Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 100 to 150 mA h g ? 100 to 150 mA h g ?1 —Sun et al.

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.

Univ. of Tokyo researchers demonstrate new “oxygen-rocking” battery

Green Car Congress

Researchers at the University of Tokyo have developed a battery based on the concept of a combination of a perovskite-type cathode and a low-electrode-potential anode that can achieve high energy densities through the use of organic rather than aqueous electrolytes. Earlier post.). —Hibino et al. under milder conditions than usual.

Antimony/carbon nanocomposite anode for Na-ion battery shows high capacity and stability

Green Car Congress

Researchers at Wuhan University (China) have synthesized a Sb/C (antimony/carbon) nanocomposite for use as an anode material in a room-temperature sodium-ion (Na-ion) battery. A sodium disk served as the counter and reference electrode. Source: Yang et al. Click to enlarge.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example). The kraft process converts wood into wood pulp for paper production.
