Interpretation of ionic conductivity mechanism of some polymer with Li salt in terms of free volume

What is it about?

We relate the ionic conductivity in terms of the free volume fraction in polymer matrix with Li-salt added. To measure the free volume, we use the positron annihilation lifetime spectroscopy and to compute it, we use Simha Soncynsky hole theory. They are in the well accordance.

Why is it important?

If we understand ionic conductivity mechanism in polymers, then we construct such a polymer so that we get much appropriate material for the battery application.
