Anodic Stripping: Kasulo

The geographic and human trauma of resource extraction is chemically indelibly written into the molecular structure of clean-energy commodities, requiring violent deconstruction to render visible.
An EV battery leaching cobalt onto a topography of its source mine. · motion: electrochemically plating and violently stripping the metal to measure its origin

wall text

Clean-energy supply chains sanitize extraction by converting raw heterogenite ore into anonymous EV battery packs. This installation reverses that refinement through anodic stripping voltammetry. An electric vehicle cathode is submerged in sulfuric acid, leaching dissolved cobalt into an aqueous electrolyte. A negative potential is applied to a cast working electrode modeled on the artisanal mining landscape of Kasulo in Kolwezi, electroplating the dissolved metal directly onto its origin topography. By sweeping the voltage positively, the plated cobalt is violently stripped back into solution, producing distinctive electrochemical current spikes that register the precise trace impurity signatures of Congolese artisanal mines.

anchor facts used

mechanism

  1. Electrolytic dissolution (dissolving a solid sample into an aqueous electrolyte for trace analysis) — A commercial EV battery pack is breached and slowly lowered into a large glass vat of high-molarity sulfuric acid, chemically breaking down the 'clean' cathode into a highly toxic aqueous solution.
    1. Electrolytic dissolution
  2. Preconcentration (applying a negative potential to accumulate trace metal ions onto a working electrode) — A custom working electrode, physically cast in the topographical shape of the Kasulo neighborhood, is submerged. A negative voltage draws the dissolved cobalt out of the battery solution, electroplating it back into the precise geometry of its origin landscape.
    2. Preconcentration and Deposition
  3. Anodic stripping voltammetry (sweeping the potential positively to re-oxidize the metals, measuring the current peaks to identify trace impurities) — The voltage is reversed, rapidly stripping the cobalt off the topographical landscape. The resulting current spikes, triggered by the unique copper/uranium trace impurities, drive a heavy mechanical impact hammer that pounds the surrounding earth.
    3. Anodic Stripping
  4. Peak integration (calculating the area under the current-voltage curve to determine exact molar concentration) — The integrated area of the stripping curve is calculated by a microcontroller, which then dictates the exact volume of raw red Kolwezi earth dumped by an automated hopper onto the corroded battery chassis, permanently burying it.
    4. Integration of the Voltammetric Peak

curatorial qa (machine verdict, unedited)

SCORE 3/5 after 2 attempt(s)
READS: The acid leaching of the EV battery pack and the blue plumes of cobalt solution dispersing over the topographical copper electrode read clearly.
FAILS: The crucial third phase of anodic stripping voltammetry is absent; the pluming looks more like passive ink diffusion than electrochemical deposition and re-oxidation.
