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.

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.

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.

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?

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. Tutusaus, O.,

RPI researchers develop new aqueous Li-ion battery that improves safety without sacrificing performance

Green Car Congress

As the lithium-ion batteries that currently power most phones, laptops, and electric vehicles become increasingly fast-charging and high-performing, they also grow increasingly expensive and flammable. Moreover, the battery could be cycled at high rates; increasing the charge/discharge rate by an order of magnitude (0.5C–5C)
