New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

Penn State team uses 3D cross-linked polymer sponge to stabilize Li-metal anodes

Green Car Congress

Using metals as anodes in metal batteries is considered as the most promising approach to achieve high energy density in next-generation batteries, and it is applied in commercial low-cost batteries such as zinc (Zn) metal batteries and lead acid batteries. at a commercial-level areal capacity.

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

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 = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

New direct borohydride fuel cell increases peak power density by factor of 1.7–3.7

Green Car Congress

The new DBFC uses a polymer fiber membrane (PFM) rather than a polymer electrolyte membrane (PEM); metal oxides, such as LaNiO 3 and MnO 2 as cathode catalysts; and CoO as the anode catalyst. compared to classic DBFCs. DBFCs feature a high open circuit voltage (1.64 V), high fuel energy density (9.3 Wh·g -1 for NaBH 4 and 6.5
