摘要：
Negative electrodes of lithium-ion batteries containing a hard carbon with different levels of lithiation were characterized by Li-7 NMR experiments. A dramatic effect of washing the lithiated electrodes with the solvent was observed. The spectra of unwashed electrodes in different states of lithiation show that three species seem to be present: covalently bonded, intercalated and pseudo-metallic lithium species, respectively.
