My PhD is in Materials science in the field of environmental remediation (water decontamination) using different advanced materials as adsorbents. I also have expertise in computational chemistry and currently, I am doing some DFT calculations on electrocatalytic water splitting using some transition metal selenide hybrid materials. And this work has been published in a good ACS journal. 

I am interested in seeking a postdoc and expanding my horizon in the field of energy production (water splitting, lithium ion batteries, hydrogen production and storage, etc.) using materials as catalysts (both experimentally and computationally).  

How should I back my research profile while seeking a position in this field with no prior experience? The postdoc openings demands a desirable candidate with extensive record and experience in batteries and handling elecrodes, etc. which I clearly do not have.
