At the Spring 2015 Materials Research Conference in San Francisco earlier this month, PATHION presented two new derivative superionic solid-state electrolytes built upon LiRAP (Lithium-Rich Anti-Perovskite). PATHION is working on a derivative for Li-sulfur batteries as well as a derivative that could be applied in a sodium-ion battery.

Prototype sodium silicate hydrogen generation system as presented earlier this year at DOE merit review. The H300 utilizes real-time swappable cartridges that generate hydrogen on demand using SiGNa’s proprietary sodium silicide (NaSi) powder. Sodium-Silica-Gel: 2Na-SG + H 2 O → H 2 + Na 2 Si 2 O 5.

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.

A team from the University of Science and Technology Beijing is proposing a new super-valent battery based on aluminium ion intercalation and deintercalation. Sodium-ion and magnesium-ion batteries, as new energy storage systems in portable devices, have attracted much attention of the investigators. Wang et al. Click to enlarge.

The work, performed by postdoc Vinodkumar Etacheri, Professor Vilas Pol and undergraduate chemical engineering student Chulgi Nathan Hong, is being presented at the 249 th American Chemical Society National Meeting & Exposition in Denver. These carbonaceous electrodes could also be used for rechargeable sodium-ion batteries.
