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. Researchers are working on ways to store more energy in the cathode materials by increasing nickel content. —Bi et al.

New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

Researchers in Europe, with colleagues from Samsung R&D Institute in Japan, have developed a highly stable Fe 3 O 4 /C composite for use as a conversion electrode in all-solid-state Li-ion batteries. In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism.

Solid state Batteries v/s Li-ion Batteries: A Comparison Based on Cost

Get Electric Vehicle

To better understand the severity of the cost component, let us look at the cost comparison between Solid state and Li-Ion batteries. In a broad sense, the use of lithium-ion batteries that started the EV revolution has been the industry standard in the EV sector. Li-Ion Batteries: What Made Them The Most Desired?

UC Riverside team fabricates nanosilicon anodes for Li-ion batteries from waste glass bottles

Green Car Congress

Researchers at the University of California, Riverside’s Bourns College of Engineering have used waste glass bottles and a low-cost chemical process to fabricate nanosilicon anodes for high-performance lithium-ion batteries. An open access paper describing the research was published in the Nature journal Scientific Reports.

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al. Neither approach is practical.

ANL fluorinated cation electrolyte could help enable high-performance, long-lasting Li-metal batteries

Green Car Congress

To pre-store fluorine source on positive-charged species, here we show a cation that carries fluorine in its structure is synthesized and its contribution to interphasial chemistry is explored for the very first time. This combination is called an ionic liquid—a liquid consisting of positive and negative ions.

Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

The nanocrystals possess high and similar Li-ion and Na-ion charge storage capacities of 580?640 85% of the low-rate value, indicating that rate capability of Sb nanostructures can be comparable to the best Li-ion intercalation anodes and is so far unprecedented for Na-ion storage. 640 mAh g ?1
