How do tritium batteries work?

Question

I mean, how would they look like and what kind of components would would be comprised of?

Answer 1

Google it. The high energy electron emitted during the neutron particle decay of tritium, combined with >12 yr half-life means long life, low risk to body, low power output.

From Wiki:

In May 2005, a group including researchers from the University of Rochester and from the University of Toronto announced [1] [2] a small battery powered by the beta-particle-emitting decay of tritium and positioned the product as suitable for pacemakers or low-current electrical household devices. The device gathers energy from the beta-particles that pass through a silicon diode, in a manner analogous to photovoltaic cells. This technique is called betavoltaics and has the potential to radically increase atomic battery efficiency and energy production densities.
