Figure Lengend Snippet: a Schematics of the preparation and mass composition of electrode slurries using initially dilute 1.5% wt. CMC (standard slurry) or initially concentrated 3% wt. CMC (modified slurry). In both protocols, each 2000 rpm mixing step was preceded by 1 min premixing at 500 rpm; mixing was done in a Thinky planetary centrifugal mixer. b Colour-enhanced top-surface BEI of brominated electrodes prepared from standard and modified slurries. The inset shows an SEM image of a CBD cluster. c Logarithmic histograms of CBD cluster size distribution in standard and modified electrodes, based on analysis of 10 BEI images of each electrode. d Violin plots showing the distribution of electronic resistivity of standard and modified electrode coatings before and after calendering, determined by four-point probe measurements. Five (uncalendared) and eight (calendared) samples of each coating were measured ten times each. Sample properties are summarised in Supplementary Table . BEI image segmentation and CBD clustering analysis were done as described in “Methods”. Source data are provided as a Source Data file.
