Li-Accumulators TRIZ Cases
- Electrolytic solution and non-aqueous electrolytic solution secondary battery
A carboxylic acid ester electrolyte with tightly limited hydroxy or ether compounds stabilizes the negative electrode and preserves high-current discharge capacity.
- Imidazolium Polyether Composition for High-Pressure CO2 Absorption
Imidazolium side chains and a selected counter anion raise CO2 absorbency in polyether ionic compositions under ordinary and high pressure.
- Fluorinated Electrolyte Composition for Low-Resistance Secondary Batteries
Fluorinated alkali metal alkoxides and ethers in the electrolyte help curb resistance rise, metal precipitation, and durability loss in secondary batteries.
- Polycarbonate Resin Composition for Carbonate-Solvent Electrolytes
A tailored polycarbonate resin dissolves in carbonate solvents to form low-toxicity coating films and conductive electrolytes for batteries.
- Electrolyte Additives for Li-Ion Capacity Retention Across Temperatures
A dual-additive electrolyte forms a low-impedance cathode passivation layer while suppressing oxidative decomposition to retain capacity at low and high temperatures.
- Sultone Electrolyte Additive for Stable SEI at High Temperature
A sultone-based electrolyte additive forms a low-resistance, stable SEI that limits high-temperature degradation and extends lithium battery life.
- Non-Aqueous Electrolyte Composition for Low-Temperature Battery Cycling
A vinylene carbonate and Formula I electrolyte balances dense SEI/CEI passivation with ion conduction to improve low-temperature discharge and cycling.
- Electrolyte Composition for Low-Temp Discharge and Oxidation Stability
A dual-additive electrolyte forms a protective cathode interface and suppresses oxidation, improving low-temp discharge and high-temp cycling.
- Non-Aqueous Electrolyte Additives for Stable Lithium Battery Cathodes
A sulfonyl phosphorus additive suppresses cathode-electrolyte side reactions while lowering resistance to improve cycle life and high-temperature stability.
- Non-Aqueous Electrolyte Additives for Stable Low-Impedance SEI Films
Cyclic sulfate and cyclic carbonate additives build a stable, elastic SEI film that lowers impedance while protecting lithium-ion battery electrodes.
- Nonaqueous Electrolyte With Oxide Particles for Li-Ion Charge Efficiency
Insoluble oxide nanoparticles tune Li-ion solvation while preserving electrolyte fluidity, improving charge-discharge efficiency and cycle life.
- Fluorinated Aromatic Electrolyte for Safer Lithium Secondary Batteries
A fluorinated aromatic and ether electrolyte suppresses side reactions, lowers flammability, and maintains conductivity in lithium secondary batteries.
- Non-Aqueous Lithium Battery Electrolyte for High-Temperature SEI Stability
A fluorinated propargyl additive forms a robust SEI that resists high-temperature decomposition, metal ion elution, and rising cell resistance.
