Designing nanostructured carbons for the negative electrode of lithium batteries
Various parameters such as mesopore volume, microtexture, surface area, dangling bonds which can affect the value of irreversible capacity C-irr of a carbon anode have been considered. A new hypothesis is suggested and confirmed that active surface sites are at the origin of C-irr but not the specific surface area of carbon. An ideal proportional dependence has been found between C-irr and mesopore volume in the case of nanotubular materials. Surface modification of carbon fibres by a pyrolytic carbon coating has been successfully realized with an improvement of lithium insertion characteristics.
