Dispenses metered micro-volume electrolyte into compact pouch cavities under controlled conditions to achieve uniform saturation.
Why this machine: Micro-cells have zero tolerance for overfilling. This system uses micro-dosing technology to ensure accurate fill weights without residual dripping.
Ideal User: TWS and medical device battery manufacturers.
When to choose: When electrolyte volume tolerance is extremely narrow and even micro-level overfill or underfill directly affects internal pressure, cycle life, or safety performance.

This section identifies electrolyte injection as a key step in miniature pouch cell assembly.
Measured electrolyte volumes are introduced into pre-sealed shells prior to vacuum sealing.
Packaging focuses on fluid handling and sealing interfaces.
Electrolyte injection is executed by the patented rotary-table filling equipment for pouch-type Bluetooth lithium batteries, which indexes cells through sequential filling positions.
The rotary configuration enables controlled small-volume dosing while maintaining continuous production rhythm suited to miniature pouch formats.
