Design Blueprint: A Lithium-Ion Intercalation Store for a Single Residence: Cell Mass, Pack Volume, Heat Rejection and Cycle Life for Ten Usable Kilowatt-Hours

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24173757): This paper sizes a lithium-ion intercalation storage system for a single residence requiring overnight supply after rooftop solar generation ends. The duty calls for 10 usable electrical kilowatt-hours delivered at a rated power of 5 kilowatts. Working from a stated specific energy of 160 watt-hours per kilogram, an energy density of 280 watt-hours per litre, a usable depth-of-discharge fraction of 0.9, and a round-trip efficiency of 92 percent, the calculation gives a gross stored energy of 11.1 kilowatt-hours, an active-store mass of 69.4 kilograms, a complete system mass of 93.8 kilograms, and a complete system volume of 53.6 litres (0.0536 cubic metres). Full discharge at rated power lasts 2 hours, and a full recharge takes 2.32 hours at the stated charge power. Losses amount to 0.927 kilowatt-hours per complete cycle, appearing as heat at average rates of 0.2 kilowatts during charging and 0.232 kilowatts during discharge. Standing loss is 0.07 percent of the stored energy per day. Life is limited by the calendar limit, giving 4.5e+03 effective full cycles, about 15 years at the assumed cycling rate, and a lifetime delivered throughput of 45 megawatt-hours. All values are computed from the stated assumptions; the system is a design study and has not been built or measured. Status: SIMULATED, NOT MEASURED. Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
