Supercapacitor Battery Case Cylindrical Cell Assembly Hardware with Built In Safety Vent

Product Overview

This high-performance cylindrical supercapacitor battery case set is purpose-built to meet the rigorous physical and electrochemical requirements of advanced energy storage prototyping. Engineered around the industry-standard 26650 form factor, the housing provides a secure, hermetically sealed enclosure optimized for electric double-layer capacitors (EDLC), hybrid ultracapacitors, and advanced electrochemical energy storage systems. Its precision-drawn metal wall construction ensures superior mechanical strength and structural integrity during dynamic charge-discharge cycling and long-term lifespan evaluation.

Designed primarily for battery laboratories, academic research institutions, and industrial pilot lines, this cell enclosure kit supports comprehensive fabrication workflows. The system allows researchers to test and validate novel electrode formulations, high-surface-area carbon nanomaterials, pseudocapacitive metal oxides, and high-conductivity electrolyte chemistries with consistent dimensional stability and zero electrolyte leakage.

Operating under demanding electrochemical parameters requires complete confidence in cell-level safety. Equipped with a calibrated 2.5 MPa pressure-actuated relief vent built directly into the top cap, this housing mitigates overpressure risks resulting from volatile solvent gasification or accidental electrical abuse. Combined with dedicated internal dielectric insulation and resilient sealing components, the casing provides dependable containment under aggressive cycling conditions.

Key Features

• Calibrated Pressure Relief Mechanism: Features an integrated top-cap safety valve engineered to open precisely at 2.5 MPa, venting internal gas accumulation during extreme thermal or overcharge events to prevent catastrophic can rupture and ensure user safety.
• Standardized 26650 Form Factor: Manufactured with strict outer dimensions of 26 mm in diameter, 67 mm in height, and a uniform 0.25 mm wall thickness to ensure complete compatibility with laboratory grooving tools, automated winding machinery, and precision crimping dies.
• Hermetic Sealing Architecture: Includes a precision-machined top cap measuring 17.5 mm in diameter by 4.05 mm in height paired with an elastomeric O-ring seal to establish an impervious barrier against ambient moisture ingress and volatile electrolyte solvent evaporation.
• High-Dielectric Internal Insulation: Outfitted with a dedicated top insulator ring measuring 16.1 mm in diameter and 2.6 mm in thickness, providing critical electrical isolation between the internal electrode stack, outer casing body, and positive terminal assembly.
• Low-Resistance Internal Current Collector: Incorporates a high-purity aluminum spacer component designed to maintain uniform axial contact pressure, optimize internal current distribution, and lower equivalent series resistance (ESR) across high-rate discharge regimes.
• Chemical and Electrochemical Resilience: Fabricated from corrosion-resistant metal alloys that resist severe oxidative breakdown, pitting, and chemical degradation when exposed to organic solvents, ionic liquids, or aqueous electrolytes.
• High-Throughput Research Packaging: Delivered in standardized quantities of 50 units per bag, ensuring batch-to-batch consistency, contamination-free storage, and streamlined handling across large-scale experimental matrix testing.
