We　report　on　the　impact　of　laser　processing　on　material　and　device　performance　characteristics　for　integrated　energy　applications.　A　femtosecond　laser　was　used　for　development　of　flexible　and　transparent　supercapacitors,　while　a　nanosecond　laser　was　successfully　exploited　for　high-performance　Al-air　battery　development.　A　laser　direct-write　process　enabled　integration　of　a　three-dimensional-structured　micro-supercapacitor　on　flexible　polymer　substrate,　exhibiting　peak　specific　capacitance　of　42.6　mF/cm(2)　at　current　density　of　0.1　mA/cm(2).　Femtosecond　laser　processing　was　also　exploited　for　development　of　a　novel　transparent　supercapacitor　on　silk　substrate.　The　MnO2　coated　transparent　supercapacitors　exhibited　high　transmittance　exceeding　59%.　Laser　processing　in　combination　with　printing　technique　was　used　for　development　of　a　novel　Al-air　battery.　The　nanosecond　laser　process　was　effective　in　sintering　the　anode　printed　using　Al　nanoparticle　ink.　The　efficiency　of　the　laser　sintering　process　was　reflected　in　good　battery　discharge　performance.
