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. O 2 (NaNMC) cathode. in wt.).

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

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

The nanocrystals possess high and similar Li-ion and Na-ion charge storage capacities of 580?640 85% of the low-rate value, indicating that rate capability of Sb nanostructures can be comparable to the best Li-ion intercalation anodes and is so far unprecedented for Na-ion storage. 640 mAh g ?1

CMU study concludes lithium market fluctuations unlikely to impact Li-ion battery prices significantly

Green Car Congress

A new study by a team from Carnegie Mellon University’s College of Engineering has found that even large increases in lithium prices are unlikely to increase significantly the cost of batteries or battery packs for end users such as vehicle manufactures or consumers—although some manufacturers may see reduced profit margins.

Ragone plot of an NCCF-Acid/Na cathode together with two other representative Na-ion battery cathodes and lithium batteries. Sodium-ion intercalation batteries—i.e., Thus, insertion/deinsertion of sodium ions in a host material is much more difficult than that of lithium ions, the researchers note.
