This product is a set of coin cell casings designed for battery research and small electronics assembly, compatible with CR2032, CR2025, CR2016, and CR2430 formats. Crafted from stainless steel 304 (or 316 available) with a PP sealing O-ring, each case includes positive and negative poles, spring sheets, and gaskets—all professionally cleaned before delivery for immediate use. In electrochemical research, the CR2032 variant is widely employed as a half-cell for evaluating active electrode materials, while other sizes support varied energy storage configurations. The robust 304SS construction ensures durability and corrosion resistance during repeated assembly and disassembly. This set streamlines experimental workflows by providing reliable, ready-to-use components for coin cell fabrication.

Cleaning guidelines for battery components:

1. Negative pole shells, spring sheets, and gaskets:**

1.1 Ultrasonic clean for 10-20 minutes using alkaline or neutral solvents (e.g., deionized water);

1.2 Rinse 2-3 times with deionized water, 1-2 minutes each;

1.3 Dry.

2. Positive pole shells (ultrasonic cleaning not recommended to avoid scratching):**

2.1. Soak in alkaline or neutral solvents for 10-20 minutes;

2.2 Same rinsing procedure as above;

2.3 Dry.

Note: KODAK button battery components have been professionally cleaned before delivery and are ready for use without additional cleaning.

2025 coin cell case with PP gasket

Made of stainless steel 304 or 316 with PP sealing O-ring

CR2032 is one of the most popular coin cells which is widely used for small electronics. In battery research field, CR2032 is the most popular half-cell for electrochemical performance characterizations of active electrode materials.

The name of CR2032 is defined by International standard IEC 60086. The first letter, C, identifies the chemical composition “lithium” and a nominal voltage (3V) of battery. The second letter, R, indicates a round (cylindrical) form. The first two digits encode the outer diameter of battery in mm. The last two digits are the overall height of battery in tenths of mm. Therefore, CR2032 stands for " lithium, 20 mm diameter, 3.2 mm height "
