Battrion is a Swiss spin-off of ETH Zurich and works closely with the Laboratory for Nanoelectronics at ETH. Battrion develops and markets innovative fabrication technologies for lithium ion batteries aimed at increasing the charging speed of high energy density cells. By innovating on a single step more
At Battronics, we summarize the knowledge, create reports and give detailed seminars about different technologies used in Li-ion batteries. These range from different cathode chemistries up to aging analysis for applications in e.g. electric vehicles. more
Curtin University researchers have unexpectedly discovered a new way to make crystalline graphite, an essential material used in the making of lithium ion batteries. Described in a research paper published in Nature's Communications Materials, the new technique does not require the typical metal cat more
Lithium-ion batteries contain salts rich in fluorine, which decompose in humid air to toxic, highly corrosive hydrogen fluoride. The hazardous nature of this substance makes recycling more difficult and more expensive. A research project entitled "Fluoribat" is now being launched at Empa to solve th more
Cell phone batteries often heat up and, at times, can burst into flames. In most cases, the culprit behind such incidents can be traced back to lithium batteries. Despite providing long-lasting electric currents that can keep devices powered up, lithium batteries can internally short circuit, heatin more
What happens when lithium-ion batteries overheat and explode has been imaged inside and out for the first time by a team led by UCL PhD student Donal Finegan (UCL Chemical Engineering) and Dr Paul Shearing (UCL Chemical Engineering).Understanding how Li-ion batteries fail and potentially cause a ... more
The new iPhone is slimmer and faster than ever. But like most new generations of smartphones, its battery has pretty much stayed the same over the years. Short of carrying an external battery all the time, is there any way to extend the life of your smartphone battery? In the latest Reactions ep ... more
Researchers at the University of California, Riverside's Bourns College of Engineering are using waste glass bottles and a low-cost chemical process to create nanosilicon anodes for lithium-ion batteries that will extend the battery life of electric vehicles and personal electronics. more
Lithium Ion is becoming the technology choice for HEV, PHEV, as well as many stationary applications. With such large battery packs it is important to understand how the individual cells and packs will behave in a variety of scenarios. One of the mai more
Lithium ion battery technology offers many advantages in portable power application but one major concern is safety – thermal runaway of the device in both normal and abusive situations. In the following article, it will be shown that by means of adi more
In this month’s Periodic Graphics in C&EN, we’re looking at the chemistry behind the recent news stories of lithium-ion batteries in some devices catching fire. You can see the full graphic over on the C&EN site. Also, for more lithium battery chemistry, head over to the recent RealTimeChem Week gra more
Today’s graphic takes a look at the research of Kent Griffith (@kentjgriffith), a PhD student from the University of Cambridge who’s currently looking into developing advanced lithium ion batteries to power our phones, laptops, and more. more
As we head into 2018, it’s time to take a look back at some of the biggest science news stories over the past year. This year’s science news featured poisonous frogs, battery fires, element creation, and more! more
A recent discovery of anionic redox activity in Li-rich layered compounds opens a new direction for the design of high-capacity cathode materials for lithium-ion batteries. Here using extensive ab initio calculations, the thermodynamic existence of the Li-rich phase in LiFePO4 to form Li1+xFe1-xPO4 more
By controlling the morphology and particle size of the epsilon polymorph of vanadyl phosphate, ε-VOPO4, it can fully reversibly intercalate two Li-ions and reach the theoretical capacity of 305 mA h g−1 over two voltage plateaus at about 4.0 and 2.5 V. more
