FIXTURE-21700 FOR NICKEL REMOVER MACHINE

The FIXTURE-21700 FOR NICKEL REMOVER MACHINE is a positioning fixture for holding 21700 cylindrical lithium cells during nickel-tab removal or battery-pack refurbishment work. It matches buyer searches such as 21700 nickel remover fixture, 21700 cell positioning jig, nickel tab removal fixture, battery cell holder for nickel remover and is used with a compatible nickel remover machine so the cell can be presented consistently to the cutting/removal mechanism. A dedicated fixture reduces the need to hand-position a loose cylindrical cell close to a moving tool.

Nickel removal is a mechanical rework step used when dismantling battery packs, correcting welded tabs or preparing reusable cells for inspection. The fixture's job is alignment and support; it does not determine whether a previously used cell is electrically safe for reuse. Cells removed from packs should still be checked for physical damage, voltage, internal resistance and other quality criteria before being returned to service.

A 21700 fixture must match the cylindrical cell diameter and the working geometry of the nickel remover machine. Correct centering helps place the existing nickel tab in the intended cutting area and reduces side-loading on the cell can. Consistent positioning also improves repeatability across multiple cells, which is useful in battery repair and recycling workflows where many similar cells are processed.

The fixture should be kept clean so metal fragments do not build up around the cell seat. Nickel off-cuts are conductive and can bridge terminals or create accidental short circuits if allowed to accumulate. The fixture should not be modified by grinding or drilling unless the machine manufacturer has provided dimensions for that change, because altered geometry can move the cell into the wrong cutting position.

Match the fixture to the 21700 cell format, the exact nickel remover machine, mounting-hole pattern, working height and blade/tool alignment. Do not substitute a fixture intended for another cylindrical format simply because the cell can be forced into the opening. For an existing machine, compare the old fixture's outer dimensions, mounting points and cell-seat position before ordering. Also check whether the machine uses additional clamps or stops that interact with the fixture during operation.

Applications

• 21700 lithium-cell nickel tab removal.

• Battery-pack dismantling and refurbishment.

• Cell recovery and inspection workflows.

• Battery repair workshops and service centres.

• R&D and prototype pack rework.

Installation Guide

Disconnect the nickel remover machine from power before replacing or adjusting the fixture. Remove conductive nickel scraps from the work area and inspect the fixture for cracks, deformation or excessive wear. Mount the fixture securely in the same alignment as the machine's cutting path, then perform a dry positioning check before running a cell through the process. Keep cell terminals insulated from loose metal fragments and do not use cells that are swollen, punctured or otherwise physically damaged. Follow the nickel remover machine's guarding and hand-clearance instructions during operation.
