14500 Cylindrical Battery Case Cap Kits(100 sets/pack)

RESEARCH GRADE MATERIAL

Product Overview

This premium cell assembly kit is a dedicated packaging solution engineered specifically for 14500 cylindrical cells (Model: 14500, Code: 07002401). Built using high-quality imported Japanese nickel-plated steel, this kit streamlines experimental battery workflows by combining premium steel casings, upper/lower insulating gaskets, and specialized anti-explosion caps featuring factory pre-welded aluminum tabs. Designed to satisfy rigorous laboratory scaling and testing requirements, it minimizes manual preparation errors and delivers high-utility performance for small-format cylindrical battery research.

Key Features & Advantages

Pre-Welded Tabs for Instant Assembly: Anti-explosion top caps come directly with integrated 7×3×0.15mm aluminum tabs. Eliminates manual metal cutting and initial spot-welding preparation.
Premium Imported Steel Casing: Formed using premium Japanese nickel-plated steel to provide exceptional structural integrity. High mechanical resistance prevents deformation under baseline pressures.
High-Safety Anti-Explosion Valve: Built-in safety rupture disc maintains a precise burst threshold between 3.2–4.0 MPa. Releases built-up internal pressure smoothly to counter overcharging risks.
Ultra-Low Internal Resistance: Overall cap contact resistance restricted below 0.5 mΩ. Lowers physical ohmic drops and heat generation during high-rate battery characterization.
Complete Turnkey Lab Sourcing: Supplies matching casings, gaskets, and tab-welded caps in a single box. Safeguards researchers from dimension mismatch complications.

APPLICATION SCOPE: University laboratories evaluating novel active material chemistries; EV or electronics R&D divisions creating 14500 prototype cells; and industrial developers testing micro-sensor, portable device, or medical tool battery configurations.

PACKAGING: Contains 100 sets neatly packed within a professional distribution box. Each individual assembly kit consists of 1x 14500 nickel-plated steel casing, 1x anti-explosion cap with pre-welded aluminum tab, 1x upper insulating gasket, and 1x lower insulating gasket.

IMPORTANT NOTICE: Exclusively meant for standard flat-head 14500 bare cells without pre-installed protective circuit boards (PCBs/BMS). Store in a dry, ventilated environment at 0–35°C (Humidity ≤75% RH) away from heat or corrosive gases. Wear appropriate protective gloves and safety goggles during cell crimping operations. For laboratory research use only.
