Comparing Nuclear Batteries with Traditional Batteries

Like Betavolt's BV100, nuclear batteries differ significantly from traditional batteries in their working mechanism, cost, lifespan, and applications. Conventional batteries generate power through electrochemical reactions, whereas nuclear batteries, including atomic and betavoltaic types, generate electricity from the decay of radioactive particles. 

Nuclear batteries can be thermal, converting heat from radioactive decay into electricity, or non-thermal, directly converting energy released during decay into an electric current. They are known for their high energy density and long service life, offering continuous power for decades. This makes them particularly suitable for applications where long-term, low-maintenance power is needed, like in space missions or remote sensing equipment. 

However, nuclear batteries are more expensive than traditional batteries and challenge public perception due to their use of radioactive materials. Despite these challenges, advancements in this field, particularly in using safer isotopes like tritium, are making these batteries more accessible and potentially less costly with broader adoption.
