Chinese Company Announces Mass Production of Small Nuclear Battery With 50-Year Lifespan (tomshardware.com) 172

"Chinese company Betavolt has announced an atomic energy battery for consumers with a touted 50-year lifespan," reports Tom's Hardware: The Betavolt BV100 will be the first product to launch using the firm's new atomic battery technology, constructed using a nickel -63 isotope and diamond semiconductor material. Betavolt says that its nuclear battery will target aerospace, AI devices, medical, MEMS systems, intelligent sensors, small drones, and robots — and may eventually mean manufacturers can sell smartphones that never need charging...

[T]he BV100, which is in the pilot stage ahead of mass production, doesn't offer a lot of power. This 15 x 15 x 5mm battery delivers 100 microwatts at 3 volts. It is mentioned that multiple BV100 batteries can be used together in series or parallel depending on device requirements. Betavolt also asserts that it has plans to launch a 1-watt version of its atomic battery in 2025. The new BV100 is claimed to be a disruptive product on two counts. Firstly, a safe miniature atomic battery with 50 years of maintenance-free stamina is a breakthrough. Secondly, Betavolt claims it is the only company in the world with the technology to dope large-size diamond semiconductor materials, as used by the BV100. It is using its 4th Gen diamond semiconductor material here...

[T]he Betavolt BV100 is claimed to be safe for consumers and won't leak radiation even if subjected to gunshots or puncture... Betavolt's battery uses a nickel -63 isotope as the energy source, which decays to a stable isotope of copper. This, plus the diamond semiconductor material, helps the BV100 operate stably in environments ranging from -60 to 120 degrees Celsius, according to the firm...

Betavolt will be well aware of devices with a greater thirst for power and teases that it is investigating isotopes such as strontium- 90, promethium- 147, and deuterium to develop atomic energy batteries with higher power levels and even longer service lives — up to 230 years.

    But "smartphones"? That is just a marketing lie. Also note prices are mentioned nowhere. This is likely for sensors in expensive, hard to reach places and the like. May also be for implanted medical devices.

        • Ah, I see. But these are thermoelectric, based on alpha-decay. The natural decay alpha particles are entirely stopped by a very thin shield, I was commenting on the beta decay type, which were similar to the "new" Chinese tech; some betas would fly through shielding that will block all alphas, and I expect you don't want too big a battery in your chest.

        Pacemakers with RTGs were used worldwide (e.g. made in the US by Cordis, Medtronic and Coratomic). Exposure to the patient from gamma emissions that passed through the titanium case was estimated to be about 100 millirems per year. They fell out of favour following improvements in lithium battery technology.

        The device described in the article is not an RTG. An RTG works by converting decay heat to electricity with thermocouples or other solid state devices, and is inherently quite inefficient. This company is claiming to have developed a consumer-ready betavoltaic device.

        A betavoltaic device captures emitted beta particles (i.e. high-energy electrons) directly to generate electrical power. This is far more efficient than an RTG, so your source doesn't need to be anywhere near as radioactive for the same power output as an RTG (you can use less source material, or source material with a longer half life). An added benefit is that it produces far less waste heat for the same power output as an RTG.

        There have been rumours floating around for years that intelligence agencies have developed betavoltaic devices for powering spy satellites. However this seems to be the first time someone's claimed to have a betavoltaic device this small, cheap and robust.

        Clearly a concern which needs addressing so I looked it up. The beta particles emitted by nickel-63 are relatively low energy and travel about 0.1 mm in tissue. I expect there's enough shielding on the battery that virtually none actually escape. If nothing else, you want to capture as many as possible to make the battery more efficient.

      At least this company is being a little more realistic with their claims, but it sounds like their big breakthrough is to make the current tech either cheaper or in more volume then their competitors.

      You might be surprised how desirable this would be to a lot of industrial users. As an example, big infrastructure systems like water, roads, and bridges, benefit hugely from extended battery life for sensors.

      Lots of buildings have a sub 50 year lifetime. You could embed sensors in them during construction, never to be replaced.

      Small nuclear batteries are great for long term energy, but they produce so little power. The most practical use for them is in places you will NEVER be able to replace the battery, like in space probes, where energy demands are low and heat isn't too big of a problem. (or in some cases, a useful by-product) TEGs are just so ridiculously inefficient, and there really hasn't been any breakthroughs in TEG design in decades.

