What is styrene-butadiene rubber (SBR)?

Spherical styrene-butadiene rubber (SBR, TRD2001, JSR Corporation, Tokyo, Japan) with a density of 1.0 g/cm 3, a diameter d SBR = 180 nm and 48 wt% solid mass fraction was used as a binder. According to the manufacturer, the SBR binder particles were obtained from emulsion polymerization.

Which slurries are used to prepare battery electrodes?

Battery electrodes were prepared with (a) battery slurry containing 1.41 vol% SBR binder and (b) capillary suspension containing 1.41 vol% SBR binder and 2 vol% octanol. These SEM images indicate a different failure and delamination characteristic for the electrodes made from the regular and capillary-suspension-type battery slurries.

What is sbrx electrode?

It should be noted that a simplified notation, SBRx binder, is adopted hereinafter for the mixed binder of SBRx and CMC, as all of the SBRx latexes were used by combining with CMC as binders in this study. Therefore, SBRx electrode means an LCO composite electrode with the mixed binder of SBRx and CMC.

What is SBR CN?

SBR CN, which is modified by acrylonitrile, shows a high solvent uptake and remarkable electrode performance in terms of rate capability and self-discharge suppression. 1. Introduction Lithium-ion secondary cells comprise four components: positive and negative electrodes, a separator, and an electrolytic solution.

Do additional SBR-particles affect the flow behavior of capillary-suspension-type battery slurries?

Here, we investigated how additional SBR-particles, widely used as a binder in commercial battery slurries, affect the flow behavior and microstructure of capillary-suspension-type battery slurries that included graphite, an aqueous CMC solution, and 1-octanol as a secondary fluid.

Why does a SBR CN electrode have a suppressed self-discharge?

The SBR CN electrode shows an Rf value as large as 50 Ω after 50 cycles, suggesting that the suppressed self-discharge shown in Fig. 4 is probably due to the thicker surface layer preventing self-lithiation.
