Estimate annual lithium carbonate equivalent (LCE) input from your battery production plan. All inputs are editable; defaults are examples, not industry benchmarks.
Illustrative annual material input
889 tonnes LCE
167 tonnes contained lithium equivalent
1 GWh × 1,000 × 0.8 kg LCE/kWh ÷ 0.9 = 889 tonnes LCE
The figures describe a scenario, not an order specification.
How the calculation works
Input LCE (tonnes) = annual output (GWh) × 1,000 × intensity (kg/kWh) ÷ (yield / 100). One GWh equals one million kWh; one tonne equals one thousand kilograms.
Contained lithium equivalent = LCE ÷ 5.323, using an approximate stoichiometric mass ratio for Li₂CO₃ to its lithium content. This is a mass comparison, not a conversion-efficiency estimate or product-grade certificate.
The intensity must come from your own chemistry and engineering assumptions. The yield represents material utilisation; this simple model does not separately model scrap recirculation, inventory, impurities, recovery or product qualification.
