been assumed to be identical in both the positive and negative e...

“…Thus, a large amount of effort has been put into the creation of an environment-friendly and cost-effective binder for lithiumion batteries. Extensive research has been conducted into in this field, such as carboxymethyl cellulose (CMC), mainly as its sodium neutralized derivative, and polyacrylic acid (PAAH) [8][9][10][11]. Recently, some new kinds of binders have been tested for lithium-ion batteries, for example acrylate polymers, such as polyacrylic acid (PAA) containing carboxyl groups maintain excellent cyclic retention for C-Si-based electrode materials thanks to hydrogen bonding.…”

This paper discusses the impact of the structure and properties of three different polymer binders: polyvinylidene fluoride, sodium carboxymethyl cellulose and polyvinyl alcohol, on the electrochemical properties of spherical graphite anodes for Li-ion batteries. Electrochemical tests indicate that the nature of polyvinylidene fluoride contributes in decreasing the cycle life of graphite electrodes in contrast to effective water-based binders. This study demonstrates the possibility of manufacturing graphite-based electrode for Li-ion batteries that cycle longer and use water in the processing, instead of hazardous organic solvents like N-methylpyrrolidone, thereby improving performance, reducing cost and protecting the environment.
