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.

Researchers show that layered calcium transition metal oxides can be promising cathode materials for Ca-ion batteries

Green Car Congress

Out of several candidates that could replace Li in rechargeable batteries, calcium (Ca) stands out as a promising metal. Not only is Ca 10,000 times more abundant than Li, but it can also yield—in theory—similar battery performance. Haesun Park, Chung-Ang University, co-corresponding author.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)

Amorphous titanium dioxide nanotube anodes for sodium-ion batteries show ability to self-improve specific capacity

Green Car Congress

A team of researchers at the US Department of Energy’s Argonne National Laboratory has synthesized amorphous titanium dioxide nanotube (TiO 2 NT) electrodes directly grown on current collectors without binders and additives to use as an anode for sodium-ion batteries. V vs Li/Li + ) with comparable capacities to the dominant graphite anodes.

ARPA-E awarding $39M to 16 projects to grow the domestic critical minerals supply chain

Green Car Congress

The projects were selected as part of ARPA-E’s Mining Innovations for Negative Emissions Resource Recovery (MINER) program. Feedstocks will include Li/Ni/Ca/Mg-rich igneous and sedimentary minerals. The technology has been proved for copper-sulfide minerals, which will improve the yields of Cu and ultimately Ni.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. Under such a scenario, the production of Li-ion batteries should expand hugely over the years to come, hence reviving the issue of finite Li reserves. Elemental resources.
