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

Lux: Li-ion dominating grid storage market with 90% of 2014 proposals

Green Car Congress

Lithium-ion (Li-ion) batteries have become the dominant new technology in grid storage, capturing a 90% share of systems proposed last year, according to analysts at Lux Research. Li-ion accounted for 419 MW and 1,555 MWh of proposed storage systems in 2014. LFP, NMC are the leading Li-ion cathodes.

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. First, the nanodots provide additional storage capacity for lithium and speed up the charging and discharging process. Unlike graphite, MXenes can also intercalate sodium and potassium ions, notes Alshareef. Alhajji, E.,

Hollow carbon nanowires show high capacity and cycle life as anodes for sodium-ion batteries; insight into Na-ion insertion-extraction mechanism

Green Car Congress

Researchers at the Pacific Northwest National Laboratory have developed hollow carbon nanowires (HCNWs) for use as anode material for Na-ion batteries. The researchers attributed the good sodium-ion insertion properties to the short diffusion distance in the HCNWs and the large interlayer distance (0.37 Credit: ACS, Cao et al.
