Batterie a stato solido
Le batterie a stato solido rivoluzionano l'immagazzinamento dell'energia, migliorando la sicurezza e la densità energetica grazie agli elettroliti solidi.

Le batterie allo stato solido (SSB) rappresentano un salto di qualità nella tecnologia di accumulo dell'energia, in quanto sostituiscono gli elettroliti liquidi con materiali solidi per migliorare la sicurezza e la densità energetica. Queste batterie utilizzano elettroliti a base di ceramica, vetro o solfuro, che riducono significativamente i rischi associati a perdite e infiammabilità. La loro architettura consente un funzionamento a tensione più elevata e una migliore stabilità termica, rendendole interessanti per i veicoli elettrici e l'elettronica portatile. Rimangono sfide da affrontare per ottenere batterie scalabili produzione e garantire la stabilità a lungo termine dell'interfaccia tra elettrodi ed elettroliti solidi.

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.
