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

Green Car Congress

Their findings could pave the way for improved battery designs with increased capacity, stability, and safety for both mobile devices and electric vehicles. Solid-state lithium batteries comprise solid electrodes and a solid electrolyte that exchange lithium (Li) ions during charging and discharging. O 4 and Li 2 Ni 0.5

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. 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. … —Li et al. (a) —Li et al. Earlier post.).

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.

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