3. ∗ Idea was introduced in 1950 and patented to Tracer
Lab.
∗ Radioisotope electric power system developed by Paul
Brown.
∗ Chemical batteries require frequent replacements and
are bulky.
∗ Fuel and Solar cells are expensive and requires sunlight
respectively.
INTRODUCTION

4. ∗ Uses emissions from radioactive isotope to generate
electricity.
∗ Nuclear batteries have lifespan upto decades.
∗ Do not rely on nuclear reaction , so no radioactive
wastes.
∗ Can be used in inaccessible and extreme conditions.

5. METHODOLOGY

6. ∗ Stage 1: No movement of charges due to equilibrium
state of PN-junction.
∗ Stage 2: Introduction of radioactive source.
∗ Stage 3: Colloision of beta particals.
∗ Stage 4: Creation of Fermi potential.
∗ Stage 5:Movement of electrons from electrode A to
RL load.
∗ Stage 6: Returning of electrons to ground state.

8. ∗ Life span- minimum of 10 years.
∗ Reliable electricity.
∗ Lighter with high energy density.
∗ It is efficient.
∗ Fuel used is the nuclear waste from nuclear fission.
MERITS

9. ∗ High initial cost of production.
∗ Energy conversion methodologies are not much
advanced.
∗ Regional and country-specific laws regarding use
and disposal of radioactive fuels.
∗ To gain social acceptance.

10. ∗ Space application
∗ Medical application
∗ In Mobile devices.
∗ It can be used in Automobiles
APPLiCAtiONs

11. ∗ Small compact devices of future, requires small
batteries.
∗ Nuclear batteries increase functionality, reliability and
longevity.
∗ Until final disposal all Radiation Protection Standards
must be met.
∗ Batteries of the near future.
