Popis:	Fabrications of micro-dot electrodes of LiCoO 2 and Li 4 Ti 5 O 12 on Au substrates were demonstrated using a sol–gel process combined with a micro-injection technology. A typical size of prepared dots was about 100 μm in diameter, and the dot population on the substrate was 2400 dots cm −2 . The prepared LiCoO 2 and Li 4 Ti 5 O 12 micro-dot electrodes were characterized with scanning electron microscopy, X-ray diffraction, micro-Raman spectroscopy, and cyclic voltammetry. The prepared LiCoO 2 and Li 4 Ti 5 O 12 micro-dot electrodes were evaluated in an organic electrolyte as cathode and anode for lithium micro-battery, respectively. The LiCoO 2 micro-dot electrode exhibited reversible electrochemical behavior in a potential range from 3.8 to 4.2 V versus Li/Li + , and the Li 4 Ti 5 O 12 micro-dot electrode showed sharp redox peaks at 1.5 V.
