Abstract

Polyperinaphthlenic organic semiconductor (PPNOS) films with polyperinaphthalene (PPN) structure for anode electrodes for ultra thin rechargeable Li ion batteries are prepared on temperature-controlled substrates by excimer laser ablation (ELA) of 3, 4, 9, 10-perylenetetracarboxylic dianhydride (PTCDA) or mixture target of PTCDA with a few metal powder (PTCDA/M) using a 308 nm (XeCl) pulsed excimer laser beam. It is demonstrated that ELA of PTCDA at a fluence of less than 0.5 Jcm^-2pulse^-1 enables us to obtain PPNOS on a substrate at 300 degree(s)C. It is found that ELA of PTCDA/Co at a fluence of more than 1.0 Jcm^-4pulse^-1 leads to produce effectively fragments without anhydride groups of PTCDA. FT-IR and Raman spectroscopies reveal that ELA of PTCDA/Co enables us to obtain better-defined PPN films with electric conductivity of approximately 1x10^-1Scm^-1 on a substrate at 300 degree(s)C. Electrochemical doping characteristics of lithium ion into the films obtained by ELA are performed to verify the lithium doping mechanism by in situ Raman spectroscopy. Furthermore a trial piece of thin lithium ion rechargeable battery with the films is fabricated to appraise performance of the films as anode thin electrodes for ultra thin rechargeable lithium ion batteries.
