Ceramic-filled Separators from Porous Power

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.

Panasonic to begin mass-production of long-life Li-ion battery system for solar-powered homes in Europe

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

Short notes on Open Access, Peer review & (insane) publications

Image
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
