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.

Testing shows Talga graphene silicon boosts capacity of Li-ion battery anode; Safevolt project

Green Car Congress

Australian advanced materials technology company Talga Resources Ltd announced positive initial test results from the development of its graphene silicon lithium-ion anode in the UK. The Safevolt project is an enabler for industry wanting higher Li-ion battery capacity above the level of standard graphite (exceeding maximum 372 mAh/g).

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.

Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.
