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 Na is comparable to graphite for standard lithium ion batteries.

Berkeley Lab team uses high-entropy mechanism to boost ionic conductivity in solid electrolyte

Green Car Congress

Experiments verify that high entropy leads to orders-of-magnitude higher ionic conductivities in lithium (Li)–sodium (Na) superionic conductor (Li-NASICON), sodium NASICON (Na-NASICON), and Li-garnet structures, even at fixed alkali content.

PNNL team develops sodium-manganese oxide electrodes for sodium-ion rechargeable batteries

Green Car Congress

To connect intermittent renewable energy sources (i.e., Sodium is seen by some as a promising alternative, but the sodium-sulfur batteries currently in use run at temperatures above 300 °C, making them less energy efficient and safe than batteries that run at ambient temperatures. Earlier post.) for some time. performance.

Univ. of Maryland team develops promising sodium-ion cathode material: FePO4/nanotube composite

Green Car Congress

Researchers at the University of Maryland have developed a nanocomposite material of amorphous, porous FePO 4 nanoparticles electrically wired by single-wall carbon nanotubes as a potential cathode material for sodium-ion batteries (SIBs). SWNT composite is a promising cathode material for viable sodium-ion batteries. C rate (10 mA/g).

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

These nanodots, roughly 10 nanometers wide, were connected to the MXene’s layers by carbon materials. Finally, strong connections between the nanodots and the layers improve the MXene’s conductivity and stabilize its structure during charging and discharging.
