Betavoltaics were invented in the 1970s. Some pacemakers in the 1970s used betavoltaics based on promethium, but were phased out as cheaper lithium batteries were developed. Early semiconducting materials weren''t efficient at converting electrons from beta decay into usable current, so higher energy, more expensive—and potentially hazardous—isotopes were used. The more efficient semiconducting materials used as of 2019 can be paired with relatively benign isot
What materials are used in solid-state batteries? Key materials in SSBs include solid electrolytes (ceramics, polymers, composites), anodes (lithium metal, graphite), and
In 1959, global CO 2 levels were at 313 parts per million (ppm). Now, just six decades later, they are 100 ppm higher, recently surpassing 412 ppm in September of 2019 .This is an unprecedented change in atmospheric conditions, which effect is already having, and will increasingly have a major impact on the Earth in the decades to come .
NanoTritium batteries have been employed for various applications where accessibility is limited and long-term power is beneficial, including powering components on COMSEC devices, satellites, unattended sensors, and implantable medical devices. Despite containing radioactive materials, the batteries are considered safe for implants due to their engineering and inherently low radiation levels, which prevent an individual from receiving a dose higher than the set 15 rem whole body li
The raw materials used to make semiconductors are essential for manufacturing computer chips. Although most people do not give it much thought, these raw materials power everything from medical devices to gaming
The advantages of large storage capacity, higher concentration and safer storage of tritium make metal tritide batteries superior to gaseous tritium batteries. This paper
To make a tritium battery with p–n junction device and solid tritium source, the conditions and method to manufacture titanium hydride was developed. The activation was performed at 500 °C and film was harder than powder to hydrogenate. Maximum atomic ratios of ∼1.3 and ∼1.7 were obtained for powders and films, respectively. Further optimization is
Tritium production begins with lithium, a soft metal often used in batteries. Specifically, it requires a type of lithium called lithium-6, which reacts easily with neutrons. The Nuclear Reaction In a nuclear reactor, lithium-6 is bombarded with neutrons. This causes a reaction that splits the lithium into tritium and helium. Think of it like breaking apart a puzzle piece to create something
The low amounts of energy released as tritium decays allow for unique use cases, making it perfect for powering low-power devices and microelectronics through specially
Nuclear batteries, like City Labs'' NanoTritium™ technology, use radioactive decay from isotopes like tritium to generate steady electricity for decades. These batteries are ideal for low-energy devices in extreme environments where
Tritium is a beta- (electron) emitting byproduct of certain nuclear power plants (e.g., CANDU Reactors), which City Labs implements in a safe and effective power-harvesting
Biphasic ceramic pebbles, consisting of Li4SiO4 and Li2TiO3, are being developed as the EU reference tritium breeding material for ITER and DEMO. A modified melt
Tritium has a half life of 12.32 years, meaning only half of the battery''s fuel will be used after more than a decade. The tritium battery will continue emitting low powered electrons independently of temperature or any environmental conditions. This is very different from conventional batteries that are dependent on chemical reactions to
NanoTritium batteries employ principles of betavoltaic conversion and radioactive beta decay rather than conventional electrochemical cells to generate power, harnessing electrons released as the contained tritium naturally decays into helium-3, a non-radioactive isotope. Current models are capable of producing an output voltage of 0.8 to 1.1 V with a current density of 150
Understanding the key raw materials used in battery production, their sources, and the challenges facing the supply chain is crucial for stakeholders across various industries.

Step 1 - Gather Materials. Grab ten 2x12mm tritium gas tubes, the contents of your kit, the various tools we talked about earlier, and a breadboard (optional). And don''t forget about the soft cloth! It''s not a bad idea to polish the PV cells and maybe your tritium vials just to remove any smudges or dust that could effect the efficiency of the
For a tritium battery, we use a similar semiconductor, but we use the beta radiation emitted from tritium instead of sunlight to serve as the energy source.” While the energy emitted from tritium is modest – we''re talking about microwatts – it does have its advantages. Compared to a solar cell, which only produces energy during the daytime, the radiation emitted
"Diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power," said Sarah Clark, director of Tritium Fuel Cycle at UKAEA. The batteries created by the U.K. scientists leverage the radioactive decay of carbon-14, an isotope with a half-life of 5,700 years and are best known for its use in radiocarbon dating to generate
Betavoltaics are a type of nuclear battery that do not rely on temperature differences between nodes to generate a charge. Our tritium betavoltaic battery converts the incident energy of decaying beta particles into electricity. Radioactive decay is a natural process that does not require artificial chemical reactions.
Natural tritium production occurs when cosmic rays interact with atmospheric gasses, creating tritium atoms. How artificial tritium is made is different, and instead involves irradiating lithium-6 with neutrons in a nuclear reactor—a process that converts some of the lithium-6 into tritium.
Technology What Is Tritium? Tritium is a radioactive isotope of hydrogen, meaning it spontaneously and consistently emits radiation. It is distinguished by the presence of two neutrons and one proton in its nucleus, in contrast to the single proton with no accompanying neutrons found in ordinary hydrogen.
Tritium is the most benign radioactive isotope and is already used as an illumination source for exit signs commonly found in schools, theaters, commercial buildings, and commercial aircraft. Tritium has a half life of 12.32 years, meaning only half of the battery's fuel will be used after more than a decade.
Lithium Metal: Known for its high energy density, but it's essential to manage dendrite formation. Graphite: Used in many traditional batteries, it can also work well in some solid-state designs. The choice of cathode materials influences battery capacity and stability.
NanoTritium batteries are ultra-low-power, long-life betavoltaic devices developed by City Labs, Inc. These nanowatt-to-microwatt batteries utilize the natural decay of tritium, a radioactive isotope of hydrogen, to generate continuous power for over 20 years.
