In lithium-ion battery R&D laboratories, the entire preparation process of pouch cells is highly sensitive to moisture and oxygen contamination. The traditional “multi-equipment cross-environment transfer” model easily introduces impurities and undermines experimental reproducibility. This article focuses on the solution of integrating a small coating machine, manual slicer, stacking fixture, and electrolyte injector in a vacuum […]

The “Oxygen-Forbidden Zone” for Lithium Metal Anode Research: Standard Operating Protocols for Achieving <0.1ppm H₂O/O₂ in Glove Boxes
Introduction Lithium metal is the “holy grail” of next-generation battery anodes, boasting ultra-high theoretical capacity (3860 mAh/g) and the lowest redox potential (-3.04 V vs. SHE). However, its extreme chemical reactivity with moisture and oxygen poses a fatal challenge: trace H₂O/O₂ (≥0.1ppm) triggers rapid surface oxidation, dendrite growth, and irreversible capacity decay, rendering experimental data […]
Building a Coin Cell Assembly Line from Scratch: Practical Space Layout for Glove Boxes, Small Hydraulic Presses, and Crimping Machines
Abstract Aiming at the scenario of small-batch coin cell R&D in laboratories, this article provides a set of immediately implementable solutions for internal equipment layout of glove boxes, cable and air pipe routing, and material access route design for transition chambers. It also attaches a checklist for semi-automatic assembly line construction. This guide helps researchers […]
