Cell Lab 26650 Cylinder Cell Case [with Anti-Explosive Cap & Insulation O-Ring, 100 pcs] – Nickel-Plated Battery Housing for Lithium-Ion Cell R&D

High-safety cylindrical case with PTC protection and pressure-release valve for reliable cell prototyping

The Cell Lab 26650 Cylinder Cell Case is a high-precision, safety-enhanced housing developed for lithium-ion battery research, prototyping, and pilot-scale assembly. Crafted from nickel-plated A3 steel, this casing offers outstanding mechanical durability, corrosion resistance, and stable performance under thermal stress.

Each case features a PTC thermistor that limits current flow above 120 °C, an anti-explosive safety cap with a pressure relief valve opening at 2.5 MPa, and a nylon insulation O-ring for effective electrical isolation. These design elements make it the preferred choice for assembling high-capacity 26650 lithium-ion cells used in EVs, energy storage systems, and R&D laboratories.

Key Features

Precision Fit for 26650 Format
Accurately dimensioned (OD 26.0 mm, ID 25.5 mm, H 68.0 mm) for consistent cell assembly and perfect alignment.

Anti-Explosive Safety Cap
Equipped with a 2.5 MPa pressure-release valve to prevent cell rupture during abnormal operation.

Integrated PTC Thermistor
Automatically interrupts current above 120 °C, mitigating risks of overheating and thermal runaway.

Durable Nickel-Plated Steel Construction
Nickel-plated A3 steel ensures mechanical strength, corrosion resistance, and extended service life.

Electrical Isolation via Nylon O-Ring
Provides reliable top-bottom insulation to minimise short-circuit risks and enhance assembly safety.

FAQ

Q1: Are these cases compatible with standard 26650 electrodes and jelly rolls?
Yes. They are manufactured to standard 26650 dimensions and fit conventional electrode windings.

Q2: Does each case include the top cap and insulation O-ring?
Yes. Each complete set includes the case, anti-explosive cap, and nylon O-ring.

Q3: Can the cap be laser or spot welded?
Yes. The nickel-plated surface provides excellent weldability and electrical contact.

Q4: What’s the function of the PTC thermistor?
It provides self-resetting over-temperature protection, cutting off current above 120 °C.

Q5: Are other sizes such as 18650 or 32650 available?
Yes. Cell Lab supplies a full range of cylindrical cases with similar integrated safety features.
