Negative Electrodes TRIZ Cases
- Porous Silicon Anode Skeleton for Lithium Ion Battery
A porous silicon anode material with a main skeleton and branches accommodates volumetric expansion during lithium intercalation to prevent pulverization.
- Potassium Ion Compression Layer for Silicon Anode Swelling
Potassium ions displace sodium ions to form a compression layer that counters tensile stress from silicon swelling, preventing cracking and capacity loss.
- Silicon Negative Electrode Material with Glassy Matrix for Battery Cycle Life
A silicon negative electrode material uses a low-melting point inorganic oxide to fill voids within the particle agglomerate structure.
- Lithium Cathode Additives for Silicon Anode Capacity Retention
Cathode lithiation agents supply sacrificial lithium to build stable SEI layers, reducing irreversible consumption and preserving capacity during cycling.
- Crosslinked Binder for All-Solid-State Battery Stability
A crosslinked binder with carbonyl and amino groups maintains electrode physical properties during cycling.
- Silicon-Carbon Composite Negative Electrode for Lithium Batteries
A silicon-carbon composite negative electrode incorporates magnesium to enhance electrical conductivity.
