Silicon’s high theoretical charge capacity has inspired a tremendous amount of research into the possibility of using it to replace at least part of the graphite in lithium-ion battery anodes. However, Si presents major technical challenges. It can undergo a volume change of up to 300% during charging and discharging, limiting cycle life. Michigan-based Paraclete… Read more »

Tesla tweaks its battery chemistry: a closer look at silicon anode development
In mid-July, Tesla Motors made a trio of Model S update announcements. The new options included a 70 kWh rear-wheel-drive base model, an upgrade for the high-end battery pack from 85 to 90 kWh (providing about a 6% increase in range), and Ludicrous mode, which offers a 10% improvement in the car’s 0 to 60… Read more »
2016 Chevy Volt: GM’s top electrification engineers on designing the all-new EREV
When the Chevrolet Volt was launched at the end of 2010, I must confess that I gave it little chance of success. It seemed like an awkward compromise – buyers who wanted to go electric would surely prefer a pure EV, and buyers who weren’t ready to take that plunge had every reason to stick… Read more »
3M licenses NMC patents to LG Chem
3M and LG Chem have formed a patent license agreement to allow the Korean battery-maker to use 3M’s formulation of nickel manganese cobalt oxide (NMC) cathode materials in lithium-ion batteries. NMC, valued for its balance of power, energy, thermal stability and low cost, has been the subject of some rivalry and at least one lawsuit…. Read more »
Student-built EV sets world record for acceleration
What’s even faster than “ludicrous?” Ask students at Germany’s University of Stuttgart, who have set a new world record for acceleration. With observers from the Guinness Book of World Records looking on, the Green Team Formula race car shot to 100 kilometers per hour in 1.779 seconds – faster than a Formula One racer, or… Read more »
DOE offers funding for medium- and heavy-duty powertrain electrification projects
If you are working on a plug-in hybrid powertrain for medium- and heavy-duty vehicles, you may be eligible for a grant from the DOE. The agency plans to issue a new Funding Opportunity Announcement (DE-FOA-0001349) entitled “Medium and Heavy Duty Vehicle Powertrain Electrification and Dual Fuel Fleet Demonstration.” DOE anticipates releasing the FOA in August… Read more »
