The polyacrylic latex (LA132) was firstly reported as a water-soluble binder for LiNi 1/3 Co 1/3 Mn 1/3 O 2 (NCM) cathode in Li-ion battery. The electrochemical performances of NCM cathode with LA132 binder were investigated and compared with the conventional water-soluble sodium carboxymethyl cellulose (CMC) and commercial nonaqueous polyvinylidene difluoride (PVDF). NCM cathode with LA132 binder exhibited a much higher specific capacity of 146 mAh g −1 and capacity retention of 96.4 % after 100 cycles as compared with 122 mAh g −1 /88 % and 121 mAh g −1 / 75% for the NCM electrode with CMC and PVDF, respectively. In addition, NCM cathode with LA132 binder exhibited better rate capability than that of CMC and PVDF, e.g., retaining 34.3 % capacity of C/5 at 5 C rate as compared with 28.5 and 10.9 % for CMC and PVDF, respectively.

“…Recently, it has been reported that NCM electrode with CMC binder exhibited better electrochemical properties than that of PVDF and alginate [4,5,26,27]. However, the electrode slurry using CMC binder has difficult to be dispersed homogenously onto an Al foil during fabricating of the electrode sheet.…”

Increasing the environmental benignity of lithium-ion batteries is one of the greatest challenges for their large-scale deployment. Toward this end, we present herein a strategy to enable the aqueous processing of high-voltage LiNi Mn O (LNMO) cathodes, which are considered highly, if not the most, promising for the realization of cobalt-free next-generation lithium-ion cathodes. Combining the addition of phosphoric acid with the cross-linking of sodium carboxymethyl cellulose by means of citric acid, aqueously processed electrodes with excellent performance are produced. The combined approach offers synergistic benefits, resulting in stable cycling performance and excellent coulombic efficiency (98.96 %) in lithium-metal cells. Remarkably, this approach can be easily incorporated into standard electrode preparation processes with no additional processing step.

“…[10][11][12] Thus, the switching from a using PVdF/NMP to aqueous-based systems are considered because they facilitate handling and good dispersion of electrode components. [13][14][15][16][17] Carboxymethyl cellulose (CMC) has been widely used as a promising aqueous-based binder for both negative and positive composite electrodes. In particular, recent reports reveals that the CMC binder is appropriate for fabricating positive composite electrodes composed of LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) [18,19], LiNi 0.4 Mn 1.6 O 4 (LNM) [20], LiFePO 4 (LFP).…”

Alginic Acid as a New Aqueous Slurry-Based Binder for Cathode Materials of LIB

2015

Alginic acid (Alg-H) was applied as a novel aqueous binder for LiNi1/3Co1/3Mn1/3O2 (NMC) positive electrode for lithium-ion batteries (LIBs). We successfully obtained the pH-controlled aqueous slurry without any corrosion of NMC, which can also prevent a corrosion of an aluminum current collector. Using Alg-H can realize higher adhesive strength of the electrode even low content of 2 wt.% than using carboxymethyl cellulose and polyvinylidene difluoride. Galvanostatic charge-discharge cycle performances of both half cell and full cell composed of the NMC electrode with Alg-H are stable even at high voltage operation of 3.0-4.5 V, indicating that no side reaction including corrosion of the aluminum current collector and the decomposition of Alg-H binder occurs in this system. Moreover, this cell maintained over 90% of the initial discharge capacitance even after 100 cycles. These results suggest that the Alg-H binder has high potential to be used as an aqueous binder for positive electrodes of LIBs.
