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

New class of coordination polymers for high-performance Li-, Na- and K-ion storage

Green Car Congress

Coordination compounds are molecules that possess a metal center bound to ligands (atoms, ions or molecules that donate electrons to the metal); these complexes can be neutral or charged. V in lithium-, sodium-, or potassium-based cells. V for Li-, Na- and K-ion batteries. V for Li-, Na- and K-ion batteries.

WSU, PNNL researchers develop viable sodium battery

Green Car Congress

Although O3-layered metal oxides are promising cathode materials for high-energy Na-ion batteries, they suffer from fast capacity fade. However, the nickel rich O3-NaTMOs suffer from irreversible phase transition at high voltage and limited cycle life, similar to their Li analogues, if not even worse.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. The gliding occurs as the battery charges and discharges—lithium ions depart and return to cathode, straining the crystal ever so slightly each time.

Siloxene as promising silicon intercalation anode for Li-, Na- and K-ion batteries

Green Car Congress

Researchers in France have shown the versatility of siloxene, a 2D silicon structure (Si 6 O 3 H 6 ), as an anode material for Li-, Na- and K-ion batteries. It is one of the most promising anodes for lithium-ion (LIB) and sodium-ion (NIB) batteries due to its high theoretical capacity 3590 mAh/g for Li 15 Si 4 and 954 mAh/g for NaSi.

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.

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
