New research from the University of California San Diego has found one of the causes of voltage fade in lithium-rich layered oxides (LRLO). LRLO is a promising candidate as a cathode material as it can provide 50% more capacity than current alternatives. However, voltage fade reduces the energy capacity of this material over time. UC… Read more »

ZapGo’s Carbon-Ion tech combines power density of supercapacitors and energy density of batteries
Williams Advanced Engineering has selected ZapGo, a spinout of Oxford University, to join a consortium working to develop next-generation battery systems for EVs (part of the UK government’s Faraday Battery Challenge). ZapGo’s Carbon-Ion technology, based on carbon nanomaterials including graphene, is intended to combine the power density of supercapacitors and the energy density of rechargeable… Read more »
Iron trifluoride cathode could greatly increase energy density
Researchers from the University of Maryland and the DOE’s Brookhaven National Laboratory have developed a cathode material containing iron trifluoride (FeF3) that they say could triple the energy density of Li-ion batteries. Their research was published in Nature Communications. “Compared to the large capacity of the commercial graphite anodes used in lithium-ion batteries, the capacity of the cathodes is… Read more »
Wildcat sorts through the avalanche of new battery materials to find the best
As automakers and cell manufacturers begin to realize the complexity of benchmarking new battery materials, Wildcat Discovery Technology is using its high-speed R&D technology to help find clarity If you follow battery technology news on a regular basis as we do, it’s easy to get overwhelmed by the volume of new announcements. There are… Read more »
Adding graphene girders to silicon electrodes could double battery life
Graphite has long been the default choice of material for anodes, but researchers dream of replacing graphite with silicon, which has ten times the gravimetric energy density. Unfortunately, silicon has several issues that limit its commercial use – it expands during lithiation, causing particles to agglomerate in ways that impede efficiency, and it is not… Read more »
Recycling worn cathodes to make new batteries
As lithium-ion batteries proliferate, the question of what to do with them when they wear out is becoming a major environmental concern. Less than five percent of used batteries are recycled today. Nanoengineers at the University of California San Diego have developed an energy-efficient recycling process that restores used cathodes from spent batteries and makes… Read more »
Revolutionary continuous mixing process for producing Li-ion electrode slurries: Lower costs and higher quality
Sponsored by Bühler By Dr. Adrian Spillmann, Head of Market Segment Battery Solutions with Grinding & Dispersion Technologies at Bühler The manufacturers of lithium-ion batteries are currently in the process of massively expanding their global capacity. These investments are being driven by rising demand for electric vehicles, among other things. By 2025, the market for such vehicles… Read more »
AKASOL Li-ion systems now powering Medatech’s underground mining equipment
Emissions in underground mining are not only a hazard to workers’ health – they are expensive to mitigate. Diesel-powered drilling, anchoring and transport machines produce exhaust gases that have to be siphoned off by large ventilation units via purpose-built shafts, a laborious and cost-intensive proposition. One solution is to rely on electrically powered machines, which… Read more »
DOE awards $6 million to first crop of Battery500 Seedlings
The Battery500 consortium, led by the DOE’s Pacific Northwest National Laboratory (PNNL), intends to build a battery pack with a specific energy of 500 Wh/kg, which would more than double the 170-200 Wh/kg per kilogram in today’s typical EV battery. Part of the initiative is the “Seedling” program, which identifies new and risky battery research… Read more »
Saft team develops first metal hydride-sulfur battery
Researchers at French battery-maker Saft and Université Paris Est have, for the first time, used a nanocomposite metal hydride as the anode in a complete solid-state battery with a sulfur cathode and LiBH4 electrolyte. In “An all-solid-state metal hydride-Sulfur lithium-ion battery,” published in the Journal of Power Sources, Pedro López-Aranguren and colleagues explain that their… Read more »
