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.

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. . …

Researchers show clean solid–electrolyte/electrode interfaces double capacity of solid-state Li batteries

Green Car Congress

Solid-state lithium batteries comprise solid electrodes and a solid electrolyte that exchange lithium (Li) ions during charging and discharging. Their higher energy density and safety make SSLBs very attractive as next-generation sstorage solutions. O 4 are promising power supplies for mobile devices and electric vehicles.

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

Green Car Congress

Scientists at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) report new findings about how to make a single-crystal, nickel-rich cathode hardier and more efficient. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

IDTechEx comments on Volkswagen’s long-term, high-manganese cathode strategy

Green Car Congress

During Volkswagen’s recent Power Day ( earlier post ), the company referred to a long-term strategy of using high-manganese cathodes for its volume segment. A comparison between NMC 811 and three high-manganese cathodes (LMFP, Li-Mn-rich, LNMO) shows that trade-offs in performance are always involved. Source: IDTechEx.

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. Nat Energy. The LiNi 0.5 mA cm −2 ).
