Scheduled maintenance, including cleaning contacts, ensuring proper ventilation, and monitoring temperature levels, is vital in prolonging the lifespan of energy storage systems. Moreover, adopting smart technology for predictive maintenance allows operators to schedule service visits based on real data rather than routine checks, resulting in increased operational efficiency and minimized decay.

6. ECONOMIC IMPACT OF DECAY
The decay of energy storage systems carries substantial economic implications for both consumers and businesses. For individuals, declining battery capacity translates to shorter lifespans and additional costs for replacements. Small businesses, particularly those dependent on reliable energy, may incur increased operational costs or losses due to degraded storage solutions.

At the commercial level, understanding deterioration mechanisms enables companies to forecast maintenance costs accurately. By integrating advanced energy management systems, businesses can optimize their storage solutions, minimize decay impacts, and ultimately maximize efficiency. This can lead to improved profit margins and sustainability, creating a ripple effect throughout various sectors reliant on energy storage.

7. FUTURE DEVELOPMENTS IN ENERGY STORAGE
Ongoing research aims to enhance energy storage technologies, targeting reductions in decay rates while improving performance metrics. Emerging battery technologies, like solid-state batteries and advanced lithium-sulfur models, show promise in mitigating decay and extending lifespan compared to conventional lithium-ion systems. Furthermore, the integration of AI and machine learning into energy management practices can revolutionize how operators predict performance and optimize charging protocols, directly addressing decay concerns.

The push for sustainability will likely continue to foster research and development within the energy storage industry, addressing the fundamental challenges associated with decay.
