Secondary Cells TRIZ Cases

Integrated cooling channels in a press-hardened EV battery tray improve heat transfer and crash resistance while reducing parts and cost.

A magnet-held piston vent quickly releases abnormal battery pack pressure, then re-seals the pack and supports venting failure detection.

A dual-active-material cathode and film-forming electrolyte additives improve Li-ion lithiation stability, energy density, and cycle life.

A two-part ceramic-filled curable TIM balances heat conduction, flexibility, and dispenseability for EV battery thermal management.

Carboxylate ester and norbornene anhydride additives cut interfacial impedance and electrolyte decomposition for faster charging and stable high-temperature cycling.

A deformable Belleville end plate keeps battery cell stack pressure stable despite tolerances and swelling, improving lifetime reliability and safety.

Grinding multilobal HDPE particles into micropowder keeps particle size below 15 microns while lowering bulk density for easier incorporation and dispersion.

Controlling anode bulk density ratio and polymer coating helps roll-pressed lithium-ion electrodes resist cracks while enabling thinner, stronger electrodes.

An embossed fluid-filled separator pad compensates battery cell swelling and blocks thermal propagation while reducing parts, weight, and assembly effort.

A two-space discharge housing redirects runaway gases and collects particles to limit flame exposure and keep the vent path stable.

A supported fire-extinguishing member releases agent through cell vents to improve distribution uniformity and limit fire spread in battery packs.

Laminated precursor films create thin battery separators that resist wrinkling during coating while improving thickness uniformity and adhesion.

Controlled carbon black aggregate shapes with carbon nanotubes cut battery internal resistance and improve discharge rate and cycle life.

A cooling unit fixed to the busbar assembly sits between battery cells to improve heat removal, energy density, and assembly efficiency.

Protrusion-backed heat exchange walls expand cooling area and strength, helping battery cells stay cooler during high-rate charging.

A dual conductive-agent network preserves electrical bridging in titanium-oxide electrodes, limiting resistance growth during cycling.

Guide plates confine the liquid-swellable body so swelling opens the valve cover without deforming drain grooves or blocking battery pack drainage.

A reinforcing beam under the lower plate strengthens battery box opening areas while preserving the lightweight flow-passage structure.

Nb in a Ni-rich layered cathode plus W, B, or Al surface additives suppresses low-temperature resistance while reducing cobalt use.

A layered cathode pairs spinel, ternary, and phosphate materials with controlled particle sizes to improve packing density and cycling stability.

Integrated coolant channels in a cast front member cool the HV distribution box and busbar to support fast charging, performance, and safety.

A thin partition plate with bonding layers creates independent sealed battery cavities, cutting seal-edge thickness and folding stress while preserving energy density.

A polyether-acid additive suppresses slurry stringiness at the coating end point, improving electrode reliability without vibration equipment.
