Electrode Thermal Treatment TRIZ Cases
- Oxygen-Scavenging Cathode Coating for High-Nickel Li-Ion Stability
A polymer coating with an oxygen scavenger removes oxygen at high-nickel cathodes, limiting side reactions and preserving capacity retention.
- 3D Positive Electrode Structure for Uniform Li-Ion Battery Current
Spaced positive electrode plates and a separator metal layer even out ion and electron flow to improve rate capability and battery life.
- Amorphous Silicon-Carbon Composite to Limit Anode Volume Expansion
Pyrolysis forms an amorphous silicon-carbon composite that curbs anode swelling and fragmentation while improving conductivity and cycle life.
- Layered Negative Electrode Structure for Fast-Charging Secondary Batteries
A two-layer negative electrode balances energy density and fast charging by pairing low-slope and high-slope active materials.
