Electrical and electrochemical characterization of petrol cokes for lithium-ion cells

Several cokes and graphites have been electrically and electrochemically ch aracterized. The process of electrochemical lithium ion insertion into thes e materials has been analyzed for the purpose of assessing their performanc e as electrodes in advanced batteries and as potential candidates to substi tute for lithium metal. The results obtained prove the process of electroch emical lithium ion insertion into cokes and graphites to be strongly influe nced both by the ordered structure of the starting material and by the natu re of the anion of the lithium salt, which is used as electrolyte.
