“…6 Several approaches have focused on improving the capacity retention by lowering the pulverization of SnO 2 and mechanical degradation due to volume expansion. For example, Ding et al 7 reported that a capacity of 773.7 mA h g À1 could be retained aer 100 cycles by using a nanocomposite SnO 2 -Se thin lm. Similarly, a study by Yu et al has shown that a novel composite of Li 2 O-CuO-SnO 2 exhibited a capacity of 1158 mA h g À1 at 0.5 C and 525 mA h g À1 at 8 C aer 100 cycles.…”

This paper reports the use of thin titania or alumina coatings on tin oxide nanowire arrays for high cyclability electrodes for lithium-ion batteries. We demonstrate that such coatings can significantly reduce irreversible capacity loss associated with the formation of a solid electrolyte interface and improve the capacity retention at high rates. Specifically, tin oxide nanowires grown on stainless steel substrates were conformally coated with thin films of either titania or alumina using atomic layer deposition and were tested as anodes in coin cells. Both titania and alumina coatings resulted in no initial capacity loss due to solid electrolyte interface formation in the first cycle. Tin oxide nanowire array electrodes coated with 5 nm thick titania layer and 1 nm thick alumina layer retained capacities of 767 and 725 mA h g À1 after 30 cycles using current density of 700 mA g À1 . Both electrodes retained capacity around 664 mA h g À1 after 30 cycles using a current density of 1500 mA g À1 , respectively. The results indicate that thin coatings acted as mechanical shells preserving the electrode nanostructure morphology necessary for high capacity retention. The study also showed that within the first two cycles, tin migrates out forming nanoclusters on the surface of nanowires due to both stress enhanced diffusion and the Kirkendall effect. The presence of tin nanoclusters on the surface of protective layers further enhances high rate capability.

Continuous advances in microelectronics and micro/nanoelectromechanical systems enable the use of microsized energy storage devices, namely solid-state thin-film -batteries. Different from the current button batteries, the -battery can directly be integrated on microchips forming a very compact "system on chip" since no liquid electrolyte is used in the -battery. The all-solid-state battery (ASSB) that uses solid-state electrolyte has become a research trend because of its high safety and increased capacity. The solid-state thin-film -battery belongs to the family of ASSB but in a small format. However, a lot of scientific and technical issues and challenges are to be resolved before its real application, including the ionic conductivity of the solid-state electrolyte, the electrical conductivity of the electrode, integration technologies, electrochemical-induced strain, etc. To achieve this goal, understanding the processing of thin films and fundamentals of ion transfer in the solid-state electrolytes and hence in the -batteries becomes utmost important. This review therefore focuses on solid-state ionics and provides inside of ion transportation in the solid state and effects of chemistry on electrochemical behaviors and proposes key technology for processing of the -battery.

“…A SnO 2 /Se film was also fabricated through the PLD method and the SnO 2 /Se electrode exhibited a high reversible capacity and good cycle performance. 109 TiO 2 has been widely used as the host of S to efficiently encapsulate it in Li-S batteries to improve the cycle life and capacity retention. [114][115][116] The TiO 2 used in the coating layers or shell structures could promote the interaction between TiO 2 and S, which could form an electrostatic attraction (S-Ti-O) and enhance the surface adsorption of polysulfide on the TiO 2 .…”
