Unveiled in January 2024, it is allegedly generating 100 microwatts of power and a voltage of 3V and has a lifetime of 50 years without any need for charging or maintenance. [14] Betavolt claims it to be the first such miniaturised device ever developed. [14]
The Chinese startup Betavolt claimed in January 2024 to have a miniature device in the pilot testing stage. [13] It is allegedly generating 100 microwatts of power and a voltage of 3V and has a lifetime of 50 years without any need for charging or maintenance. [13] Betavolt claims it to be the first such miniaturised device ever developed. [13]
Betacel is considered to be the first commercially successful betavoltaic battery. [1] [2] [3] It was developed in the early 1970s by Larry C. Olsen at the American corporation McDonnell Douglas, using the radioisotope Promethium-147 as the beta-electron source coupled to silicon semiconductor cells.

This battery is proposed to run on the radioactivity of waste graphite blocks (previously used as neutron moderator material in graphite-moderated reactors) and would generate small amounts of electricity for thousands of years. The battery is a betavoltaic cell using carbon-14 (14 C) in the form of diamond-like carbon (DLC) as the beta ...
EV adoption will surge—take it from someone leading a battery tech startup after 17 years at GM. ... investing $75 million in us earlier this year. I’ve worked for Fortune 50 companies and am ...
Modern batteries aren't hampered so much by their capacity as their long-term lifespan -- a lithium-ion pack can easily become useless after a few years of heavy use. That's bad enough for your ...
The plutonium-238 used in these RTGs has a half-life of 87.74 years, in contrast to the 24,110 year half-life of plutonium-239 used in nuclear weapons and reactors. A consequence of the shorter half-life is that plutonium-238 is about 275 times more radioactive than plutonium-239 (i.e. 17.3 curies (640 GBq )/ g compared to 0.063 curies (2.3 GBq ...