      Efficiently is totally irrelevant for devices like this. It is not about energy storage. It is about getting a long-term energy supply in places where you cannot get it any other way or only even more expensive ways.

      • The output of the 100 microwatt battery for 50 years is less than a 100 watt bulb for 1/2 hour. I imagine it has an efficiency of less than 0.1% and is still cheaper than changing the battery once on sufficiently inaccessible equipment.

          The efficiency of converting the electron energy into electrical power isn't that bad, although still low compared to other power systems. But efficiency per se isn't the point; the objective is a small long-lived power source with no moving parts.

          Diamond's a good semiconductor for this; at low electron fluences you want the largest bandgap you can get. Back when I did the review, diamond semiconductor technology wasn't there yet.

          There are companies in the US working on betavoltaics and also companies (and universities) working on diamond semiconductors, but this is the first I've seen this tech ready to market..

Heck, just strain gauges with sensors embedded in concrete might be something that prevents a building collapse.

        Just to get the terminology right:
        --Thermoelectric conversion converts heat energy from a radioisotope source into electricity using thermoelectric conversion (Seebeck effect). These are no moving parts converters.
        --Stirling engines are an example of dynamic conversion, turning heat energy into motion using a heat engine. The motion (e.g., a piston for Stirling-cycle engines, a rotor for Brayton-cycle) is then turned into electricity with a generator.
        -- Alpha- and beta-voltaic devices turn the charged particle emission of an isotope into electrical power using the energy of the particle to create electron-hole pairs in a semiconductor, without the intermediate step of turning the radioactive decay into heat first. This is essentially the same operational principle as a solar cell, but with charged particles instead of photons. They are also no-moving parts devices.
        --Thermionic energy conversion does a similar thing with a vacuum diode instead of a semiconductor.
        --Optoelectric nuclear conversion is an old-fashioned word for an alpha- or beta-voltaic conversion that uses an intermediate phosphor to convert the charged-particle radiation from a radioisotope source into light, which is then converted into electricity by a photovoltaic cell.

        There are a few other conversion technologies to turn radioisotope decay into electricity (I'm a great advocate of thermoradiative technology), but those are the main ones.

          Technically at some point there will be less than 1 atom of radioactive material at which point it is 'dead'. Zeno only works in your head, not reality. Even then, technically the whole mass could spontaneously decay instantly; half-life is a statistical measurement and it's not impossible for randomness to produce results wildly different from the expected average.

        Consumer electronics have a typical lifespan of ~2 years because their solder joints grow metal whiskers. They grow metal whiskers because, after California adopted the EU's 5% maximum lead content for solder, manufacturers opted to eliminate lead from their solder altogether.

        The 5% lead standard was developed by NASA's Materials Research Lab based on Apollo-era experiments with lead-free solder joints [nasa.gov] in booster rockets (because lead is heavy, and there's a LOT of solder joints in a gigantic booster rocket). Short version: lead-free solder was a disaster, because the high current levels in many of the boosters' subsystems (especially LOX pumps) caused the nearly-instantaneous growth of tin whiskers that shorted out the rockets' electrical systems, causing blowy-uppy events.

        NASA eventually determined that 5% was the minimum necessary proportion of lead in solder to prevent the development of tin whiskers in solder joints. The EU adopted that as its standard for consumer electronics, in an effort to reduce the amount of lead entering the waste stream. California - the seventh-largest economy on Earth - did likewise. CE manufacturers, on advice of their lawyers, decided that, if 5% was the maximum allowed for products sold in Cali, 0% would be even better from a liability standpoint. When their engineers pointed out that lead-free solder causes even moderate-current consumer electronics to grow device-killing tin whiskers after 2 years or so, their C suites promptly had orgasms over the prospect of the profits to be reaped from the infinite stream of replacement device sales, and lead-free solder as the CE default was born.

        FWIW, also courtesy of NASA, we know that a 2-mil coating of polyurethane laquer is sufficient to contain more than 90% of tin and other metallic whisker growth. It also makes CE devices a lot less of a target-rich environment for metal-whisker-induced short circuits. Manufacturers know this, of course (again, courtesy of NASA [nasa.gov]), so they go to great pains not to employ polyurethane protective coating in CE devices.
