Envia wins $7.7 million contract to develop advanced cathode and anode materials
The US Advanced Battery Consortium (USABC), a collaboration among the Big Three US automakers, has awarded a $7.7-million battery technology development contract to Envia Systems of Newark, California. The competitively bid contract, which is co-funded by the DOE and includes a 50 percent Envia Systems cost-share, is for a 36-month program that will focus on… Read more »
Pomegranate-style anode could lead to next generation of batteries
The big buzz on the EV tech scene these days is about silicon anodes, which could offer ten times more storage capacity than carbon anodes. Scientists around the world are looking for ways to overcome the remaining obstacles to using silicon for a new generation of lithium-ion batteries. Researchers at Stanford University and the DOE’s… Read more »
Cambridge researchers get a close-up view of silicon expansion in Li-ion batteries
Researchers have been interested in silicon as a replacement for carbon in battery anodes for many years, as it has roughly ten times more storage capacity. However, there’s also a tragic flaw: silicon atoms absorb lithium atoms, causing the silicon to expand up to three times in volume, degrading the battery. Now a team at… Read more »
CalBattery’s new SiGr anode material hopes to break the battery bottleneck
California Lithium Battery took advantage of national and local government programs so it could focus on its revolutionary silicon-graphene anode material. Now with EV, electronics, and energy storage customers lining up, it hopes to break the battery bottleneck. When you think about a bottleneck, you think about constriction – something that moves in a particular… Read more »
Silicon nanowire batterymaker Amprius raises $30 million in Series C funding
Amprius, a developer of lithium-ion batteries using silicon anodes, has raised $30 million in a Series C funding round, which it will use to commercialize its batteries and further develop the next generation. The company introduced its first generation of batteries in May 2013, and is supplying smartphone and tablet OEMs with its first two… Read more »
CalBattery’s new Si-graphene anode triples Li-ion battery capacity
California Lithium Battery, a finalist in the DOE’s 2012 Start Up America’s Next Top Energy Innovator challenge, has announced the record-setting performance of its new “GEN3” silicon graphene composite anode material for lithium-ion batteries (LIBs). Independent test results in full cell LIBs reveal an energy density of 525 Wh/kg and specific anode capacity 1,250 mAh/g. In… Read more »
South 8 and NanoGraf to produce batteries using liquefied gas electrolyte for the US Army
Battery tech firms South 8 Technologies and NanoGraf are collaborating to develop higher-capacity, safer and lighter batteries for the US Army. Under a $6.4-million subcontract with NanoGraf, South 8 will develop a high-rate injection system for its LiGas electrolyte to bolster domestic production of cylindrical lithium-ion batteries. Today’s soldiers lug around massive amounts of Li-ion… Read more »
GM hires EV superstar Kurt Kelty as Vice President of Batteries
It’s plain to anyone who follows the auto industry that there are pro-EV and anti-EV factions at every legacy automaker. For the last three decades, the OEMs’ interest in EVs has flapped this way and that in the winds of quarterly earnings and political shifts. Last fall, the “let’s wait awhile” contingent appeared to have… Read more »
NEO Battery Materials develops a uniform nanocoating manufacturing technique
NEO Battery Materials, a silicon anode material manufacturer, has created a nanocoating manufacturing technique with its patented NBMSiDE silicon anode materials. NEO can create uniform nanocoating layers from uniformly-coated silicon particles to improve NBMSiDE’s performance. NBMSiDE capacity retention was previously poor due to the mechanical degradation of non-uniform coatings. NEO says that this uniform nanocoating… Read more »
