The new electrochemical energy storage device, supercapattery, is introduced as a hybrid of supercapacitor and rechargeable battery. Selected research publications in 2018 on supercapattery and related topics are reviewed with critical analysis and comments. It is anticipated that supercapattery can and will play an important role in both mobile and stationary applications involving energy storage.
