TECHNICAL FIELD

This disclosure relates to secondary electrodes and batteries containing the same.

BACKGROUND

A secondary cell may include an anode and cathode.

Chemical reactions of a secondary cell are reversible. When the cell is being charged for example, the anode may become positive and the cathode may become negative. When the cell is being discharged, it behaves like a primary cell.

SUMMARY

An electrochemical component has a green secondary electrode including a conductive substrate and electrochemically active materials and material additives in direct contact with the conductive substrate, and a combination of Vinyl Acetate-Ethylene (VAE) and methylcellulose-based additives, such as CarboxyMethylCellulose (CMC) or HydroxyPropyl MethylCellulose (HPMC), binding the conductive substrate, electrochemically active materials, and material additives together. Specifically, electrodes for aqueous-based batteries, such as the lithium-zinc, nickel-zinc (Ni—Zn), silver-zinc, zinc-air, and zinc-ion batteries, made with these binder combinations are mechanically robust and exhibit high electrochemical performance.
