Li-ion batteries: news, progress, history and background

This is insane! As a long term peer reviewer I read all articles (not only under review) very carefully. From relatively wide observation the only half of the submitted papers might be accepted for further publication. Not counting in this half the articles which need some (more or less) modifications. Indeed, there are almost half of the articles which went through my hands have a very low quality. These include repeating/copying someone else's research, very poor understanding of the obtained results, not willingness, even to try to explain the obtained results, but just referring to previously published articles (from other researchers)  (which means their result is not unique). Since I do not connect with the publishers other than by e-mail as a reviewer or author, I do not know how busy are Journals is to feel the issues. However, I understand that the publishers have to earn some money from what they are doing. Good it or not (very much) for the progress is a big question

Article on Business Insider : Tesla Stock Is Tanking After A Third Model S In Two Months Catches Fire ( Mamta Badkar Nov. 7, 2013) A Tesla Model S car caught fire on Wednesday in Smyrna, Tennessee, according to Tesla Motors Club blog (via ValueWalk). This is the third Tesla to Model S vehicle to catch fire in the past six weeks, a Tesla spokesperson confirmed to Reuters. The driver of the vehicle was said to have sustained no injuries and a Tesla team is on its way to Tennessee to see what happened. Tesla again pointed out that the fire was the result of an accident and not  "spontaneous." @Nashvillian_ on Twitter posted this image : I-24 #tesla #teslafire pic.twitter.com/ia9tbftn4V — E (@NASHVILLAIN_) November 6, 2013 A Tesla Model S caught fire in Mexico back in October after the car crashed through a concrete wall and into a tree. Before that, another Model S caught fire after colliding with a large me

Unlike dense ceramic coatings applied as a separate layer on competing separators, PPT’s products contain ceramic particles that are thoroughly distributed throughout their chemically inert PVDF polymer. The particles reside primarily in the pore walls, leaving a large and uniform open pore structure that enables ions to pass through with less resistance and less heat generation.  * More power in high-current applications  * Reduced separator shrinkage  * Increased thermal stability with less cell degradation  * Extended cycle life * Higher bake-out and operating temperatures  * Improved puncture and abuse resistance    Although, the application of such separator may improve safety, however according to presented test data it will have minimal effect, or not significant. Depends on battery package, it may have serious explosion (due to electrolyte flammability) at much lower temperature.  

Polypore’s Celgard Files Suit Against Sumitomo Over Batteries - Bloomberg : "" The complaint, filed Feb. 22 in federal court in Charlotte, North Carolina, claims Sumitomo is infringing a patent issued in 2002 for a separator in high-energy rechargeable batteries. The separators prevent short circuits that can reduce efficiency and limit safety problems from overheating. (Via Bloomberg .)

Power bank battery dismantled and reviewed (backup battery for iPho ne produced in China) Before we start some explanation and disclaimer . Here is a short review, based on observations and simple calculation of one of "power bank" or backup battery for iPhone , which may be found in any shop. I did not intend to do this review simply because I did not buy that device and not going to buy such things in a future (ne ar future ). This example device I have got from my frie nd after its stoped working and actu ally the pla s tic shel l become opened (Fig. 2) . This is not a denunciation or exposure for certain product or certain manufacturer or certain country. I hope t his review will make you more skeptical and realistic about what you see and what you get. All dismantle and photos, as well calculation and conclusions done by me.   Although I dismantle Li -ion batteries (LIB) of any shape and size many times for many years since I have work with it for the l

Teijin CNF Korea begins production of LIELSORT separators for Li-ion batteries : Teijin CNF Korea Co., Ltd., an Asan-based joint venture between Teijin and major Korean film processor CNF, has begun commercial production of LIELSORT, a Teijin-developed separator for lithium ion secondary batteries (LIBs). Of the two types of LIELSORT-branded separators, Teijin CNF Korea will initially produce one type coated with a fluorine-based compound that achieves superior adhesion to the polymer electrolyte and is highly resistant to oxidation, resulting in LIBs that offer higher output while maintaining stable high voltage. The company also plans to soon begin producing the second type, a highly heat-resistant separator coated with Teijinconex meta-aramid. As part of market expansion strategies for LIELSORT, Teijin has established a wholly owned subsidiary in Seoul called Teijin Electronics Korea Co., Ltd. to sell both separators. This production and sales network, which has close connecti

Lithium's Prospects - Seeking Alpha : As gas prices reach a staggering $4 per gallon, with early predictions in the $5 range for summer, many consumers who have been reluctant might now be considering the electric alternatives to keep their wheels turning. Lithium-ion batteries, the technology in hybrid electric cars and consumer electronics, are just one part of the lithium market but could be where the most growth and potential lie. Lithium is used in a wide range of applications, from nuclear weapons to medicine. As of 2010, the most common use for lithium was as flux for glass and ceramics (29% of lithium usage in the USA), with the battery industry trailing closely (27%). The most notable use of lithium-ion batteries is in purely electric and hybrid electric vehicles, but lithium also powers cell-phones, iPods, iPads, laptop computers, and other consumer electronics. Some of its other uses can be seen in high-heat lubricating greases, air purification, certain optical devices

Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe : Panasonic Corporation will begin mass- production this month of a compact, secure and long-life lithium-ion battery system the company has developed for European homes. This marks the first time for the company to produce in volume such a system designed for Europe. The lithium-ion battery system consists of the Panasonic battery module with nominal capacity of 1.35 kWh and a battery management system designed to control charge and discharge of the battery in accordance with customer needs. The battery system stores excess energy generated from the photovoltaic (PV) power system during peak hours of PV generation and discharges the energy as needed, providing a solution as a household battery storage system that helps self-consumption of solar-generated power. It will also enable households to reduce the dependence on grid power and facilitate the further spread of green ener
