Carbon Nanocluster-Mediated Nanoblending Assembly for Binder-Free Energy Storage Electrodes with High Capacities and Enhanced Charge Transfer Kinetics.

In particular, the b ‐value in the cathodic sweep of 0.75−0.01 V (region III in Figure 2c ) showed a trend closer to 1.0, unlike other regions closer to 0.5 (including the conversion reaction in the cathodic sweep of 1.25−0.75 V (region II) and the Li ion insertion in the cathodic sweep of 2.00−1.25 V (region I) in Figure 2c ), suggesting that the charge storage in the low potential range partially resulted from the surface‐controlled process caused by the electrolyte‐derived surface layer at the interfaces among Fe 3 O 4 nanograins.
