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.

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.

EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think!

Plug In India

Video: EV Guru: Sodium-Ion Batteries are Coming Sooner Than You think! The mining industry cannot keep up with the demand, so the alternative is to manufacture batteries based on sodium chemistry. The big issue with sodium-ion batteries is that they can store only about two-thirds of the energy of Li-ion batteries of equivalent size.
