Lithium-air, or lithium-oxygen, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of current lithium-ion solutions. However, scientists have struggled to overcome major challenges with the technology. The batteries waste a lot of energy as heat, degrade relatively quickly, and often require extra components to pump oxygen… Read more »

Paraclete Energy says its low-cost silicon nanoparticles can at least double your current anode capacity
Silicon has a theoretical charge capacity ten times higher than typical graphite. That is why a mind-blowing number of researchers are working towards replacing more and more of the graphite used in today’s lithium-ion battery anodes with silicon. In the last issue of Charged, we discussed Tesla’s announcement that it had begun to use small… Read more »
Kevlar-based nanocomposite foils dendrites for bulletproof batteries
Those doggone dendrites are a bane of battery builders. These pesky fern-like growths can form on the surfaces of anodes during cycling, reducing battery life or even causing a catastrophic short circuit – this is how the battery fires on the Boeing 787 are thought to have started. A team of researchers from the University… 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 »
Bob Lutz joins the board of NanoSteel
NanoSteel, a privately held company that makes proprietary nano-structured steel materials, announced this week that automotive visionary Bob Lutz has been appointed to the company’s Board of Directors. Through the development of patented alloys, NanoSteel has created a new class of steel that allows automotive engineers and designers to reduce weight through the use of… Read more »
NGen invests $29.7 million in five new Canadian EV manufacturing projects
Manufacturing innovation cluster Next Generation Manufacturing Canada (NGen) is investing C$40 million ($29.7 million) in five new advanced manufacturing projects involving 10 companies under its Electric Vehicle Manufacturing Value Chain Program. One of the pairs is battery materials developer Nano One Materials and professional services company Worley Chemetics, which will receive C$2.8 million. Nano One… Read more »
Taiwan Semi introduces new automotive-qualified rectifiers
Taiwan Semiconductor, a global supplier of discrete power electronics devices, LED drivers, analog ICs and ESD protection, has introduced two new series of high-voltage rectifiers manufactured to AEC-Q101 standards and offered in automotive- and commercial-grade versions. The fast-recovery HS1Q Series has a 1,200 V, 1 A rating and the 1,600 V standard-recovery SxY Series comes… Read more »
How the transition from graphite to silicon-anode batteries will revolutionize the EV industry
Q&A with Group 14’s CEO As EV makers continue to grapple with the challenges of using traditional lithium-ion batteries, including alleviating concerns about range anxiety, safety and raw material sourcing, battery material manufacturers are exploring alternative chemistries. There has been talk about using silicon anodes to replace graphite anodes in lithium-ion batteries for several years…. Read more »
ABB exec talks microgrids, switchgear and charger-agnostic systems
A public charging or fleet charging site—or pretty much any installation larger than one or two Level 2 chargers—consists of more than just the chargers that drivers interact with. Behind the scenes, you’ll find a transformer, a cabinet full of switchgear, and increasingly, microgrid elements such as battery storage and/or PV panels. ABB makes all… Read more »
Amprius ships A-Sample EV battery cells to USABC
Amprius Technologies, which produces lithium-ion batteries with silicon anodes, has shipped its SiMaxx A-Sample EV Cells to the United States Advanced Battery Consortium (USABC). Amprius’s internal testing of the A-Sample EV cell has shown specific energy of 360 Wh/kg at the beginning of its life—surpassing the USABC program target of 275 Wh/kg at end of… Read more »
