Extended Data Fig. 7: BET data.
From: Trapped O2 and the origin of voltage fade in layered Li-rich cathodes

(a) BET data showing the pore size distributions for the pristine, 2nd cycle and 100th cycle samples. To remove the contribution from carbon and binder which were present in all samples, the pristine data were subtracted from the 2nd and 100th cycle data to better observe the changes in cathode particle porosity, (b).
