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

Green Car Congress

Anodic half-cells with the novel binder delivered a discharge capacity of 73 mAh/g at 10 C, which is three times higher than the those of the polyvinylidene fluoride (PVDF) and sodium carboxymethyl cellulose/polystyrene-polybutadiene rubber (CMC-SBR) counterparts, with a high capacity retention for more than 1000 cycles. —Pradhan et al.

EVs with sodium-ion batteries are rolling off production lines in China – Charged EVs

Baua Electric

Sodium-ion batteries have long been touted as a possible successor to the lithium-ion kind—they may have lower energy density, but they rely on more abundant sodium rather than lithium, perform better in cold temperatures, and above all, tend to be cheaper. kWh and a range of 301 km (CLTC).
