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.

Researchers improve the performance of sodium-ion batteries by using tailored carbon anodes with hierarchical porosity

Green Car Congress

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials. 1 at C/5 while exhibiting excellent rate capability and reasonable cycle life.

Tsinghua researchers conclude surging lithium price will not impede EV boom

Green Car Congress

Although the current 10-fold price spike of lithium is giving the electric vehicle market a sharp short-term shock, a study by a team from Tsinghua University indicates that it will not hinder transportation electrification in the long run. In comparison, only 40% of global oil supply clusters in the top 3 producing countries.
