Abstract:
The world of long-term-high-density energy storage systems is dominated by the lithium-ion (Li-ion) battery. However, associated setbacks with the Li ion industry such as safety, geopolitical concerns, and rising costs have spearheaded research into investigating alternative approaches to the Li-ion batteries. A promising alternative to the Li-ion battery is the zinc manganese oxide (Zn||MnO2) battery due to its high energy density and much safer chemistry. However, a step towards commercialization of the Zn||MnO2 requires a deep dive into the failure mechanisms native to such cells. These fai

Abstract:
Zn-MnO2 batteries with mildly acidic electrolytes are a promising chemistry for large scale storage thanks to their remarkable energy density, low cost, and high safety. This is mainly obtained thanks to the high capacity of the Zn metal anode, and the nonflammable character of the aqueous electrolyte. MnO2 is one of the most common cathode of choice, not only for being Earth-abundant, but also because it can undergo a two-electron mechanism, which is however complex and still not fully understood. There is currently agreement in considering for discharge a MnO2 dissolution, leading to soluble

Abstract:
Manganese dioxide (MnO2) with different crystal structures has been widely investigated as the cathode material for Zn-ion batteries, among which spinel λ-MnO2 is yet rarely reported because Zn-ion intercalation in spinel lattice is speculated to be limited by the narrow three-dimensional tunnels. In this work, we demonstrate that Zn-ion insertion in spinel lattice can be enhanced by reducing particle size and elucidate an intriguing electrochemical reaction mechanism dependent on particle size. Specifically, λ-MnO2 nanoparticles (NPs, ~80 nm) deliver a high capacity of 250 mAh/g at 20 mA/g du

Achieving commercially acceptable Zn-MnO2 rechargeable batteries depends on the reversibility of active zinc and manganese materials, and avoiding side reactions during the second electron reaction of MnO2. Typically, liquid electrolytes such as potassium hydroxide (KOH) are used for Zn-MnO2 rechargeable batteries. However, it is known that using liquid electrolytes causes the formation of electrochemically inactive materials, such as precipitation Mn3O4 or ZnMn2O4 resulting from the uncontrollable reaction of Mn3+ dissolved species with zincate ions.

Battery discharge leads to a decrease in the zinc particle sizes, revealing a layer-by-layer dissolving behavior. During charging, the particles grow again to almost their initial size and shape.
