Technique applied to measure the chemical diffusion coefficient of the intercalating species within insertion-host electrode materials with the help of an electrochemical cell, followed by the current response on the staircase potential signal that is recorded as currenttime curve [i]. The theory of this technique is based on... 

There are two main kinds of rechargeable battery based on lithium chemistry the lithium-metal and the lithium-ion battery. In both the positive electrode is a lithium insertion material the negative in the former is lithium metal and in the latter it is a lithium insertion host. The reason for the application in lithium batteries of insertion electrode materials, which are electronic and ionic conductive solid matrixes (inorganic and carbon-based), is that electrochemical insertion reactions are intrinsically simple and highly reversible.

Anatase Ti02 is generally considered to be the most electroactive Li insertion host among all Ti02 polymorphs. Many efforts were made to investigate anatase Ti02 for Li storage. The Li insertion and... 

Ti02(B) NWs attract more research interest since they show superior electrochemical performance as a Li+ insertion host than their bulk counterpart (Fig. 5.16). Ti02(B) NWs were prepared via a simple hydrothermal reaction. They could accommodate 0.91 Li to form Lio.9iTi02 (305 mAh/g) at 10 mA/g and show excellent rate performance, the intercalation capacities are around 200,155,125, 100 and 85 mAh/g at the rate of 200, 500, 1000, 2000 and 3000 mA/g. XRD patterns for Ti02(B) NWs at various states of charge shows no obvious expansion of lattice after Li-ion insertion. ...

The intercalation compound should allow for insertion/extraction of a large number of lithium ions per formula unit to maximize cell capacity. This depends on the number of available lithium sites and the accessibility of multiple valence states for M in the insertion host...
