Titanium Cathode Plate With Cu‑Ti Composite Lug For Lithium Cobalt Nickel Electrowinning
Published by Engineering Team, Shaanxi Qianyi Tuoda Technology Co., Ltd on 2026-10-25
1. Product Identity
We are professional titanium component manufacturer from Shaanxi Baoji China. Titanium cathode plate is core consumable component for hydrometallurgical electrowinning process. Different from ordinary titanium sheet, it is assembled with copper‑titanium composite conductive lug to lower contact resistance. Strict flatness and surface roughness control are implemented to guarantee smooth metal stripping after electrolytic deposition. Widely adopted for lithium, cobalt, nickel and non‑ferrous metal electrowinning workshops. We supply semi‑finished titanium substrate and fully‑assembled finished cathode plate per customer cell‑tank drawing.

4. Mechanical & Corrosion Performance
-
Gr1 Tensile Strength ≥240 MPa; Yield ≥170 MPa; Elongation ≥24%
-
Gr2 Tensile Strength ≥345 MPa; Yield ≥275 MPa; Elongation ≥20%
-
Electrochemical Performance: Stable passivation performance in acidic brine electrolyte; Cu‑Ti composite lug greatly reduces contact resistance compared with simple copper bolt connection, cutting power consumption for long‑time electrolysis.
-
Process‑oriented performance: Uniform surface texture prevents deposited metal from over‑adhesion; excessive scratch or pit will cause metal embedding and difficult stripping, increasing manual workload.
-
Processing note: Welding zone must avoid iron contamination to prevent local electrolytic corrosion spot.
5. Full Size Range
-
Cathode substrate dimension: Custom length × width × thickness matching electrolytic cell inner size
-
Composite lug: Custom lug size, mounting position according to power bus‑bar layout
-
Edge treatment: Insulating edge strip / edge shielding groove optional to avoid side‑edge deposition
-
Custom options: Reserved hanging hole, anti‑deformation reinforcing rib, special surface texture for stripping optimization.
6. Surface Treatment Options
-
Pickled matte surface: Standard for most electrowinning scenarios, balance stripping effect and service life.
-
Fine grinding surface: Controlled roughness, for high‑purity metal easy‑stripping requirement.
-
Degreasing & passivation: Remove processing oil residue before delivery, avoid electrolyte pollution.
-
Edge insulation assembly: Install anti‑deposition insulating strips on four sides of cathode plate.
