Conventional processing of a lithium-ion battery cell consists of three steps: (1) electrode manufacturing, (2) cell assembly, and (3) cell finishing (formation) [8, 10]. Although there are different cell formats, such as prismatic, cylindrical and pouch cells, manufacturing of these cells is similar but differs in the cell assembly step.
An injection machine (using an injection machine) is a piece of equipment used to inject a precise amount of electrolyte into the cell of a lithium-ion battery. Principle of Injection Machine: Insertion of electrolyte ring → Battery assembly → Electrolyte injection into battery → Vacuum extraction → Battery discharge.
Filling a lithium-ion battery with electrolyte liquid is a core process in battery manufacturing. Better understanding of this process will reduce costs while enabling high product quality. Nonetheless, the process has not been sufficiently examined by science yet.
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
Their operation involves complex electrochemical reactions at both electrodes, coupled with lithium ion and electron transport mechanisms, as well as thermal management processes. The manufacturing of lithium-ion batteries is an intricate process involving over 50 distinct steps.
Lithium battery manufacturing equipment encompasses a wide range of specialized machinery designed to process and assemble various components, including electrode materials, separator materials, and electrolytes, in a carefully controlled sequence.
