Title: Revisiting the Corrosion of the Aluminum Current Collector in Lithium-Ion Batteries

Abstract

The corrosion of aluminum current collectors and the oxidation of solvents at a relatively high potential have been widely investigated with an aim to stabilize the electrochemical performance of lithium-ion batteries using such components. The corrosion behavior of aluminum current collectors was revisited using a home-build high-precision electrochemical measurement system, and the impact of electrolyte components and the surface protection layer on aluminum foil was systematically studied. The electrochemical results showed that the corrosion of aluminum foil was triggered by the electrochemical oxidation of solvent molecules, like ethylene carbonate, at a relative high potential. The organic radical cations generated from the electrochemical oxidation are energetically unstable, and readily undergo a deprotonation reaction that generates protons and promote the dissolution of Al 3+ from the aluminum foil. Finally, this new reaction mechanism can also shed light on the dissolution of transitional metal at high potentials.

  • With significant improvements in electrical energy storage, researchers could change the way energy is generated and used. One emerging approach is to change the cation that shuttles charge from lithium to calcium. Calcium cations, roughly the same size as Na+, have many attributes that make them a desirable charge carrier for energy storage applications, including deposition voltage and a porous passivation layer. However, system level issues, such as corrosion, have yet to be investigated. Corrosion of the current collectors must be considered whenever you change the electrolyte and we show that this is particularly true for calcium based systems. Reversiblemore » charge/discharge behavior that is due to corrosion can be seen with stainless steel in electrolytes containing calcium salts. This reversible behavior is similar to what might be expected from materials that are intercalating Ca, making the interpretation of electrochemical data challenging. We have found that this corrosion reaction requires either carbon black and/or a transition metal oxide to catalyze the reaction, making it more difficult to detect. Unlike stainless steel, Graphite foil electrodes do not show high voltage reactions and can be used as a tool for testing Ca-ion cathode materials, although some reactions at low potentials have been observed.« less

  • The corrosion behavior of aluminum, a candidate material for the current collectors of the positive electrodes of lithium-polymer batteries, in contact with a lithium polymer electrolyte was examined in both batteries and three-electrode electrochemical cells. The results indicate aluminum is resistant to uniform corrosion in the polymer electrolyte: poly(ethylene oxide)-LiN(CF{sub 3}SO{sub 2}){sub 2} but can be susceptible to pitting corrosion. Localized pitting corrosion occurs on the aluminum current collector during overcharging of the battery. Pitting corrosion only occurred in the electrochemical cells when the aluminum electrode was anodically polarized to potentials that were considerably greater than those that resulted inmore » pitting corrosion in batteries. The greater susceptibility of the aluminum current collectors of batteries to pitting corrosion is attributed to inhomogeneous current flow through the current collector. This results in local breakdown of the passive film on aluminum at sites of locally high current density. The inhomogeneous current density that flows through the aluminum/cathode interface is caused by the presence of discrete paths through the cathode with low electrical resistance. In an effort to improve the localized corrosion behavior of aluminum electrodes, it was found that surfaces impregnated by ion implantation with {approximately}20 atom % tungsten exhibited enhanced resistance to pitting corrosion in poly(ethylene oxide)-LiN(CF{sub 3}SO{sub 2}){sub 2}.« less
