IP Direct Fill® for Hard Case Cells

The IP Direct Fill® Technology uses a volumetric dosing pump, a switch valve to select vacuum, inert gas or rinsing solvent and a filling valve that directly connects the dosing pump via a short filling stud tightly to the filling hole of the hard case cell. No pre-chamber is used. The advanced valve technology allows the supply of all media to the filling stud (electrolyte, vacuum, inert gas, solvent).

Features 

  • IP Direct Fill® with dosing pump (no pre-chamber) thus no gas solution into the electrolyte
  • Rapide one-step filling maintains electrolyte composition
  • Precise Filling with high accuracy:<=+/- 0,5% at high process stability
  • Direct evacuation with down to 0,4 mbar absolute pressure in the cell
  • IP Cell Protection® & IP High Pressure Fill® up to 40 bar
  • The level of filling pressure, pressure curves and pressure cycles can be freely adjusted
  • Incl. leakage test and pressure monitoring,  individual feedback full traceability of filling parameters
  • Dosing quantity according to customer requirements
  • Clean filling process without contamination of the cell surface

Electrolyte Injector - from research and development to fully automatic production

The Electrolyte Injector brings the advantages of the IP Direct Fill® Technology into your cell production. This machine can easily be adapted to produce cylindrical and prismatic cells. It is designed modular so the machine can be generated according to your demand: 

  • Stainless steel frame assembled from standard beams and connecting cubes form segments
  • Similar basic segments can accommodate filling Units, media tanks and distribution, control and interfaces, soaking devices, plugging stations and many more
  • Machine frame variants for dry room: manual loading or for robot loading: glove box
  • Dosing stations are available with different max. filling pressures: Standard 6 bars, High Pressure 20 bars or even 40 bars with IP PS Cell Protection (patent pending)
  • Filling units can be combined out of different dosing and cell stations to customer’s needs
  • Filling is always automatic
  • The Electrolyte Injector can be expanded later on by further filling stations or by complete segments
  • Atmosphere control of the ATEX areas
  • Full traceability of the filled cells and its parameters, rejects are notified and sorted out

 

Advantages of IP Direct Fill®:

  • Precise filling - up to 5 times more accurate
  • Rapid filling - up to 4 times faster
  • Clean filling - makes cell washing an unnecessary expense
  • Safe filling - less reject rate
