Diamond nuclear batteries are really not a fantasy！

Atomic energy batteries, also known as nuclear batteries or radioactive isotope batteries, work by utilizing the energy released by nuclear isotope decay to be absorbed and converted into electrical energy through semiconductor converters. Thanks to the excellent physical and chemical properties of diamond, diamond nuclear batteries provide an ideal energy solution for devices with long lifespan and low power requirements. They have shown great potential in fields such as aerospace, AI equipment, medical devices, MEMS systems, advanced sensors, small drones, and micro robots.

Compared to Si, GaN, SiC, etc., the bandgap width of diamond semiconductor materials is as high as 5.45 eV, with the greatest advantage being higher carrier mobility (hole: 3800 cm2V-1s-1, electron: 4500 cm 2V-1s-1), higher breakdown electric field (>10 MVcm-1), and larger thermal conductivity (22 WK-1cm-1). Its intrinsic material advantage is that it has the highest thermal conductivity in nature and the highest bulk material mobility, which can meet the needs of future high-power, strong electric field, and radiation resistance, making it an ideal material for making power semiconductor devices.

The use of diamond in nuclear batteries will have the following advantages:

1. High energy density: The energy density is more than 10 times that of ternary lithium batteries, and can store 3300 megawatt hours of electricity in a 1 gram battery;

2. High service life: capable of generating electricity for 50 years without the concept of electrochemical battery cycles (2000 charge and discharge).

3. High stability: The power generation of atomic energy batteries is stable and will not change due to harsh environments and loads. They can operate normally within the range of minus 120 degrees Celsius and minus 60 degrees Celsius, and there is no self discharge;

4. High safety: No fire, no explosion, and no external radiation for acupuncture and shooting. Medical devices such as pacemakers, artificial hearts, and cochlea that can be suitable for use in the human body;

5. Environmentally friendly: The half-life of "Ni-63" is 36963.51 ± 54.79 days (101 years). After the decay period, the nickel 63 isotope, which serves as a radioactive source, becomes a stable isotope of copper and is non radioactive, posing no threat or pollution to the environment. Therefore, unlike existing chemical batteries, this nuclear battery does not require expensive recycling processes, eliminating the waste disposal problem after the battery's service life expires, and is very environmentally friendly.

CSMH is deeply involved in the diamond field and possesses leading production technology and product quality. Its core products include diamond heat sinks, diamond wafers, diamond windows, and diamond heterojunction integrated composite substrates. The thermal conductivity of diamond heat sinks reaches 1000-2000W/(m.k), and the diamond wafer Ra<1nm. It is currently used in high-power lasers, new energy vehicle IGBTs, photovoltaics, radar, aerospace, and medical devices.
