An industry-built tool for comparing battery technologies at the product level - from raw materials to full-cell energy and cost. Now including new cell architectures.
Our Toolset
Built for battery engineers
From electrode formulation to full-cell COGS — every parameter, every chemistry, one platform.
Simulate Full-Cell Performance
Generate full-cell discharge curves from half-cell inputs. Model usable capacity, nominal voltage, and N:P ratio across 13+ cathode and 18+ anode chemistries — including blended anodes and anode-free configurations.
Break Down Cost to the Dollar
See a complete cost stack from active materials through COGS — BOM, direct labor, energy, depreciation, SG&A, R&D, financing, profit, and warranty. Override any input with live price data.
Model Validation
Results you can trust
CellVision predictions are benchmarked against real market prices from the Shanghai Metals Market (SMM). Across cylindrical and prismatic formats, modeled costs track observed prices closely.
Cylindrical Cells — $/cell
CellVision modeled costs for 18650 and 21700 cells compared against Shanghai Metals Market spot prices, May 2026.
Prismatic Cells — $/kWh
CellVision modeled costs for prismatic LFP cells across a range of capacities compared against Shanghai Metals Market spot prices, May 2026.
BYD Blade — Prismatic Teardown
CellVision modeled cell parameters compared against a published teardown analysis of the BYD Blade prismatic LFP cell.
Tesla 4680 — Cylindrical Teardown
CellVision modeled cell parameters compared against a published teardown analysis of the Tesla 4680 cylindrical cell.
SMM prices represent market spot prices for cells sold in China and reflect a range of manufacturers and quality levels. CellVision models a single manufacturer at scale, so some divergence is expected.
