How to store the energy produced by piezoelectric generator

[suryaprakash]

My project is about to store the electrical energy produced by the gas stove lighter.
I search and found that the gas lighter may produce 800 volt and 0 current.
So now I need to know how to increase this current and store into the battery.

Plz give me some idea...
