Is lithium-ion battery aging a threat to energy storage systems?

Lithium-ion battery aging represents a fundamental challenge affecting both performance degradation and safety risks in energy storage systems. This review presents a systematic examination of aging mechanisms, advanced characterization techniques, and state-of-the-art prediction methodologies.

What is battery aging?

Battery aging represents a complex multi-physics phenomenon involving intricate coupling among electrochemical, thermal, and mechanical processes.

How do we decouple aging mechanisms in lithium ion batteries?

First, conduct separate studies on different aging mechanisms to decouple the degradation mechanisms [117, 118]. Under low temperatures, perform high-rate charging to induce lithium plating in the battery, followed by high-temperature resting to accelerate LLI aging.

What are the different types of battery aging models?

The main types of battery aging models include mechanism models, ECMs, empirical models, data-driven models, and hybrid models [7, 21, 85, 172, 173]. Mechanism models are battery performance models established based on the theoretical foundation of internal electrochemical reactions.

Are lithium-ion batteries a viable energy storage technology?

Due to their declining costs 2 and wide applicability, lithium-ion (Li-ion) batteries are one of the fastest-growing grid energy storage technologies. However, their investment costs are still relatively high and therefore adequate sizing and control strategies are required to maximize battery life and energy throughput.

Is battery aging irreversible?

Battery aging is an irreversible process, primarily manifested by a decrease in capacity and an increase in internal resistance. It is usually the result of the combined effects of multiple side reaction processes, related to various physical and chemical mechanisms, with very complex degradation mechanisms and aging forms.
