Single-crystal cathode material
A single-crystal cathode material is a lithium-ion battery cathode in which each active particle is one continuous crystal, avoiding grain-boundary cracking for longer cycle life and stability.
Single-crystal lithium iron phosphate cathodes
Single-crystal lithium iron phosphate (LiFePO₄, LFP) cathodes are lithium-ion battery cathode materials in which each particle is one continuous olivine crystal, grown as nanoscale plates or rods.
Solid-state composite cathode
A solid-state composite cathode is the positive electrode of an all-solid-state battery, a solid mix of active material, solid electrolyte, carbon, and binder that must conduct ions and electrons.
Sulfurized polyacrylonitrile
Sulfurized polyacrylonitrile (SPAN, also written S@pPAN or S@PAN) is a composite cathode material for lithium–sulfur batteries, made by co-heating sulfur with polyacrylonitrile and first reported in July 2002 by Jiulin Wang and colleagues.
Surface rocksalt reconstruction in Ni-rich cathodes
Surface rocksalt reconstruction is the degradation of Ni-rich layered lithium-ion cathode surfaces, which transform from layered to spinel to inert rock-salt phases, accelerated by high nickel content, state of charge, and temperature.
Thacker Pass
Thacker Pass is a lithium mine under construction in Humboldt County, Nevada, owned by Lithium Americas and General Motors and holding one of the world's largest lithium reserves.
Titanium disulfide
Titanium disulfide (TiS₂) is a layered solid used as the cathode of the first rechargeable lithium battery, developed by M. Stanley Whittingham at Exxon in the 1970s.
Ultra-high-nickel cathodes
Ultra-high-nickel cathodes are layered lithium-ion battery cathode materials, such as NCM90 and NCM95, in which nickel accounts for at least 90 mol% of transition metals, delivering high capacity while reducing cobalt use.
