Non-Aqueous Electrolyte Accumulators TRIZ Cases

Embossed or wrinkled swelling tape controls air traps in a jelly-roll electrode assembly, improving case contact without increasing outer diameter.

Covalently bound phosphorus flame retardants in cellulose separators improve thermal stability and lower thermal runaway risk without raising electrolyte viscosity.

Center-pressing spacers balance cell expansion in rectangular battery packs to reduce electrolyte leakage and preserve high-rate performance.

Copper-templated nanowires are hydrothermally formed, then leached at room temperature to stabilize pure ζ-V2O5 for Mg-ion cathodes.

A protrusion-guided pressing ring increases terminal-post torsional strength, prevents lower plastic cutting, and simplifies stamping.

Separated top cap assemblies and a movable insulator vent gas and relieve stress in cylindrical batteries to limit deformation and thermal runaway.

Flame retardants bonded into cellulose battery separators improve thermal stability and lower thermal runaway risk without harming electrolyte performance.

Threshold-based battery control limits grid charge and discharge participation when electrolyte salt unevenness signals high-rate deterioration.

A rock-salt composite sulfide cathode lowers magnesium-ion diffusion barriers, enabling reversible cycling and higher capacity in magnesium batteries.
