1.Mix the electrode material with a conductive binder to form a slurry 2.Slurry is spread on the foil 3.Thickness of electrode coating is adjusted 4.Coated foils are slit into narrow strips suitable for different sizes of electrodes Companies: A123 systems Samsung Sony Panasonic

Li – Ion Batteries for PV system High safety standards Maintenance Free Larger Calendar life Power Density: 270 W/kg Energy Density: 180 Wh/kg Compact So, energy storage comes as a package with battery packs and Battery management system Maik Neumann et al have proposed methods to calculate the Return on Investment (ROI) for PV systems installation with Li-ion battery. Taking into consideration the rising energy demand in Germany and assuming the reduction of energy storage prices, they predict for a PV system installed in 2015 on a household with consumption of 4500 kWh/year, the ROI would be positive by 2018, [2] Pic Credit: Comparison the economic analysis of the battery betweenclithium-ion and lead-acid in PV stand-alone application Suratsawadee Anuphappharadorn, Sukruedee Sukchai, Chatchai Sirisamphanwong and Nipon Ketjoy F*
