Alloying anode
An alloying anode is a battery negative electrode of metals like silicon and tin that stores charge by forming alloys with lithium or sodium ions.
Artificial solid electrolyte interphase
An artificial solid electrolyte interphase (Art-SEI) is a protective layer deliberately applied to a battery anode to replace the natural interphase, mainly for lithium metal anodes, where it suppresses dendrites and extends cycle life.
Biomass-derived hard carbon
Biomass-derived hard carbon is a non-graphitizable carbon anode material for sodium-ion batteries, made by pyrolyzing renewable waste precursors such as lignin, cellulose, nutshells, and fruit peels.
BTR New Material Group
BTR New Material Group Co., Ltd. is a Chinese manufacturer of anode and cathode materials for lithium-ion batteries, headquartered in Shenzhen and the world's leading anode producer since 2010.
Co-intercalation in graphite
Co-intercalation in graphite is a battery electrode process in which metal ions enter graphite together with their solvent molecules, enabling graphite anodes for sodium-ion batteries.
Conversion–alloy mechanism
The conversion–alloy mechanism is a sodium-storage reaction in certain sodium-ion battery anodes, where a metal compound first converts to metal and a sodium compound, then alloys with more sodium.
Graphene anode
A graphene anode is a lithium-ion battery negative electrode in which graphene serves as the active material, investigated since 2008 as a higher-capacity alternative to graphite.
Graphite anode
The graphite anode is the negative electrode of a lithium-ion battery, storing lithium between layered carbon sheets; it has been the commercial standard since the early 1990s.
Hard carbon
Hard carbon is a non-graphitizable form of carbon, made by carbonizing biomass or resin at 1000–1600 °C, and is the dominant anode material for sodium-ion batteries.
Hard carbon anode
A hard carbon anode is a battery negative electrode made from hard carbon, a disordered amorphous carbon that cannot be converted into graphite even above 3000 °C, and the leading anode for sodium-ion batteries.
Hard carbon anodes for sodium-ion batteries
Hard carbon anodes for sodium-ion batteries are disordered carbon materials that store sodium through adsorption, intercalation, and pore filling, since graphite stores little sodium, making hard carbon the leading anode candidate.
Lignin-based hard carbon anode
A lignin-based hard carbon anode is a sodium-ion battery anode made by carbonizing lignin, an abundant papermaking byproduct, into hard carbon; Stora Enso's Lignode is the leading commercial example.
Lithiated graphite anode
A lithiated graphite anode is a lithium-ion battery negative electrode pre-loaded with lithium ions up to LiC6, compensating the lithium irreversibly consumed when the SEI forms.
Lithiated silicon oxide
Lithiated silicon oxide is silicon suboxide (SiOx) battery anode material after reacting with lithium, forming lithium oxide and silicate phases that buffer silicon's volume change.
Lithium metal anode
A lithium metal anode is a battery negative electrode made of metallic lithium, offering the highest theoretical capacity of any anode but held back by dendrite growth.
Lithium titanate
Lithium titanate (Li₄Ti₅O₁₂, LTO) is a spinel oxide used as the anode in lithium-ion batteries known for safety, fast charging, and very long cycle life.
Lithium-ion battery anode
The lithium-ion battery anode is the negative electrode that stores lithium ions during charging and releases them on discharge; commercial cells almost always use graphite.
Natural graphite
Natural graphite is graphite mined from metamorphic rock deposits rather than synthesized from hydrocarbons. It dominates lithium-ion battery anodes, offering low cost, abundance, and high theoretical capacity.
Niobium-based oxide anode
A niobium-based oxide anode is a lithium-ion battery anode material using niobium oxides, alone or with titanium or tungsten, that charges fast without lithium dendrites or SEI growth.
Nippon Carbon
Nippon Carbon is a Japanese manufacturer of carbon products, founded in 1915 and headquartered in Tokyo, known for graphite electrodes, carbon fibers, and lithium-ion battery anode materials.
