The quest for the better battery involves ongoing research on improving and optimizing materials used for lithium-ion cells. One such material is LiMn2O4 (LMO), which offers high power and low cost, but cell life at high temperatures can be problematic. In a paper in Nano Letters, a team from the Ulsan National Institute of Science… Read more »

Virgin and Venturi racing teams round out Formula E roster
Two high-profile groups have announced plans to field teams for Formula E, the all-electric racing series that will take place in 10 city centers around the world, beginning in Beijing in September 2014. The Virgin Racing and Venturi teams became the ninth and tenth to join, making the roster complete. Sir Richard Branson’s Virgin empire… Read more »
MIT team uses virus to make a better lithium-oxygen battery
Researchers around the world have taken up the quest for a better battery, and lithium-air is one of the many promising routes to the Grail. This week, a team from MIT described an improved way to make nanowires for a lithium-air battery electrode using – of all things – viruses. “Biologically enhanced cathode design for… Read more »
IBM, Honda and PG&E team up to develop smart charging for EVs
The pilot system will let an EV receive and respond to charge instructions based on the grid condition and the vehicle’s battery state, so energy providers can manage charging during peak hours.
Prologis to build two electric truck charging hubs in Southern California
Logistics real estate specialist Prologis has unveiled two upcoming electric truck charging installations as part of its Prologis Mobility platform. The two charging sites will enable Performance Team, a national logistics company, to simultaneously charge up to 38 of its Volvo VNR Electric Class 8 battery-electric trucks. Prologis manages some 1.2 billion square feet of… 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 »
How software-in-the-loop testing accelerates e-mobility: virtual validation for real innovation
Sponsored by dSpace. Electromobility is evolving rapidly. New vehicle concepts, complex E/E architectures, and increasingly powerful battery systems are pushing developers to their limits. At the same time, the pressure to shorten development cycles and reduce costs is growing. In this dynamic environment, one method is gaining significant traction: Software-in-the-Loop (SIL) testing. What Is Software-in-the-Loop Testing?… 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 »
