PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

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.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

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.

New direct borohydride fuel cell increases peak power density by factor of 1.7–3.7

Green Car Congress

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

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

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.

Take a detailed look at 7 types of energy storage batteries

Setec Powerr

With the worldwide emphasis on renewable energy sources such as solar and wind, energy storage has become an essential solution for grid stability and reliability. At a certain working degree, sodium ions pass through the reversible reaction between the electrolyte diaphragm and sulfur to form the release and storage of energy.
