Cell Lab 18650 Battery Steel Cases [Anti-Explosion Cap, 100 pcs] – Nickel-Plated Cylindrical Cell Housing for Safe Battery Assembly

High-integrity nickel-plated steel cases with safety vent and insulation rings for lithium-ion cell fabrication

The Cell Lab 18650 Battery Steel Cases are precision-engineered cylindrical housings designed for safe lithium-ion battery assembly and research use. Each case includes a built-in anti-explosion top cap, PTC thermistor, and insulation rings, providing reliable thermal and pressure protection during charge-discharge cycling.

Constructed from nickel-plated A3 steel, these cases offer high mechanical strength, corrosion resistance, and compatibility with most cathode/anode chemistries. The integrated pressure relief valve activates at 2.5 MPa, ensuring secure venting under abnormal conditions without rupturing the cell body.

Perfect for battery R&D laboratories, prototype production, and pilot-line assembly, this 100-piece pack enables consistent, repeatable, and safe cell fabrication.

Key Features

Built-In Anti-Explosion Cap
Pressure-activated safety valve opens at 2.5 MPa to prevent casing rupture and ensure user safety.

Top & Bottom Insulation Rings
High-grade nylon rings provide strong electrical insulation and heat resistance during welding and sealing.

Integrated PTC Thermistor
Automatically interrupts current above 120 °C, reducing risks of overheating, short-circuiting, or thermal runaway.

Nickel-Plated Steel Construction
Made from corrosion-resistant A3 steel with durable nickel plating for long-term stability and conductivity.

Bulk Packaging for Lab & Pilot Use
Supplied in packs of 100, ideal for small-batch prototyping and battery research environments.

FAQ

Q1: Are these cases compatible with standard 18650 jelly rolls?
Yes. They are designed to fit standard 18650 electrode rolls used in lithium-ion battery R&D.

Q2: Does each case include the PTC and vent cap pre-installed?
Yes, the top cap assembly comes integrated with both components.

Q3: Can these cases be used for rechargeable lithium-ion cells?
Absolutely — they are specifically made for rechargeable lithium-ion and LiFePO₄ prototypes.

Q4: Are insulation rings reusable?
Re-use is not recommended; replacing them ensures optimal insulation and sealing.

Q5: Is nickel-plating necessary for lab assembly?
Yes, nickel plating provides superior conductivity and corrosion resistance compared to bare steel.
