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.

Electrolysis of water to generate hydrogen fuel is an attractive renewable energy storage technology. The nickel foam acts as a conductor—transporting electricity from the power source—and the nickel-iron hydroxide sparks the electrolysis, separating water into oxygen and hydrogen.

A team at Argonne National Laboratory has used spatially resolved energy dispersive X-ray diffraction to obtain a “movie” of lithiation and delithiation in different sections of a Li-ion battery cell and to quantify lithium gradients that develop in a porous graphite electrode during cycling at a 1C rate (full discharge in 1 hour).

Layered lithium transition metal oxide cathodes feature a relatively high capacity, making them of importance for Li-ion batteries. Building a protective skin at both secondary and primary particle levels of layered oxides offers a promising design strategy for Ni-rich cathodes towards high-energy, long-life and safe lithium-ion batteries.

We need new storage technologies if more renewables are to be used on the electrical grid; similarly, the electrification of transport requires much cheaper and longer-lasting batteries. 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.

Taking advantage of the elemental, chemical and surface sensitivities of soft X-rays, they reported, in an open access paper in Nature Communications , distinct lithium-ion and electron dynamics in Li(Co 1/3 Ni 1/3 Mn 1/3 )O 2 and LiFePO 4 cathodes in polymer electrolytes. This research was performed at beamline 8.0.1
