The construction of a high-capacity intercalating cathode via an entirely new approach is reported—the self-assembly of nanometer-thick polyelectrolytes and graphite/graphite oxide nanoplatelets on a conducting substrate. The advantages of this approach as well as the charging and discharging behavior of a high-density (1232 mAhg–1 of graphitic carbon) rechargeable lithium-ion battery based on this cathode are described. This electrochemical cell holds commercial promise as it may be readily scaled up to an economically viable battery.
Cassagneau et al. (Sat,) studied this question.
