Design Uranium-Based Perpetual AA Battery

Job ID: 40473698

Budget: $5,000 – $10,000 USD

I need a complete engineering pathway for an AA/AAA-sized battery that will draw continuous power from a uranium source so the cell never requires replacement or recharge. The target deployment is industrial robotics, so the design must combine very high energy output with a compact envelope and rock-solid performance across a wide temperature range.

The work begins with assessing the most suitable uranium isotope, energy conversion method (betavoltaic, thermoelectric, or a hybrid you can justify), and the shielding that keeps emitted radiation below industrial safety limits while still meeting the tight geometry of standard alkaline cells. From there the project flows into electro-mechanical layout, materials selection, lifetime modelling, and a plan for automated production that could scale.

Because these batteries will be mounted inside mobile robotic arms and autonomous platforms, weight and vibration resistance matter as much as raw output. Please integrate those realities into the CAD, thermal, and radiation simulations (MCNP or GEANT4 for shielding, COMSOL or ANSYS for heat, any preferred CAD suite for packaging). Regulatory strategy—DOT, NRC, IAEA shipping classifications—must be factored in early so we avoid redesign later.

Deliverables
• Feasibility dossier: decay-to-power calculations, shielding analysis, predicted lifetime curve
• Detailed mechanical and electrical CAD files ready for prototype machining/printing
• Thermal and radiation simulation reports with raw model files
• Compliance roadmap outlining tests, documentation, and licensing steps for U.S. and EU deployment
• Prototype assembly procedure with a bill of materials and sourcing notes for radioisotopes, converters, and encapsulants

Acceptance criteria
• Continuous power density ≥ 50 mW/cm³ at 25 °C over a 20-year projection
• Exterior surface dose rate ≤ 0.5 µSv/h at contact
• Dimensions fit within standard AA (14.5 mm × 50.5 mm) or AAA (10.5 mm × 44.5 mm) tolerances without adapter sleeves
• Operable from –40 °C to +85 °C with <5 % performance drift

If you have a proven track record in nuclear materials, advanced battery research, or radiation-hardened electronics design, your insight will be invaluable to bringing this perpetual power source to life.
