Alkaline Accumulator Electrodes TRIZ Cases

Specific wetting and antifoam additives stabilize alkaline zinc battery electrolytes, limiting foam, mass loss, and anode degradation over cycling.

Using recycled-rich aluminium with a controlled CO2e-to-yield-strength ratio cuts battery housing emissions while preserving formability and strength.

A higher electrolyte-to-capacity ratio helps α-nickel hydroxide positive electrodes raise utilization while maintaining capacity density and stability.

Fine zinc oxide or hydroxide in the anode and electrolyte limits passivation and bridging, extending alkaline cell runtime under high drain.

Wetting and antifoam additives in alkaline zinc electrolytes suppress dendrites, stabilize membranes, and extend cycle life.

A phase-controlled nickelate cathode improves alkaline cell shelf life and discharge capacity by stabilizing high-valent nickel in aqueous electrolyte.

Electrolyte reservoirs inside alkaline electrodes expand reaction area for high-rate discharge without adding separator material or sacrificing active volume.

Homogeneous aluminum doping and spherical β-nickel hydroxide particles raise packing density and charge capacity for battery electrodes.

Ammonia-mediated precipitation keeps aluminum uniformly in β-nickel hydroxide while preserving spherical particles, packing density, and battery precursor performance.

A fused-ring cyclic additive adsorbs on zinc to curb hydrogen gas, lower internal pressure, and reduce leakage during storage.

Acid-treated non-stoichiometric metal oxide cathodes raise alkaline battery energy density while stabilizing charge balance and shelf life.

Acid-treated non-stoichiometric cathodes raise transition-metal oxidation state to improve alkaline battery energy density and shelf life.

β-CoOOH-coated nickel hydroxide, W/Zn/Y additives, and a fluorinated separator curb resistance rise during high-temperature overcharge.

A zinc phosphate layer isolates the zinc anode from aqueous electrolyte, suppressing side reactions and guiding uniform dendrite growth.

A mixed phase hydrogen storage alloy electrode uses a nickel-rich surface layer to reduce diffusion resistance.

A secondary electrochemical cell uses a composite negative electrode combining carbon-based storage material and iron to store electrical charge.

High speed rotation and controlled oxygen atmosphere reduce slippage to produce smaller zinc particles for alkaline batteries.
