A thin film silicon anode for Li-ion batteries having a very large specific capacity and long cycle life. J. Power Sources 136, 303–306 (2004). Ng, S.-H. et al. Highly Reversible Lithium Storage in Spheroidal Carbon-Coated Silicon Nanocomposites as Anodes for Lithium-Ion Batteries. Angew.
Power and energy density determined from constant current discharge measurements for thin-film batteries with a Li anode and the indicated thin-film cathode: c LiCoO 2 (□), c LiMn 2 O 4 (▵), and n Li x Mn 2−y O 4 (○). The cathode thickness is given in μm.
Thin-film batteries are an efficient means of storing the intermittently produced electricity from solar and other renewable energy sources. It is possible to design these batteries with a negligible self-discharge rate, allowing them to be stored for extended periods without suffering a serious loss of energy capacity .
1. Introduction Thin-film rechargeable lithium batteries developed at Oak Ridge National Laboratory (ORNL) are fabricated by physical vapor phase deposition processes , , , .
Finally crystalline silicon and thin-film PV solar cells technologies were compared together from the perspective of “total factors”, “technical factors”, “economic factors” and “payback period factor”.
But in the state where in “payback period factor” has been considered as performance factor, the mean of efficiency score for Thin-film is higher than the mean of efficiency score for crystalline Silicon. After hydro and wind powers, photovoltaic (PV) is the third renewable energy source from the perspective of globally capacity.
