Paper Abstract

Carbonous nano-particles basically consisting of PPN, one of the low dimensional conducting polymers, are prepared on substrates at various temperatures by excimer laser ablation of 3, 4, 9, 10-perylenetetracarboxylic dianydride using a 308nm pulsed excimer laser beam. Particles deposited on the substrates are applied to anode electrodes for ultra thin rechargeable Li ion batteries. Substrate temperature dependence of effective capacitance of lithium ions at first cycle are investigated. In addition, in-situ Raman spectroscopy of the particles under lithium ion doping and undoping is performed to elucidate the storage mechanisms of lithium ion at cis-polyacetylene-type edge of PPN structure. Reversible change of the spectrum in the region related C-H bending of PPN structure in lithium doping and undoping process supports a lithium insertion mechanism proposed by Zheng et al where lithium atoms bind on the hydrogene- terminated edged of hexagonal carbon fragments.
