Graphite TRIZ Cases
- Spheronized Graphite Anode Material With Lower Internal Porosity
Mixing fine and coarse scaly graphite before spheronization fills internal pores after coating, improving anode stability and high-temperature storage.
- Carbon-Coated Spherical Graphite Anode With Pre-Densified Particles
Cold isostatic pressing before carbon coating densifies spherical graphite, limiting pore-driven swelling and high-temperature degradation.
- Surface-Modified Graphite Conductive Additives for Oxidative Stability
Surface-modified graphite with controlled pH and density resists oxidation while maintaining conductivity in batteries and fuel cells.
- Laser-Treated Graphite Bipolar Plates for Stable Hydrophilic Surfaces
Pulsed laser treatment makes graphite bipolar plate surfaces durably hydrophilic while avoiding coatings that raise electrical contact resistance.
- Graphite Anode Composite Coating for High-Power Li-Ion Batteries
A dual-layer graphite microcrystal and amorphous carbon coating boosts anode capacity, first-cycle efficiency, and power at low cost.
- Negative Electrode Active Material for Low-Swelling Battery Cycling
A high-viscosity additive strengthens secondary particles to limit crushing, reduce thickness swelling, and preserve lithium-ion battery cycle life.
- Silicon-Iron Anode Material With Carbon Shells for Volume Stability
A graphitized silicon-iron and hard carbon composite uses acid washing and carbon shells to limit swelling, lower resistance, and extend battery life.
- Graphite Anode Particle Hierarchy for High-Rate Lithium Batteries
Hierarchical natural graphite particles with an amorphous carbon coating improve high-rate charging and cycling while limiting battery deterioration.
- Dry Microgranulation of Battery Particles for Narrow Size Distribution
High-shear mechanofusion forms uniform, spherical, dense battery particles without solvents, reducing waste and tightening size distribution.
- Negative Electrode Composite for Capacity and Cycle-Life Balance
A carbon-coated transition metal oxide core blended with crystalline carbon buffers expansion and preserves lithium capacity over cycling.
- Graphite Anode Particle Mixing for Battery Cycle Endurance
Smaller graphite particles fill gaps between larger anode particles to preserve conductive paths and improve non-aqueous battery capacity retention.
- Carbon-Coated Negative Electrode for Stable High-Capacity Cycling
A voided transition metal oxide core with amorphous carbon coating and crystalline carbon balances initial capacity with cycle-life stability.
