Summary: Lithium batteries typically retain stored energy for 1–3 years under optimal conditions. This article explores their storage lifespan, factors affecting performance, and real-world applications across industries like renewable energy and transportation. Environment significantly affects the battery's characteristics, particularly regarding temperature. Most packs can handle about 500 full charge cycles. The effectiveness varies widely in applications such as electric vehicles and grid. Most home solar battery systems sold today use lithium iron phosphate or LFP cells due to the longer lifespan and very low risk of thermal runaway (fire).

Authors to whom correspondence should be addressed. Lithium iron phosphate (LFP) batteries have emerged as one of the most promising energy storage solutions due to their high safety, long cycle life, and environmental friendliness.
Additionally, the explosion concentration range of the mixture gas also increases accordingly. This model revealed the inner pressure increase and thermal runaway process in large-format lithium iron phosphate batteries, offering guidance for early warning and safety design. 1. Introduction
Current collectors are vital in lithium iron phosphate batteries; they facilitate efficient current conduction and profoundly affect the overall performance of the battery. In the lithium iron phosphate battery system, copper and aluminum foils are used as collector materials for the negative and positive electrodes, respectively.
Resource sharing is another important aspect of the lithium iron phosphate battery circular economy. Establishing a battery sharing platform to promote the sharing and reuse of batteries can improve the utilization rate of batteries and reduce the waste of resources.
Overcharging is extremely detrimental to lithium iron phosphate batteries; it not only directly causes microscopic damage to the cathode material but also induces chemical decomposition of the electrolyte and the generation of harmful gasses, which can lead to thermal runaway, fire, explosion, and other catastrophic consequences in extreme cases.
