From: Numerical Study of Composite Electrode's Particle Size Effect on the Electrochemical and Heat Generation of a Li-Ion Battery J. Nanotechnol. Eng. Med. 2016;6(4):041003-041003-8. doi:10.1115/1.4032012 Figure Legend: Maximum capacity of the battery during charging (a) and discharging (b) at different C-rates for the sizes in Table 3. Maximum capacity decreases with the increase of solid particle's sizes. As the size increases, although the surface area of the solid particles increases, the active surface area for electrochemical decreases, hence, the maximum capacity decreases with increasing the sizes.
