New cobalt-free high-voltage spinel cathode material with high areal capacity

Green Car Congress

. … It should be noted, the cost and sustainability of lithium-ion batteries are not only limited by the production of Co and Ni but also potentially limited by the lithium element itself. … The price of Co fluctuates significantly, with the inconspicuous fall of Ni price and continues growing of Li price. —Li et al. (a)

HIU researchers develop extremely high energy density lithium-metal cell with good stability

Green Car Congress

The team used a a promising combination of cathode and electrolyte: the nickel-rich cathode allows a large amount of energy per mass to be stored, while the ionic liquid electrolyte ensures that the capacity is largely retained over many charging cycles. The team reports on the lithium metal battery in an open-access paper in Joule.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

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. Haesun Park, Chung-Ang University, co-corresponding author.

Study finds resource constraints should not be a limiting factor for large-scale EV battery production

Green Car Congress

(A) Energy storage potential (ESP) based on annual production of the elements. On the order of 1 billion 40 kWh Li-based EV batteries could be built with the currently estimated reserve base of lithium, according to a recent study by researchers from Lawrence Berkeley National laboratory and the University of California, Berkeley.

Stanford researchers develop new electrolysis system to split seawater into hydrogen and oxygen

Green Car Congress

Existing water-splitting methods rely on highly purified water—a precious resource and costly to produce. Electrolysis of water to generate hydrogen fuel is an attractive renewable energy storage technology. However, grid-scale freshwater electrolysis would put a heavy strain on vital water resources.
