U Texas team develops cobalt-free high-energy lithium-ion battery

Green Car Congress

More nickel in a battery means it can store more energy. graduate Wangda Li. codoped NMC (NMCAM) of identical Ni content (89 mol%) synthesized in?house. Ni NMA operates at a higher voltage by ?40 Ni NMA outperforms both NMC and NCA and only slightly trails NMCAM and a commercial cathode after 1000 deep cycles.

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.

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

Green Car Congress

The selected projects, led by universities, national laboratories, and the private sector aim to develop commercially scalable technologies that will enable greater domestic supplies of copper, nickel, lithium, cobalt, rare earth elements, and other critical elements. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals.

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

Green Car Congress

The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. 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. Elemental resources.

Nissan and Nissan Arc develop method for direct observation of electron activity in Li-ion cathode materials; L-edge X-ray absorption spectroscopy

Green Car Congress

In order to develop high-capacity, long-life lithium ion batteries, the maximum possible amount of lithium must be stored in the electrode’s active material, which allows it to generate the highest possible number of electrons. To develop such a material, an accurate reading of the electron activity inside the battery is essential.

BNL-led team finds electrolyte additive enables stable high-voltage cycling of nickel-rich layered cathodes

Green Car Congress

A team of researchers led by chemists at the US Department of Energy’s (DOE) Brookhaven National Laboratory has shown that using an appropriate amount of lithium difluorophosphate in a common commercial electrolyte enables stable cycling of nickel-rich layered cathode materials with an ultra-high cut-off voltage of 4.8?V.
