PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. —Jin et al. 2 in mole or 1.6:8.4

UP Catalyst CO2-derived carbon nanotube electrode material boosts cycle life in Na-ion batteries

Green Car Congress

Tests conducted by Titirici Group , a multidisciplinary research team based at Imperial College London, have found that a novel carbon nanotube electrode material derived from CO 2 —produced by Estonian nanotech company UP Catalyst ( earlier post )—enhances the cyclability of sodium-ion batteries.

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.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

ppm) with a nominal Li/Mg selectivity >45 million. ppm) and an abundance of interfering ions (i.e., 13000 ppm of sodium, magnesium, calcium, and potassium ions, among others). Instead, the lithium concentration and the ratio of lithium to other multivalent ions, such as Mg 2+ and Ca 2+ , are the key factors to consider.

Sodium-Ion Powered EVs Roll off From Chinese EV Factories

Get Electric Vehicle

The first mass-produced electric vehicle (EV) using a sodium-ion battery has been introduced by JAC Motors. While lithium-ion batteries are more developed and have a higher density than sodium-ion batteries, sodium-ion batteries are cheaper, dependable, and have better cold-weather performance.
