Silicon TRIZ Cases

Al-containing Si clathrate anodes suppress volume change during cycling, reducing restraint pressure variation and particle damage in lithium-ion batteries.

Non-metallic silicon-bonded compounds passivate wafer surfaces during cutting and cleaning to reduce damage, oxidation, and metal adsorption.

Pulsed gas flow and stirring create a highly uniform fluidized bed for silicon deposition in porous particles, improving anode cycling stability.

Single-bonded silicon treatment compounds form a passivation layer during wafer cutting and cleaning to reduce damage, residues, and cost.

Fine pores in silicon clathrate anode material absorb Li ions and limit charge-discharge swelling, improving battery durability.

Low-temperature oxidation forms a uniform SiOx layer on nano silicon, then graphite milling improves conductivity and cycle life.

Dual carbon coatings on doped silicon nanoparticles suppress lithiation swelling, improve charge transfer, and stabilize capacity retention.

Granulated graphite-coated silicon particles improve anode contact stability, avoid high-viscosity CNT slurries, and reduce cell swelling.

Fine voids in silicon clathrate anode particles absorb Li ions to limit charge-discharge swelling and improve battery durability.

A silicon oxide-metal alloy interlayer and carbon shell limit silicon swelling, improve conductivity, and support stable SEI formation.

Heat-treated nanosilicon, graphite, and amorphous carbon improve Li-ion anode capacity while limiting silicon expansion and cycle loss.

Thin carbon shells on nonaggregated silicon particles reduce expansion damage and capacity loss while preserving high silicon content in lithium-ion anodes.
