Interest in printed batteries is growing due to their applications in our daily lives, e.g., for portable and wearable electronics, biomedicals, and internet of things (IoT). The main advantages offered by printing technologies are flexibility, customizability, easy production, large area, and high scalability. Among the printing techniques, gravure is the most appealing for the industrial manufacture of functional layers thanks to its characteristics of high quality and high speed. To date, despite its advantages, such technology has been little investigated, especially in the field of energy since it is difficult to obtain functionality and adequate mass loading using diluted inks. In this review, the recent results for printed lithium-ion batteries are reported and discussed. A methodology for controlling the ink formulation and process based on the capillary number was proposed to obtain high printing quality and layer functionality. Specific concerns were found to play a fundamental role for each specific material and its performance when used as a film. Considering all such issues, gravure can provide high performance layers. A multilayer approach enables the desired layer mass loading to be achieved with advantages in terms of bulk homogeneity. Such results can boost the future industrial employment of gravure printing in the field of printed batteries

From the State as Supplier to the State as Promoter and Contractual Party: Towards a New Economic Policy. Over recent years, political and economic strategies in Italy have been characterized by new ways for intervention: not only the State as a supplier of public resources, often in a deficit situation, but also the State as a marketing initiatives promoter, inside the market, using private resources; the State as active part of agreements and contracts with private entities. In consideration of the high level of public debt and low growth perspectives, the Italian way identifies measures at the border between public and private law. Main examples deal with the subscription, by the Italian Treasury Ministry, of hybrid capitalization instruments (the so called Tremonti bonds); the debt moratorium agreement for small and medium enterprises towards credit system; the closed-end public-private fund in order to support the capitalization of small and medium enterprises; the «Fondo Strategico Italiano»; the «Banca del Mezzogiorno»; contractual devices for granting liquid assets to companies that supply Public Administration. The paper aims to give evidence of such fil rouge in the recent economic politics and proposes necessary changes in order to convert the new approach from temporary into structural, with reference both to the role of the public official in the context of the State who acts as promoter/ contractor and the juridical instruments that allow these ways of intervention. In this connection, there is a large use of private autonomy, in the form of contractual autonomy, for implementing public interests. Public orders are replaced by contracts in order to pursue targets of public relevance in the economic policy. Emblematic example is the experience of the Italian Competition Authority (Autorità Garante della Concorrenza e del Mercato) and, in general, of the national and European competition authorities, with particular reference to the commitments often undertaken by the parts of a concentration, or by entities under investigation for suspected infringement of antitrust rules, to correct the anti-competitive conduct
