3D POROUS Cu–Zn ALLOYS AS ALTERNATIVE ANODE MATERIALS FOR LI-ION BATTERIES WITH SUPERIOR LOW T PERFORMANCE
A joint team between ICMATE CNR Padova and Helmholtz Institute Ulm for Electrochemical Energy Storage has developed a novel class of lithium-ion battery (LIB) anodes based on Zn-rich porous CuxZn1-x intermetallic compounds. The carbon- and binder-free electrodes produced by a cheap and scalable electrodeposition procedure in aqueous media exhibit an extraordinary lithium storage capability at low temperature. These findings pave the way for more efficient, safer and faster charging of LIB-powered vehicles in regions with cold climates.
News & Events
Marco Musiani, research director at ICMATE CNR Padova, has been appointed Honorary Member of the International Society of Electrochemistry (ISE) by the Executive Committee of the Society, which has approved a proposal of the seven ISE Presidents in charge from 2005 to 2018. ISE Honorary Members are appointed primarily in recognition of their contribution to the Society. The ISE By-Laws limit to ten their maximum number, at any time.
Coatings (MDPI) dedicates the cover of the May issue to the article "Superhydrophobic Coatings from Recyclable Materials for Protection in a Real Sea Environment" written by ICMATE's researchers Dr. Michele Ferrari, Dr. Alessandro Benedetti and Dr. Francesca Cirisano.
The definition of the authenticity of artworks has undergone a slow process of development: with time, connoisseurship — the traditional practice of attributing detailed artistic identities to works of art on the basis of a comparative analysis of stylistic and formal components — has lost its position of technical leadership. In fact, currently, trust in the expert eye is increasingly subjected to the “objective” outcomes ensured by new and more rigorous techniques of scientific analysis of materials. However, this approach risks being somewhat reductive and incomplete.
THIS WEEK'S HIGHLIGHTS
Dust in fusion devices is still an open issue from the point of view of plasma operations and safety and due to its high fuel retention capability and mobility.
Thus, dust behaviour in such environments needs to be understood.
The analysis of this behaviour is both theoretical, focused on dust mobilization conditions, and experimental, aiming at mimicking these conditions.
New metallic materials or composites are studied and developed.
A unique combination of melting furnaces and metal working facilities (rolling, forging, drawing) allows laboratory-sized or small-sized production for subsequent testing or use in special application.
Numerous materials have been produced and characterised, among which titanium alloys, copper based foams, aluminium based composites, shape memory alloys, refractory alloys, precious metals, and biodegradable metals.
A relevant part of the research activity is focused on the optimization of innovative "wet chemistry" synthesis processes through three general approaches:
- nucleation and growth from solution
A first approach is based on the combination of hydrothermal treatments with oxalates co-precipitation. This approach has been used for the production of nanomaterials with interesting magnetic properties, in particular ferrites and manganites, with crystallite domains with average sizes ranging between 5 and 50 nm.
