ROI Calculation Logic

Implementing this technology in solid-state batteries could mitigate performance degradation in low-temperature environments, extending EV range in cold regions and improving energy efficiency for stationary storage systems. For example, assuming an average 5% improvement in energy loss and a 10% extension in component lifespan compared to conventional solutions, an estimated ~$1.5M/year (excluding initial investment) in operational cost reduction and enhanced product competitiveness could be achieved. This translates to an efficiency improvement of approximately $16.50/unit (EV) or $1.65/kWh (stationary) per year for 100,000 EVs or a 1GWh stationary battery system (AI est.).
