About 10% volume expansion upon
Li intercalaion
Theoretical maximum capacity is
372mAl/g(LiC6)
Coating by Conductive Materials
The major effects and advantages
No classical binder is required to prepare mechanically and electrochemically stable anodes.
Irreversible capacity in the first cycle
2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics
② C-V chara
of the material such as glass.
For many of Materials, if we drop water, it makes waterdrop. However, for the material which coated TiO2, after it contacts with ultraviolet, the drop of the water doesn't make waterdrop; it just spread out. At the material which is coated with Titanium dioxide, the dirtiness is easily cleared and the water drop doesn't appear after contact with the water.
Coat [koʊt] :A coat is a piece of clothing with long sleeves which you wear over your other clothes when you go outside
Germanic languages ‘kozzo’, ‘cote, cotte’ →’coat’
duffel coat, greatcoat, housecoat, overcoat,
