Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

In order to enable fast-charging ability in batteries, researchers have attempted to enhance the mass transfer of electrolytes and charge transfer in electrodes, with extensive research carried out on the former compared to the latter. Generally, when charging surpasses rate of intercalation, Li + plating occurs on graphite electrodes.

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.
