Small-Sized Cells Cases/Jackets TRIZ Cases
- Cylindrical Battery Cell Contacts to Eliminate Housing-Wall Current Path
Separate insulated terminals on one end face avoid current flow through the housing wall, cutting resistance and short-circuit risk.
- Battery Module Bus Bar Welding for Stable Al-Cu Tab Joints
Controlled weld bead geometry stabilizes laser joining of aluminum tabs to copper bus bars, improving strength, resistance, and durability.
- Multi-Cell-Stack Battery Module Housing for High-Power Connection
Integrated housing links adjacent cell stacks to raise battery power while simplifying electrical connection, cooling, and assembly.
- Battery Cell Reconditioning via Laser Bus Bar Separation
Laser detachment of bus bar contacts enables battery cell replacement and fast reconditioning without damaging reusable cells.
- Recessed Battery Connector Layout for Scratch-Resistant Coupling
A recessed connector and guide-face battery casing reduces scratches during handling while helping electrode terminals couple securely.
- Battery Module Flex Circuit With Redundant Traces for Thermal Runaway
Redundant flex-circuit traces replace complex battery module wiring and preserve busbar voltage monitoring during thermal runaway damage.
- Removable Battery Pack Locking for Stable Carrier Vehicle Swaps
A detachable battery handle and elastic locking piece secure carrier vehicle battery swaps while enabling flexible off-board charging.
- Eddy Current Battery Tab Inspection for Fast Weld Quality Screening
Eddy current sensing checks battery tab-lead weld integrity through impedance analysis, enabling fast non-destructive inspection on production lines.
- Jelly-Roll Battery Electrode Tabs for Stable Surface Welding
Angled notches create trapezoidal electrode tabs that stay flat against current collectors, improving weld uniformity and reducing short-circuit risk.
- Secondary Battery Electrode Composition for High-Load Cyclability
Fluorine and nitrogen compounds in both electrode layers stabilize films and suppress decomposition, improving high-load battery cycling.
- Parallel Electrode Assemblies With Intermediate Tabs for Battery Cells
Intermediate tabs placed between parallel electrode assemblies shorten current paths, reducing resistance and heat in high-energy-density battery cells.
- Laminate Battery Module Venting to Limit Overheat Spread
Mold resin isolates laminate batteries while exposed exhaust parts preserve gas venting paths, limiting heat spread and damage expansion.
- Battery Cell Tab Welding Structure to Prevent Cracking
Overlapping pre-weld and main weld regions strengthen the electrode lead joint while reducing tab cracking and disconnection in battery cells.
- Waterproof Battery Pack Terminal Structure for Vibration-Stable Assembly
A sealed terminal structure uses waterproof members and threaded fastening to block water ingress and keep battery pack connections stable under vibration.
- Flame-Retardant Electrode Coating for Battery Short-Circuit Suppression
A flame-retardant coating between coated and uncoated electrode regions blocks direct contact and absorbs heat during battery faults.
- Battery Module Terminal Cover Structure for Nut Fixation and Debris Blocking
A frame cover stabilizes the terminal nut during strong bolt tightening while blocking friction debris from entering the battery module.
- Cross-Beam Battery Pack Layout for Module-Free Cell Integration
Cross beams divide the pack into cell chambers, enabling module-free cell mounting that raises space utilization, energy density, and assembly efficiency.
