Researchers in Korea propose graphene/Ni foam as Li metal storage medium for advanced batteries

Green Car Congress

Researchers in Korea have developed three-dimensional monolithic corrugated graphene on nickel foam electrode as a Li metal storage framework in carbonate electrolytes. Therefore, hybrid engineering to prevent dendritic Li growth and increase the coulombic efficiency in highly reactive electrolytes is essential. —Kang et al.

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.

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

Green Car Congress

Researchers from the Cockrell School of Engineering at The University of Texas at Austin have developed a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways. More nickel in a battery means it can store more energy.

UC Irvine team creates long-lasting, cobalt-free, low-nickel lithium-ion batteries

Green Car Congress

In a discovery that could reduce or even eliminate the use of cobalt—which is often mined using child labor—in the batteries that power electric cars and other products, scientists at the University of California, Irvine (UCI) have developed a long-lasting alternative made with nickel. The LiNi 0.5 mA cm −2 ). Nat Energy.

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

Green Car Congress

The paper on their work is published in the Journal of Power Sources. Advancing cathode materials with both high energy density and low cost have always been the main objective of battery material research. The price of Co fluctuates significantly, with the inconspicuous fall of Ni price and continues growing of Li price. . …
