Researchers at Shantou University and the Beijing Institute of Technology have developed a new nickel-based foam aimed at alleviating the shuttle effect, volume expansion, and other issues plaguing
Lu explained that the conversion of polysulfides is a complicated multiphase transformation during the charge-discharge period. The dissolvable lithium polysulphides diffuse through the porous separator to the negative electrode and react with Li metal to form non-dissolvable Li, causing a “shuttle effect” and leading to a deteriorative discharge capacity and cycling performance. This is one of the main defects seriously hindering the large-scale commercial applications of Li-S batteries.
“In past years, lots of effort has been devoted to the cathodes of lithium-sulphur batteries with excellent chemical adsorption of polysulphides and high catalytic efficiency. It is still an urgent issue to find a feasible strategy to integrate multiple respective functions to accelerate the conversion of the polysulphides,” Lu said.

Nickel debacle casts long shadow as industry masses in LondonThe ramifications of 2022's London Metal Exchange nickel trading debacle, including potential challenges to its nickel contract and the fate of the exchange itself will be hot topics next week as the metals industry descends on London. On March 8, last year, the 145-year old exchange was plunged into crisis - forced to halt nickel trading for the first time since 1988 - when prices more than doubled in a few hours to records above $100 000 a metric ton.
