Faraday Institution develops ultrasonic recycling method
Faraday Institution researchers working on the recycling of lithium-ion batteries at the Universities of Leicester and Birmingham have developed a new method to recover materials from end-of-life EV batteries. The new process uses ultrasonic waves to separate valuable material from the electrodes. The researchers say it delivers a higher purity of recovered materials compared to… Read more »
Ultra-high purity lithium salt, LiFSI, facilitates high performance in advanced battery technology
Sponsored by Arkema The lithium-ion battery market is demanding higher energy density, extended lifetime, and improved power performance. Arkema’s Battery Solutions address many of these demands. Advances in electrode materials are addressing energy density, while new electrolyte systems can significantly improve lifetime and power performance. LiFSI, in particular, is a good candidate to replace LiPF6,… Read more »
OneD unveils new silicon-based battery technology
OneD Battery Sciences has introduced SINANODE, a technology to power the next generation of silicon-based EV batteries. The SINANODE process fuses silicon nanowires onto commercial graphite powders, which the company says triples the energy density of the anode while cutting its cost per kWh in half. The higher energy density increases battery range while nanowires… Read more »
Wildcat ramps up its focus on EV Supercell breakthroughs
The lithium-ion battery has proven to be an excellent fuel tank for EVs, but there remains much room for improvement. We’re still far from what’s theoretically achievable in terms of Li-ion capacity, safety, cost and charge times. As battery manufacturers continue their quest for improved chemistry and material combinations, they rely on applied researchers like… Read more »
Leclanché develops 65 Ah lithium-ion pouch cell for EVs
Leclanché has developed a new high-energy 65 Ah lithium-ion pouch cell to meet the demands of bus and truck manufacturers seeking increased EV range and operating time. The new GL 65 Ah G/NMC (graphite/nickel manganese cobalt oxide) cells are specially designed for energy-intensive applications. They provide 10% more energy and feature a 10% increase in… Read more »
Battery recycling startup receives financing for commercial-scale plant
Battery Resourcers, a battery recycling and manufacturing company, recently completed a $20-million Series B equity round to support the development of a commercial-scale processing facility with the annual capacity to recycle 10,000 tons of batteries—roughly the amount of batteries from 20,000 EVs. Battery Resourcers’ approach to battery manufacturing starts with a mixed stream of used… Read more »
GM unveils production version of Cadillac Lyriq EV
GM has taken another step toward its vaunted all-electric future, unveiling what it says is a production version of the 2023 Cadillac Lyriq EV. Its design and specs appear to be pretty close to those of the original prototype that GM unveiled last year. The Lyriq will be the first vehicle to use GM’s new… Read more »
Wildcat develops new device to measure battery electrode thickness during cycling
Wildcat Discovery Technologies, a creator of high-throughput methods to rapidly design new battery materials, has developed a new Linear Displacement Measurement (LDM) Device that measures small thickness changes in pouch cells during cycling. Developed in partnership with BMW, Wildcat’s LDM capability allows new cell performance feedback as parts of projects with its collaboration partners. Measurements… Read more »
New paper shows atomic-scale closeups of how a lithium-metal electrode ages
Lithium-metal batteries, which use anodes made of lithium metal rather than graphite, could offer great improvements in energy density and weight. The DOE’s Battery 500 Consortium has set a goal of developing lithium-metal EV batteries with triple the energy density of today’s Li-ion cells. Now scientists at Stanford University and the SLAC National Accelerator Laboratory… Read more »
