In this study, we implement a phase-field model to investigate two electrochemical reaction models: the Butler–Volmer and the Marcus–Hush–Chidsey formulation. We assess their effect on the spatial and temporal evolution of the FePO 4 and LiFePO 4 phases. . Optimizing the charging rate is crucial for enhancing lithium iron phosphate (LFP) battery performance. The substantial heat generation during high C-rate charging poses a significant risk of thermal runaway, necessitating advanced thermal management strategies. The low solubility of lithium (Li) in some of these host lattices cause phase changes, which for example happens in FePO. .
Recent pricing trends show standard home systems (3-10kW) starting at $8,000 and community microgrids (50kW-2MW) from $100,000, with flexible financing options including PPAs and community solar loans available. . A recent study highlights that implementing energy storage technologies, such as lithium-ion batteries and pumped hydro, could lower Brazil's electricity system costs by up to 16% by 2029. These solutions are expected to improve system reliability and increase the integration of renewable energy. . With Brazil"s energy storage market set to be worth as much as BRL 7. 5 billion and 5 GWh of capacity through 2027, demand could be high for the 2025 procurement exercise. Tariffs add 18–30% to final prices.
