Li NMR spectroscopy reveals rapid Li ion dynamics in the poor Li ion conductor Li ₆ PS ₅ I; long-range motion is, however, only possible for Li ₆ PS ₅ Br and Li ₆ PS ₅ Cl with anion site disorder.

This work reviews recent developments on Li-ion microbatteries. After a short literature overview, use of TiO₂ as an alternative anode for Li-ion batteries and enhanced electrochemical performances of nanostructured titania electrodes is introduced. Principle and formation mechanism of self-organized TiO₂ nanotubes by electrochemical anodization and electrochemical fabrication of metallic nanowires are discussed in detail. Electrochemical performance of negative electrodes for Li-ion microbatteries composed of self-organized TiO₂ nanotubes and composite TiO₂ nanotubes–oxide nanowires is presented.

Conductivity spectroscopy and ⁷ Li spin-locking NMR relaxometry reveal enhanced ion dynamics in nanocrystalline Li ₂ O ₂ prepared by high-energy ball milling.
