New functional conducting poly-3,4-ethylenedioxythiopene:polystyrene sulfonate/carboxymethylcellulose binder for improvement of capacity of LiFePO4-based cathode materials

Alternative binders for sustainable electrochemical energy storage – the transition to aqueous electrode processing and bio-derived polymers

“…The most prominent (water-soluble) polymer in this regard is certainly PEDOT:PSS. This conductive polymer has been combined with CMC 141,142 and carboxymethyl chitosan. 136 In combination with CMC, Eliseeva et al 141 reported very remarkable specific capacities at lower and higher dis-/charge rates, i.e., 148 and 126 mA h g À1 at 0.2C and 5C, respectively, as well as excellent cycling stability with only 1% decay over 100 cycles at 1C.…”

Investigation on xanthan gum as novel water soluble binder for LiFePO 4 cathode in lithium-ion batteries

“…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.…”

Perspective potential of polymer-based biosensor chips in food industry and clinical diagnostics

“…The polyurethane layer that can be part of glucose biosensor is responsible for biosensor sensitivity and intensity of detection signal [11,12]. Poly(lactic acid) (PLA) [3,[15][16][17][18] Poly(lactic-co-glycolic acid) (PLGA) [4,5,18,24,[27][28][29][30][31] Poly(3,4-ethylenedioxythiopene) [24][25][26] Poly(3-aminobenzoic acid) [24,[27][28][29] Poly(pyrrole-3--carboxylic acid) [24,30,31] The polymers which are distinguished by their biocompatibility and biodegradability are especially applicable in medical purposes. Here we are talking about synthetic polymers, such as poly(lactic acid) (PLA) and its copolymer (e.g., poly(lactic-co-glycolic acid) (PLGA)), which are approved by Food and Drug Administration (FDA) and commonly used in drug targeting and biosensor production.…”

“…Poly(3,4-ethylenedioxythiopene) is a synthetic polymer which in combination with some other substrates can act as binder for improvement of cathode stability and its electrochemical properties [26]. Baba and Knoll reported the possibility of using the poly(3,4-ethylenedioxythiopene) in designing DNA biosensors, where this polymer was used for modification of platinum component of the biosensor [35].…”
