A Spin-Polarisation Battery: Stored Energy and Discharge Power of an Aligned-Spin Cell
Year: 2026
Type: article
Abstract: This paper presents a complete design study of an energy storage cell that holds its charge as aligned nuclear spin in a solid working body, computed throughout from stated assumptions. A cell of one litre stores 0.18 kJ, discharges at 0.3 W over the stated discharge interval, and returns a round-trip efficiency of 36.0 percent over a day of storage; the same litre in conventional lithium chemistry stores 900.0 kJ. A ten-litre cell stores 1.80 kJ at a round-trip efficiency of 36.0 percent. Every figure is a computed result of the stated model and nothing was built or tested: the study is SIMULATED, NOT MEASURED, and its limits are stated as plainly as its performance.
