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

Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. Sodium (Na) is an earth-abundant and inexpensive element, and shares many properties with lithium.

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

Green Car Congress

The Carnegie Mellon University researchers, whose study was published in the Journal of Power Sources , analyzed multiple lithium-ion battery chemistries and cell formats to see whether extreme lithium price variations would have a substantial impact. per kg of Li 2 CO 3 ) do not change the cost of lithium-ion cells by more than 10%.

Purdue researchers convert packing peanuts into anode materials for Li-ion batteries; outperforming graphite

Green Car Congress

Purdue researchers have developed a process to manufacture carbon-nanoparticle and microsheet anodes for Li-ion batteries from polystyrene and starch-based packing peanuts, respectively. These carbonaceous electrodes could also be used for rechargeable sodium-ion batteries. Batteries'

Researchers use in situ NMR spectroscopy to provide insight into silicon expansion in Li-ion batteries

Green Car Congress

A major barrier to the use of high energy capacity silicon in a lithium-ion battery is the volumetric expansion of silicon under lithiation and delithiation, which results in electrode degradation and capacity fade. Silicon (shown in grey) is capable of holding 10 times as many lithium ions (shown in pink) as currently-used anodes.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

The circulating seawater in the open-cathode system results in a continuous supply of sodium ions, endowing the system with superior cycling stability that allows the application of various alternative anodes to sodium metal by compensating for irreversible charge losses. an alloying material), in full sodium-ion configuration.

High-capacity GQD-coated VO2 nanoarray electrodes for high-performance Li- and Na-ion batteries

Green Car Congress

Researchers from Nanyang Technical University (NTU) in Singapore have shown high-capacity, high-rate, and durable lithium- and sodium-ion battery (LIB and NIB) performance using single-crystalline long-range-ordered bilayered VO 2 nanoarray electrodes. VO 2 nanobelts are beneficial to fast ion diffusion. Credit: ACS, Chao et al.
