Abstract
The present invention generally relates to electrochemical devices, such as electrochromic (EC) devices and thin film batteries (TFB), and in particular to anodes of electrochemical devices with improved intercalation and/or transport properties. Some embodiments of the invention include anodes, such as nickel oxide, doped with Si, Sn, SiOand/or SnO, which may be in the form of nanoparticles or even substituted atoms/molecules. These nanoparticles/substituted atoms, which have higher lithium intercalation capability, distort the lattice of the anode, improving movement and intercalation of Li ions. In some other embodiments, the anode may be formed of silicon oxide and/or tin oxide, which materials have good transport and intercalation of Li ions.
