ROI Calculation Logic

Assuming a 20% average improvement in non-aqueous electrolyte secondary battery cycle life. For a company producing 1 million EV batteries annually, this could reduce warranty-related battery replacement costs by 10% (estimated at $350/unit (AI est.)). This translates to a potential annual cost reduction of 1 million units × $350/unit (AI est.) × 0.10 = ~$35M (AI est.). Additional economic impact could arise from increased product unit prices due to higher capacity.
