Donald R. Sadoway – a prominent member of The Electrochemical Society and electrochemist at the Massachusetts Institute of Technology in Cambridge – has led a team of researchers at MIT to improve a proposed liquid battery system that could help make sources of renewable energy more viable and prove to be a competitor for conventional power plants.

This from MIT News:

Sadoway, the John F. Elliott Professor of Materials Chemistry, says the new formula allows the battery to work at a temperature more than 200 degrees Celsius lower than the previous formulation. In addition to the lower operating temperature, which should simplify the battery’s design and extend its working life, the new formulation will be less expensive to make, he says.

Recently some researchers move to Mg batteries. Pellion Tech in its white paper claims double energy density both in volumetric and gravimetric for Mg batteries.

I am confused since it seems that the discharge voltage should be at least 3V and no cell have been reported working experimentally at such potential yet (Maybe I did not find).

Moreover, the safety issues will not come for Mg batteries with magnesium anodes? and for Mg-ion batteries, the energy density would be competitive with current Li-ion batteries?

Does the main opportunity for Mg batteries lie in their cathodes same as Lithium batteries?

This focus issue will cover state-of-the-art efforts that address a variety of approaches to printable functional materials and devices.

Printing technologies in an atmospheric environment offer the potential for low-cost and materials-efficient alternatives for manufacturing electronics and energy devices such as luminescent displays, thin film transistors, sensors, thin film photovoltaics, fuel cells, capacitors, and batteries.

Significant progress has been made in the area of printable functional organic and inorganic materials including conductors, semiconductors, dielectric, and luminescent materials

These will enable exciting advances in printed electronics and energy devices. Some examples are printed amorphous oxide semiconductors, organic conductors and semiconductors, inorganic semiconductor nanomaterials, silicon, chalcogenide semiconductors, ceramics, metals, intercalation compounds, and carbon-based materials.

This focus issue will cover state-of-the-art efforts that address a variety of approaches to printable functional materials and device. The focus issue will include both invited and contributed papers reflecting recent achievements. Prospective authors are encouraged to submit contributions reporting the original research results or reviewing key emerging trends in printable functional materials and devices for publication in this focus issue.
