AbstractRenewable energy sources and electric automotive transportation are popular topics in our belated energy‐conscious society, placing electrochemical energy management as one of the major technological developments for this new century. Besides efficiency, any new storage technologies will have to provide advantages in terms of cost and environmental footprint and thus rely on sustainable materials that can be processed at low temperature. To meet such challenges future devices will require inspiration from living organisms and rely on either bio‐inspired or biomimetic approaches.
