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...

Ceramic-filled Separators from Porous Power

Image
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.
