▎ 摘　　要

Pseudocapacitance boosts the capacitance of supercapacitors by introducing additional redox sites with fast faradaic reactions. Here, we demonstrate the preparation of pseudocapacitive electrodes by inkjet printing bis-terpyridyl based molecular cobalt complexes as pseudocapacitive additives on laser induced graphene films. The substrate temperature during inkjet printing can effectively tune the morphology of the pseudocapacitive additives by overcoming the influence of coffee ring effect. Under optimum conditions, the capacitance of the pseudocapacitive electrodes was enhanced for 75 times over pristine graphene films. This approach can also be employed for the deposition of other functional materials via inkjet printing. (C) 2019 Elsevier Ltd. All rights reserved.
