PNNL team develops sodium-manganese oxide electrodes for sodium-ion rechargeable batteries

Green Car Congress

The resulting improved electrical capacity and recharging lifetime of the nanowires. Lithium-ion rechargeable batteries perform well, but are too expensive for widespread use on the grid. Sodium-ion batteries have been discussed in the literature. The nanowires were synthesized with a polymer-pyrolysis method.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

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.

Carnegie Mellon researchers develop semi-liquid lithium metal anode for use with solid electrolytes

Green Car Congress

Solid electrolytes are considered to be key components for next-generation lithium metal-based rechargeable batteries. The SLMA consists of lithium microparticles evenly distributed in a dual-conductive polymer matrix. The method used in this work has great potential for building reliable alkaline metal-based rechargeable batteries.
