On comparing the reactivity of silver and lead, it is observed that the two ionic species, Ag+ (aq) and Pb2+ (aq), show a difference in their redox reactivity towards copper: the silver ion undergoes spontaneous reduction, while the lead ion does not. This relative redox activity can be easily quantified in electrochemical cells by a property called cell potential. This property is commonly known as cell voltage in electrochemistry, and it is a measure of the energy which accompanies the charge...

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

Electrodeposition

Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

Area of Science:

  • Electrochemistry
  • Materials Science
  • Energy Storage

Background:

  • Zinc-ion batteries (ZIBs) offer safe and cost-effective energy storage due to their zinc metal anode and aqueous electrolytes.
  • However, ZIB performance is limited by surface side reactions and dendrite formation on the anode, reducing lifespan and efficiency.

Purpose of the Study:

  • To investigate the efficacy of l-ascorbic acid sodium (LAA) as a bifunctional electrolyte additive in zinc sulfate (ZSO) electrolytes for ZIBs.
  • To mitigate anode side reactions and dendrite growth, thereby improving the electrochemical performance and stability of ZIBs.

Main Methods:

  • Addition of l-ascorbic acid sodium (LAA) to a zinc sulfate (ZSO) electrolyte.
  • Surface analysis of the zinc anode to observe passivation layer formation.
  • Electrochemical testing of Zn/Zn symmetric batteries and Zn/Ti cells to evaluate cycle life and Coulombic efficiency.
  • Testing in Zn/MnO2 full batteries and pouch cells to confirm additive effectiveness.

Main Results:

  • LAA forms a H2O-resistive passivation layer on the Zn anode, isolating it from corrosion and promoting uniform Zn2+ ion deposition.
  • LAA modifies the solvation structure of Zn2+ ions, reducing coordinated water molecules and suppressing side reactions.
  • Zn/Zn symmetric batteries with ZSO + LAA electrolyte achieved 1200 h cycle life at 1 mA cm-2.
  • Zn/Ti batteries demonstrated ultrahigh Coulombic efficiency (99.16%) at 1 mA cm-2, outperforming those with ZSO electrolyte alone.

Conclusions:

  • LAA acts as an effective bifunctional additive, enhancing ZIB performance by improving anode stability and ion transport.
  • The synergistic effects of LAA lead to significantly improved cycle life and Coulombic efficiency in ZIBs.
  • LAA demonstrates potential for practical application in ZIBs, as validated in full cells and pouch cells.
