U Waterloo team shows four-electron conversion for Li-O2 batteries for high energy density; inorganic molten salt electrolyte, high temperature

Green Car Congress

Chemists from the University of Waterloo have successfully resolved two of the most challenging issues surrounding lithium-oxygen batteries, and in the process created a working battery with near 100% coulombic efficiency. In addition, the superoxide consumes the organic electrolyte in the process, which greatly limits the cycle life.

Thermal Solar Goes Where PVs Can’t

Cars That Think

As electric utilities and policymakers seek solutions for storing and dispatching energy on demand, concentrating solar-thermal power (CSP) is once again gaining traction. Solar-thermal systems use sun-tracking mirrors to reflect sunlight onto a receiver, which contains a high-temperature fluid that stores heat. It's flexible.

Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. Sadoway is formally the Chief Scientific Advisor.

No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons. The gravity batteries described in this story lift giant weights in the air or up mine shafts to store excess electricity, releasing the weights later on to recover the stored energy.
