THE ZSMC BATTERY ARCHITECTURE / Architecture

Three material systems, one stability problem.

The architecture consists of a scaffolded anode, a dual-active cathode, and a buffered gel electrolyte tuned for the electrode pair.

Anode

Zn-SnO2

Zinc is the primary electroactive material. SnO2 is included as a current-distribution modifier and nucleation scaffold intended to reduce localized zinc growth.

Primary role: capacity contribution from zinc.

Stability role: surface-energy and current-density homogenization.

Design concern: passivation and hydrogen evolution under aqueous conditions.

Cathode

MnO2-CuO

MnO2 provides the primary plateau. CuO is modeled as a secondary redox-active phase that can reduce resistance and contribute a secondary plateau near lower cell voltage.

Primary role: MnO2 capacity delivery.

Secondary role: CuO plateau and cathode profile smoothing.

Design concern: CuO accessibility decreases at higher C-rates.

Electrolyte

Quasi-solid gel

The electrolyte is treated as part of the architecture, not a commodity fluid. The formulation targets ion mobility, buffering, mechanical stability, and low-temperature support.

Target pH range: mildly acidic and buffered.

Stability role: gel matrix and glycerol support.

Design concern: dehydration, cracking, and resistance growth.
