Prognostics and remaining useful life (RUL) estimation for lithium-ion batteries play an important role in intelligent battery management systems (BMS). The capacity is often used as the fade indicator for estimating the remaining cycle life of a lithium-ion battery. For spacecraft requiring high reliability and long lifetime, in-orbit RUL estimation and reliability verification on ground shoul...

This paper deals with a method to detect the existence of an over-discharged cell in lithium-ion battery (LIB) pack by measuring total harmonic distortion (THD) rate voltage response. Over-discharge LIB reduces available capacity irreversible chemical reactions, resulting serious safety risks such as explosions. Even if only one exists pack, it accelerates decomposition other cells. In general,...

Reversible chemical delithiation/lithiation of LiFePO(4) was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system--the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility of a redox flow battery and high energy density of a lithium-ion battery. Distinct from the recent semi-solid lithium rechargeable flow bat...

As lithium-ion battery (LIB) cells degrade over time and usage, it is crucial to understand their remaining capacity, also known as State of Health (SoH), inconsistencies between in a pack, cell-to-cell variation (CtCV), appropriately operate maintain LIB packs. This study outlines efforts model pack SoH CtCV nickel-cobalt-aluminum (NCA) lithium-iron-phosphate (LFP) packs consisting four series...
