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 V vs graphite, at 1 C, 1.5 mA cm

Novel molecular orbital interaction stabilizes cathode materials for lithium-ion batteries

Green Car Congress

An international team led by scientists from the Institute for Superconducting and Electronic Materials at the University of Wollongong in Australia has verified that the introduction of novel molecular orbital interactions can improve the structural stability of cathode materials for lithium-ion batteries.

Sandia testing method yields pathway to better, longer-lasting solid-state batteries

Green Car Congress

The contributions from ions, electrons, and interfaces are deconvolved by correlating the CPD profiles with Li-concentration profiles and by comparisons with first-principles-informed modeling. In our case, it really has to do a lot with how fast lithium ions can move in the Si anode used in the study.

Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. 35 °C, the reversible capacity is still effectively retained at 160 mAh g –1 after 200 cycles. An open-access paper on the work is published in ACS Central Science.

Ilika leading £8M project on high silicon content electrode SSBs for EVs

Green Car Congress

Solid state batteries with their solid electrolyte are expected to provide greater safety and performance in comparison to lithium-ion batteries which presently power electric vehicles and have a liquid electrolyte. Ilika will receive a grant of £2.8 BMW Group and WAE Technologies will join the project’s steering committee.

Uppsala U team identifies main performance bottlenecks in Li-sulfur battery performance

Green Car Congress

Lithium-sulfur batteries are prospects for future batteries as they are made from cheaper and more environmentally friendly materials than lithium-ion batteries. In this work, simultaneous measurements of small-angle and wide-angle scattering and cell resistance are performed on operating lithium-sulfur cells.

UCL, UI researchers devise method to optimize magnesium chromium oxide cathode materials; disordered materials

Green Car Congress

University College London and University of Illinois at Chicago researchers report a new, scalable method for making a material that can reversibly store magnesium ions at high-voltage. One factor limiting lithium-ion batteries is the anode. —Professor Jordi Cabana (University of Illinois at Chicago).
