In a study published in the Journal of Power Sources, researchers from the Karlsruhe Institute of Technology (KIT) have demonstrated that there are significant changes to the thermal transport properties of battery anodes and cathodes dependent on the aging conditions. The effective thermal diffusivity of the electrode stack and thermal conductivity of the active materials… Read more »

NYC deploys 60 more electric buses, adds more charging infrastructure
New York City’s Metropolitan Transportation Authority (MTA) has introduced 60 new electric buses that will operate in routes in Queens, Staten Island and Brooklyn. The MTA currently operates 15 electric buses on routes in Manhattan. It expects to start receiving its next order of 205 electric buses in late 2025, and is also negotiating an… Read more »
Sakuu manufactures lithium metal cell using dry process
US solid-state battery specialist Sakuu has produced its lithium metal Cypress battery cell using a fully dry process. The company has now produced commercial-grade lithium-metal anode battery cells using both wet and dry electrode manufacturing. The batteries can run for 1,000 cycles at 100% depth of discharge (DoD) to 80% state of health (SOH), providing… Read more »
Researchers demonstrate selective recovery of lithium from spent lithium iron phosphate batteries
A team from the Beijing University of Chemical Technology has used a formic acid-hydrogen peroxide system for selective leaching of lithium ions from spent lithium iron phosphate batteries. A paper on their process was published in the Journal of Power Sources. The team achieved optimal leaching conditions by single-factor optimization: formic acid concentration of 0.8… Read more »

QuantumScape is developing solid-state lithium-metal battery technology that promises significant performance improvements compared to current lithium-ion cells. Now the company has started customer shipments of Alpha-2 prototype battery cells, a significant milestone on the road to delivery of its first planned commercial product, called QSE-5. QuantumScape’s Alpha-2 prototypes integrate many significant component improvements made over… Read more »
Stellantis Ventures invests in Tiamat’s sodium-ion battery technology
Stellantis Ventures has made a strategic investment in France-based sodium-ion battery developer Tiamat. Tiamat says its sodium-ion technology is lithium- and cobalt-free and cheaper per kilowatt hour (kWh) when compared with lithium-ion batteries. The wide availability of sodium boosts sustainability and material sovereignty. Tiamat will use the new funding to start construction of a sodium-ion… Read more »
Range Energy’s electrified semi-trailer now eligible for up to $120,000 incentive through California’s CORE Project
Range Energy makes electrified semi-trailers for the heavy-duty freight market. Range’s trailer, which is equipped with a battery pack (up to 300 kWh), an electric motor and (as a bonus) off-road mobile power, can be used with any semi-tractor, and the company says it can double the fuel mileage of a diesel rig while cutting… Read more »
How Umicore is ensuring sustainability in the North American EV battery chain
Q&A with Umicore’s Robert Privette Umicore traces its roots to a Belgian mining company formed in 1906. Since then, it has moved on from mining to a variety of high-tech pursuits including refining, recycling and the manufacture of specialized metal products. Today it’s one of Belgium’s largest companies, and has a strong presence in e-mobility,… Read more »
Battery-integrated chargers offer a cure for America’s weak electric infrastructure
Q&A with Alex Urist, Vice President of XCharge North America Battery storage, once considered a nifty additional feature for large-scale charging infrastructure projects, is steadily becoming de rigueur for public and commercial charging deployments of all sizes. Adding batteries to the system offers several benefits: coupled with on-site generation, it allows charging to be offered… Read more »
Battery cell qualification for EVs: Lucid’s cell specialist discusses the complicated process
Q&A with Lucid’s Battery Cell Technical Specialist Maithri Venkat. When it comes to battery cells for EVs, one size definitely doesn’t fit all. The properties of a particular cell act as constraining factors for every aspect of a vehicle’s design—and not only for vehicle performance parameters such as range and power, but for the development… Read more »
