Allegro MicroSystems expands gate driver portfolio to simplify 800 V SiC power design
Allegro MicroSystems has released its AHV85003 and AHV85043 isolated gate driver chipset, expanding its Power-Thru isolated gate driver portfolio. This chipset joins Allegro’s existing AHV85311 integrated solution, forming a product ecosystem for high-voltage silicon carbide (SiC) designs in EVs, data centers and other systems. Allegro says that this new offering addresses the challenge of power… Read more »
Volt Carbon reports second US patent and new lithium battery test results
Canadian lithium battery developer Volt Carbon Technologies has received a second United States patent for its dry-separation graphite platform and reported new technical results from its lithium battery development program. Volt Carbon has received its patent titled “Method and System for Aerodynamic Air Classification” from the United States Patent and Trademark Office, issued as USPTO… Read more »
Research from ANL and UChicago PME looks to resolve battery degradation by mitigating nanoscopic strains
New research from Argonne National Laboratory and the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) claims to have solved a battery mystery that has led to capacity degradation, shortened lifespan and, in some cases, fire. In a paper published in Nature Nanotechnology, researchers uncovered some of the root causes and ways to… Read more »
Molabo’s new 48 V serial hybrid system for boats features Fischer Panda generators
Molabo, a German manufacturer of high-performance 48 V electric propulsion systems, has unveiled a new serial hybrid system that integrates its low-voltage ARIES drive with Fischer Panda’s lightweight and compact AGT-series generators. Developed for Team Malizia’s IMOCA racing yacht, the new hybrid system allows boatbuilders to combine electric operation and generator-assisted cruising, offering flexible and… Read more »
Operando X-ray tomography reveals silicon-electrolyte interface dynamics in solid-state batteries
Silicon anodes can greatly boost the energy density of all-solid-state batteries, but their large volume changes often cause contact loss with solid electrolytes. Si can store more lithium than graphite, but its volume can expand by as much as 410% during charging, generating mechanical stress that cracks particles and weakens their contact with the solid… Read more »
Altech demonstrates safety of sodium-nickel-chloride batteries under destructive test conditions
Solid-state battery developer Altech Batteries has completed a full suite of safety self-destruction validation tests on its sodium-nickel-chloride (SNC) battery technology, which it recently began selling. The tests were designed to simulate the most severe field hazards that can occur during storage, transport or operation. Across all the scenarios, which included direct fire exposure, rod… Read more »
NEO receives order to supply batteries for drones
Canada-based NEO Battery Materials has received its first purchase order valued at C$4.5 million ($3.2 million) over three years and secured a joint development agreement for high-performance battery products from an Asian manufacturer specializing in mission flight control systems for drones and unmanned aerial vehicles (UAVs). Under the agreement, NEO will design and manufacture two… Read more »
Convenience store chain Sheetz selects Driivz to power its EV charging network
US convenience store chain Sheetz has selected EV software supplier Driivz, a Vontier company, to power its growing EV charging network with EV charging and energy management software. Sheetz already offers EV charging at more than 125 sites across seven states through third-party operators. However, like a certain other large retail chain, Sheetz has decided… Read more »
Argonne scientists develop protective coating to boost solid-state battery stability
Researchers at the US Department of Energy’s Argonne National Laboratory have developed a method to coat sulfide-based solid electrolytes to improve chemical stability and reduce manufacturing costs. The process uses atomic layer deposition (ALD) to apply a protective layer of aluminum oxide onto the electrolyte particles. This coating improves stability by acting as a shield… Read more »
