What is the cap resistance specification for the 14500 cylindrical cell can assembly, and how does it affect cell performance?
The cap resistance is ≤ 0.5 Ω. This low resistance minimizes internal power loss and heat generation during discharge, which is critical for high-rate applications and consistent cell assembly quality.
What are the dimensions of the pre-welded aluminum tab on the cap assembly, and is it compatible with common cathode materials?
The pre-welded aluminum tab measures 7 × 3 × 0.15 mm. It is designed for welding to cathode materials such as NMC or LFP, and its thin profile (0.15 mm) facilitates low-resistance connections while maintaining compatibility with standard tab welding equipment.
What is the safety valve burst pressure range for the 14500 cylindrical cell can assembly, and how does it ensure cell safety?
The safety valve burst pressure is specified at 3.2–4.0 MPa. This range ensures the cell can vent safely under overpressure conditions, preventing catastrophic rupture while maintaining structural integrity of the nickel-plated steel can.
This 14500 matched component kit supplies 100 cell assemblies combining a Japanese nickel-plated steel can, a cap with a pre-welded 7 × 3 × 0.15 mm aluminum tab, and upper/lower insulating gaskets, with cap resistance ≤0.5 Ω and a safety valve burst pressure of 3.2–4.0 MPa.
Positive
- Complete matched-component kit: Each pack provides 100 matched sets of nickel-plated steel can, cap assembly, and upper/lower insulating gaskets, so the 14500 structural components are supplied as a coordinated set.
- Pre-welded aluminum tab included: The cap assembly arrives with a 7 × 3 × 0.15 mm aluminum tab already welded, providing a pre-attached electrical connection for the cell build.
Trade-offs
- Fixed overpressure release window: The safety valve burst pressure is fixed at 3.2–4.0 MPa, so the overpressure response of the assembled cell is predetermined by the cap rather than adjustable during assembly.
- Fixed pre-welded tab geometry: Because the aluminum tab is pre-welded at 7 × 3 × 0.15 mm, the electrical connection footprint is set by the kit and cannot be changed without further modification.
