No, by design, you have as close as possible to raw metal on one of the electrodes when battery is fully charged. That's the chemistry behind it - its moving metal between oxidation states. When it burns down, it also moves to higher oxidation states. Volatility is baked in. Usually you have lithium in carbon matrix that acts as physical sponge. But that's just raw lithium in a sponge. It will still burn like hell.
