Lithium-Sulfur Batteries Overcome Another Limitation: High Temperatures

InterNano Industry News - July 26, 2016 - 3:45am
<?xml version="1.0" encoding="UTF-8"?> Could safe, durable and high-temperature Li-S batteries lead to EV applications? Image: iStockphoto Lithium-sulfur (Li-S) batteries have been pursued as an alternative to lithium-ion (Li-ion) batteries for powering electric vehicles due to their ability to hold up to four times as much energy per unit mass as Li-ion. However, Li-S batteries don’t come without some problems. For instance, the sulfur in the electrode can become depleted after just a few charge-discharge cycles, or polysulfides can pass through the cathode and foul the electrolyte. Another issue Li-S batteries face is the difficulty of ensuring that they operate safely at high temperatures due to their low boiling and flash temperatures. Now, researchers at the University of Western Ontario, in collaboration with a team from the Canadian Light Source, have leveraged a relatively new coating technique dubbed molecular layer deposition (MLD) that promises to lead to safe and durable high-temperature Li-S batteries. This MLD technique is essentially an adaptation of the conventional atomic layer deposition (ALD) techniques that have been used to deposit thin inorganic oxide films. Where MLD departs from its predecessor is that it can incorporate organic components into the films, making it possible to create hybrid organic-inorganic thin films. MLD is a technique that has proven itself applicable for use in energy storage systems; it provides a high level of control over film thickness and the chemical composition of the target material at a molecular scale. In research described in the journal Nano Letters , the Canadian researchers were able to fabricate safe, high-temperature Li–S batteries on universal carbon–sulfur electrodes using an MLD alucone coating “We demonstrated that MLD alucone coating offers a safe and versatile approach toward lithium-sulfur batteries at elevated temperature,” said Andy Xueliang Sun, who led the research at the University of Western Ontario, in a press release. In the experiments, the researchers demonstrated that the MLD alucone coated carbon-sulfur electrodes remained stable and even showed improved performance at temperatures as high as 55 degrees Celsius. The researchers expect that these performance figures should significantly prolong battery life for high-temperature Li-S batteries.

“Polymeric Nanocapsules as tools to face challenges in Regenerative Medicine

InterNano - Upcoming Events - July 25, 2016 - 12:31pm
WebinarTuesday, August 23, 2016 - 10:00am http://amires.eu/free-webinar-polymeric-nanocapsules-as-tools-to-face-challenges-in-regenerative-medicine/ You are cordially invited to take part in a FREE of charge webinar focused on “Polymeric Nanocapsules as tools to face challenges in Regenerative Medicine” to be held on 23rd August 2016, from 15:00 to 16:00 CET by Dr. Gemma Vilar from LEITAT Technological Center. This is a first webinar of a series an aim of which is to improve know how exchange, identification of key European experts and a wider networking among European Technology Platform on Nanomedicine (ETPN) members (e.g. for collaborative projects). It is intended to keep webinars open for ETPN non-members, particularly for industrial companies, to facilitate cooperation between researchers and enterprises (mainly SMEs). The webinar will be organised by a teleconferencing tool CISCO WebEx, free to all registered participants (login details will be send only to registered participants). To register and request your login, please send your full name, affiliation, organisation and email to: frycek@amires.eu
