Las baterías de estado sólido (SSB) representan un salto transformador en la tecnología de almacenamiento de energía, ya que sustituyen los electrolitos líquidos por materiales sólidos para mejorar la seguridad y la densidad energética. Estas baterías utilizan electrolitos de cerámica, vidrio o sulfuro, que reducen significativamente los riesgos asociados a las fugas y la inflamabilidad. Su arquitectura permite un funcionamiento a mayor tensión y una mayor estabilidad térmica, lo que las hace atractivas para los vehículos eléctricos y la electrónica portátil. Sin embargo, sigue siendo difícil conseguir fabricación y garantizar la estabilidad a largo plazo de la interfaz entre electrodos y electrolitos sólidos.

Performance Evaluation of a Flexible Power Point Tracking Strategy for Extending the Operational Lifetime of Solar Battery Banks
Published on 2026-02-01 by Mario Orlando Vicencio Soto, Hossein Dehghani Tafti @MDPI
Abstract: Standalone photovoltaic systems play an important role in providing reliable renewable energy in remote areas. These systems depend heavily on battery energy storage, especially lithium iron phosphate batteries, which are known for their safety and long cycle life. However, battery degradation remains a major challenge, as high charging currents, temperature variations, and wide state-of-charge fluctuations introduce electro-thermal stress that reduces the useful lifetime of the storage system. [...]
Our summary: This paper presents a Flexible Power Point Tracking strategy to reduce battery stress and extend the lifetime of lithium iron phosphate batteries in standalone photovoltaic systems. A fuzzy-logic-based controller is implemented to stabilize current peaks, temperature, and state-of-charge variations. Results indicate a 7% improvement in battery lifetime compared to traditional methods.
