While the same oxidation and reduction features are observed in LC-PB, the electrochemical behavior is somewhat different (Figure ). The redox processes show a significantly greater peak separation of 460 mV (transition of BG to PB) vs 150mV seen for HC-PB versa), illustrating a quasi-reversible process with much slower kinetics than HC-PB. This could be due to slower charge transfer or alternatively greater particle and contact resistance seen with LC-PB. Unwin and co-workers clearly illustrated that increased electrical resistance increased CV peak separation in scanning electrochemical cell microscopy measurements of LiMn 2 O 4 at fast scan rates of 1 V s -1 . Although the impact of resistance on peak separation is anticipated to be reduced by the slow scan rate of 0.77 mV s -1 used in our study, the impact of the relatively poor conductivity of PB (ca 1x 10 -7 S cm -1 ) should not be discounted. In particular the large aggregates of LC-PB seen by SEM (Figure ) with relatively poor dispersion, when compared to HC-PB, in the conductive carbon of the assembled matrix could well account for substantial resistance within the LC-PB cathode.
