Product introduce

This cell is specially designed for lithium ion battery’s research. It consists of 5 parts as shown below.

Part size: Stainless steel sleeve: outer diameter 25.4mm

Teflon body: inner diameter: 13 mm

Material: SS316 stainless steel

The cell is used in conjunction with an acrylic rack. The acrylic rack is designed to allow the cell to work upright during testing.

Two types of racks are available:

T5: Holds 5 cells. Dimension: 500 x 70 * 90 mm

T8: Holds 8 cells. Dimension: 800 x 70 * 90 mm

Usage Guide

The cell is placed vertically on the rack during measurement. In each cell, there are 5-10 drops of electrolytes required to wet the electrode and separator. We recommend to wrap the cells with para-film after assembly in Glove-box in order to ensure better sealing. The electrolyte will be kept in the cap even when excess electrolyte is added. Note the gap between the steel rod and Teflon body is very small.

Typical Procedures

The working electrode consisted of active material (e.g., TiO2 NSHSs), a conductive agent (carbon black, Super-P-Li), and a polymer binder in a 70:20:10 weight ratio.Mix and put on copper foil, fry in vacuum oven.

Pure lithium metal as both the counter electrode and the reference electrode at room temperature.

In Swagelok-typecell, put working electrodes first,then separator, then the lithium metal.

How to put in separator: 

Stick lithium metal on the separator, wet with electrolyte, so that separator can stick onto it. And then put them into swagelok-type cells.
