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. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.
A team of researchers at the US Department of Energy’s Argonne National Laboratory has synthesized amorphous titanium dioxide nanotube (TiO 2 NT) electrodes directly grown on current collectors without binders and additives to use as an anode for sodium-ion batteries. V vs Li/Li + ) with comparable capacities to the dominant graphite anodes.
Tin (Sn) shows promise as a robust electrode material for rechargeable sodium-ion (Na-ion) batteries, according to a new study by a team from the University of Pittsburgh and Sandia National Laboratory. Rechargeable Na-ion batteries work on the same basic principle as Li-ion batteries—i.e., for the positive electrode.
Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance.
British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)
Cycling performance of Li/SeS 2 ?C, Researchers at Argonne National Laboratory have developed selenium and selenium–sulfur (Se x S y )-based cathode materials for a new class of room-temperature lithium and sodium batteries. Unlike the widely studied Li/S system, both Se and Se x S y can be cycled to high voltages (up to 4.6
The University of Texas at Arlington will develop acoustic stimulation and electrolytic proton production to produce lithium (Li) and nickel (Ni) from CO 2 -reactive minerals and rocks that contain calcium (Ca) and magnesium (Mg), while sequestering CO 2 in the form of carbonate solids. Travertine Technologies. from gangue minerals.
The Li-containing entropy-stabilized oxyfluoride (Li x (Co 0.2 V vs. Li + /Li, enabling its use as a cathode active material. The introduction of monovalent fluorine into the anion lattice of HEO, occupied by divalent oxygen, is charge compensated by incorporation of monovalent lithium (or sodium) into the cation lattice.
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. This is important in boosting the high-rate performance in both Li and Na ion storage.
This includes research on appropriate anodes, cathodes, and electrolytes for magnesium (Mg)-, sodium (Na)-, and lithium (Li)-based batteries and novel transition metal oxide- and nitride-based supercapacitor electrode materials. Magnesium is much more abundant in the Earth’s crust, making it less expensive than Li by a factor of 24.
A direct borohydride fuel cell—first demonstrated in the early 1960s—is a type of alkaline fuel cell directly fed by a sodium borohydride or potassium borohydride solution. Xiaodong Yang, Yongning Liu, Sai Li, Xiaozhu Wei, Li Wang & Yuanzhen Chen (2012). DBFCs feature a high open circuit voltage (1.64
The team is tuning this process so that it can be used to recycle any type of cathode materials used in lithium-ion and sodium-ion batteries. Pressure Relithiation of Degraded Li x Ni 0.5 —first author Yang Shi, who performed this work as a postdoc in Chen’s lab. 2019) “Ambient?Pressure O 2 (0 Adv. Energy Mater.
Under such a scenario, the production of Li-ion batteries should expand hugely over the years to come, hence reviving the issue of finite Li reserves. These reserves are indeed limited, but Li can be recycled by hydrometallurgy, although the economics of such a process has yet to be worked out. —Grey and Tarascon.
Chemical energy storage mainly includes lead-acid batteries, nickel batteries, lithium batteries, liquid flow batteries, and sodium-sulfur batteries, and electromagnetic energy storage mainly includes supercapacitor energy storage and superconducting energy storage. What is a battery?
First, SciAps has developed the LIBS (laser) Z-901 Lithium analyzer, purpose-built for measuring Li in rocks and brines, and the Z-902 Lithium analyzer with an extended spectrometer range for those users who need to additionally measure boron (B), magnesium (Mg), sodium (Na) and perhaps other metals in brines.
