Solid-state batteries
As baterias de estado sólido revolucionam o armazenamento de energia, aumentando a segurança e a densidade energética por meio de eletrólitos sólidos.

Solid-state batteries (SSB) represent a transformative leap in energy storage technology, replacing liquid electrolytes with solid materials to enhance safety and energy density. These batteries utilize ceramic, glass, or sulfide-based electrolytes, which significantly reduce risks associated with leakage and flammability. Their architecture enables higher voltage operation and improved thermal stability, making them attractive for electric vehicles and portable electronics. Challenges remain in achieving scalable manufacturing processes and ensuring long-term interface stability between electrodes and solid electrolytes.

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. [...]

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.
