You experience capacity loss in lithium-ion batteries due to internal chemical changes during the battery aging process. Electrochemical models show SEI layer growth, lithium plating, and electrode degradation drive capacity fade and shorten battery life.
Even high-quality lithium batteries can lose up to 20% of input energy, and for solar businesses, understanding these losses is essential to improving performance, maximizing ROI, and delivering real value to end users.
Experimental cycling tests on commercial NMC Lithium battery cells at 25°C demonstrate a clear decrease in capacity as cycles increase, eventually reaching the failure threshold (80% of nominal capacity). These results align with predictive models and real-world observations, highlighting the inevitability of capacity fade in lithium-ion batteries.
