In this proceeding I briefly discuss the possibility of relic decaying or annihilating particles to explain the cosmological 7Li anomaly and/or to be the source of significant amounts of pre-galactic 6Li. The effect of relic massive charged particles through catalysis of nuclear reactions is also discussed. The possibility of a connection of the 7Li problem to the cosmic dark matter and physics beyond the standard model of particle physics, such as supersymmetry, is noted.
