Building a Lithium Battery Lab from Scratch: How to Configure the Equipment? A Comprehensive Guide

Many startup teams, when setting up a lithium battery lab, often fall into a misconception: the more equipment, the better. In reality, lab configuration is more about "matching research needs" than blindly piling on equipment. Understanding the basic process of battery fabrication and testing makes equipment selection much clearer.

The first step in battery research is to turn materials into usable electrodes.

Common equipment includes:

• Mixing/Planetary Mixer: Used to prepare slurry
• Coating Machine: Coats the slurry evenly onto the current collector
• Oven: Removes solvents
• Roller Press: Improves electrode density
• Sheet Mill: Prepares standard-sized electrode sheets

The core of this step is ensuring electrode uniformity and repeatability.

After the electrodes are prepared, the assembly stage begins. Because the electrolyte is sensitive to water and oxygen, this step usually needs to be completed in a controlled environment.

Basic equipment includes:

• Glove box (inert atmosphere): for controlling water and oxygen content
• Sealing machine/pressing machine: for coin cell or pouch cell battery encapsulation

For entry-level labs, coin cell battery equipment is sufficient for most basic research needs.

After the battery is built, the most important thing is to test its performance.

Common equipment includes:

• Battery testing system (charge-discharge meter): for testing capacity and cycle life
• Electrochemical workstation: for performing cyclic voltammetry (CV), impedance (EIS), and other tests

These devices determine "what data you can see" and are one of the core configurations of a lab.

If conditions permit, some materials and structural analysis equipment can be added, such as:

• Particle size analysis, specific surface area testing
• Microstructure characterization (e.g., SEM)

However, this part requires a significant investment, and many teams choose to share resources with public platforms.

Complete equipment does not necessarily equate to strong experimental capabilities. What truly affects the results are often process details, such as coating uniformity, drying conditions, and assembly environment.

In other words: Process stability is more important than equipment stacking.

Building a lithium battery lab is essentially about constructing a complete chain from materials to performance verification. By focusing on the three steps of "preparation—assembly—testing" and configuring equipment as needed, unnecessary investment can be avoided.
