French researchers develop sodium-ion battery in 18650 format; performance comparable to Li-ion

Green Car Congress

Researchers within the RS2E network on electrochemical energy storage (Réseau sur le stockage électrochimique de l’énergie) in France have developed the first sodium-ion battery in an 18650 format. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. It is a variation of a sodium-metal halide battery. of peak charge capacity.

CATL launches “condensed battery” with an energy density of up to 500 Wh/kg for aircraft; automotive version this year

Green Car Congress

CATL also says it can achieve mass production of condensed battery in a short period of time. CATL said it will also launch the automotive-grade version of condensed batteries, which are expected to be put into mass production within this year. These have been used on multiple high-end BEVs such as ZEEKR, AITO and Li Auto.

Study identifies halogen-free superhalogen electrolytes for Li-ion batteries

Green Car Congress

Most electrolytes currently used in Li-ion batteries contain halogens, which are toxic. An in-depth study based on first-principles calculations by researchers at Virginia Commonwealth University has shown that the anions of commercially available electrolytes for Li-ion batteries are all superhalogens.
