During this process, lithium inventory is consumed to form the solid electrolyte interphase (SEI), which in turn determines the battery lifetime. To tackle the vast parameter space and complexity of formation, we employ a data-driven workflow on 186 lithium-ion battery cells across 62 formation protocols.
The start of formation can be defined as the point at which the cell is electrically connected, and the first charge is initiated. Fig. 1 Schematic overview of the formation process and manuscript.

Volume 34, article number 1890, (2023) To become entirely operational, lithium-ion batteries (LIBs) must go through a formation process after assembly and electrolyte injection. To provide steady and repeatable cycling with the highest level of energy efficiency, a particular formation procedure is essential.
Formation cycling is a critical process aimed at improving the performance of lithium ion (Li-ion) batteries during subsequent use. Achieving highly reversible Li-metal anodes, which would boost battery energy density, is a formidable challenge. Here, formation cycling and its impact on the subsequent cycling are largely unexplored.
The formation process for lithium ion batteries typically takes several days or more, and it is necessary for providing a stable solid electrolyte interphase on the anode (at low potentials vs. Li/Li +) for preventing irreversible consumption of electrolyte and lithium ions.
Battery cell formation is part of cell conditioning. Cell conditioning also includes various quality test steps and quality sorting. The purpose of the formation process is to electrochemically activate the cell so that its subsequent performance is positively influenced. The formation process is critical for a number of reasons.
Increasing the speed of battery formation can significantly lower lithium-ion battery manufacturing costs. However, adopting faster formation protocols in practical manufacturing settings is challenging due to a lack of inexpensive, rapid diagnostic signals that can inform possible impacts to long-term battery lifetime.
