Lipo Bag Testing Hey guys I recently decided to do some testing/experimenting with the lipo charge bags that a lot of us use. I did this for a few reasons. 1. I was bored with all the bad weather and lack of flying 2. I recently obtained an airplane trailer and had moved my charging into the trailer and was getting worried about charging in a trailer next to all my planes that are also stored in the trailer. I have lined most of my trailer with an all weather carpet that allows me to use Velcro straps which is nice but I was worried about the carpet being a fire hazard so I had started charging in lipo bags hoping that made things safer. You can see the video I made below but I learned a few things with the experiments 1. undamaged lipo batteries are really pretty hard to ignite under normal charging conditions. Most of today’s smart chargers really prevent a lot of dangerous charging errors. Even with the ridiculous things I was doing to ignite the batteries I still found it difficult to ignite them. Even when I was shorting the batteries I had to use large gauge wire or the wires would simply melt and break the connection. 2. I found a couple of different types of lipo failures. Relatively fireless explosions(rapid venting) which the lipo bag handled very well and the classic fireball/lipo fire which the lipo bag really didn’t handle that well. 3. higher voltages seemed more dangerous. In order to get impressive fire/explosions I had the best luck wiring batteries in series. So the bottom line for me is that although fire from charging a healthy , undamaged lipo battery is low you should definitely charge in a fireproof setting and don’t let the use of lipo bag allow you to be lax about where you charge. Hope you guys find this info useful and yes I realize this was a dangerous experiment and I would not recommend you guys try to repeat this experiment as I was probably lucky I didn’t get injured. kt+ More details

Novel materials design has become a critical capability to address several urgent societal problems. The Materials Genome Project, originally started at MIT (www.materialsproject.com), has as its objective to use high-throughput first principles computations on an unparalleled scale to provide basic materials property data on all known and many potential new inorganic compounds, thereby accelerating the search for new materials. Professor Ceder will show successful examples of high-throughput calculations in the field of lithium batteries, and show several new materials that have been discovered. He will discuss the public release version of the Materials Genome project, which is making large quantities of computed data freely available to the materials community. Gerbrand Ceder is a Professor of Materials Science & Engineering at MIT. He received an engineering degree from the University of Leuven, Belgium, and a Ph.D. in Materials Science from the University of California at Berkeley in 1991. Dr. Ceder’s research interests lie in the design of novel materials for energy generation and storage, including battery materials, thermoelectrics, photovoltaics, and photocatalysts. He has worked for 18 years in the Li-battery field, optimizing several new electrodes materials and has regularly served as scientific advisor to companies and investors in this area. He has published over 300 scientific papers, and holds several U.S. patents. He has served on MIT’s Energy Council as well as on several Department of Energy committees, including the workgroup preparing the Basic Needs for Electrical Energy Storage report. He has received the MRS Gold Medal, the Battery Research Award from the Electrochemical Society for his work on understanding battery materials, the Career Award from the National Science Foundation, and the Robert Lansing Hardy Award from The Metals, Minerals and Materials Society. He is a co-founder of Computational Modeling Consultants, Pellion Technologies, and The Materials Project. Dr. Ceder’s work on high-throughput computing was the inspiration of the Presidential Materials Genome Initiative.+ More details
