Conversion-type cathode
A conversion-type cathode is a battery positive electrode that stores charge by breaking down and reforming its host compound, storing 2 to 3 lithium per metal instead of less than one.
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.
Core Lithium
Core Lithium Ltd is an Australian hard-rock lithium mining company that owns the Finniss Lithium Operation southwest of Darwin, restarted in 2026 after a 2024 suspension.
Covalent Lithium
Covalent Lithium is an Australian lithium producer, a 50:50 joint venture between Wesfarmers and Chile's SQM that operates the Mount Holland mine and a Kwinana refinery producing battery-grade lithium hydroxide.
Cyclic carbonate electrolytes
Cyclic carbonate electrolytes are lithium-ion battery electrolytes built on ethylene carbonate and propylene carbonate, whose ring structures dissolve salt and form the protective anode film.
Cylib
Cylib is a German lithium-ion battery recycling startup founded in 2022 in Aachen as a spin-off from RWTH Aachen University by Lilian Schwich, Paul Sabarny, and Gideon Schwich.
Dendrite penetration in solid electrolytes
Dendrite penetration in solid electrolytes is the growth of lithium metal filaments through the ceramic electrolyte of an all-solid-state battery, which short-circuits the cell and remains a leading obstacle to commercialization.
Dieffenbacher
Dieffenbacher, formally DIEFFENBACHER GmbH Maschinen- und Anlagenbau, is a German family-owned company in Eppingen, Baden-Württemberg, founded in 1873 by Jakob Dieffenbacher, which builds press systems and complete plants for wood-based panels, forming, recycling, and energy.
Direct cathode upcycling
Direct cathode upcycling is a battery-recycling approach that repairs and upgrades a spent lithium-ion cathode's chemistry while keeping its crystal structure, converting low-nickel into nickel-rich material.
Direct lithium extraction
Direct lithium extraction (DLE) is a family of chemical processes that extracts lithium from brines without solar evaporation, cutting brine-to-carbonate time from about a year to around a day.
Direct recycling
Direct recycling is a lithium-ion battery recycling method that recovers and regenerates cathode material intact, preserving its crystal structure and avoiding energy-intensive metal extraction and resynthesis.
Disordered rock salt
Disordered rock salt (DRX) is a class of lithium-ion battery cathode materials in which lithium and transition-metal cations randomly share one lattice, promising high cobalt-free capacity since the mid-2010s.
Dongdao New Energy (广东东岛新能源股份有限公司)
Dongdao New Energy (Guangdong Dongdao New Energy Co., Ltd., 广东东岛新能源股份有限公司) is a Chinese maker of lithium-ion battery anode materials, founded in 2011 in Zhanjiang, Guangdong.
Dry electrode processing
Dry electrode processing is a solvent-free method of making lithium-ion battery electrodes from dry powders instead of slurry coating, eliminating toxic solvents like NMP and cutting drying costs.
Ecobat
Ecobat is a battery recycling and resource recovery company headquartered in Dallas, Texas, that recycles lead-acid batteries and produces lead and lead alloys, and until 2026 also recycled lithium-ion batteries.
Electra Battery Materials
Electra Battery Materials Corporation, formerly First Cobalt Corp., is a Canadian company building North America's first battery-grade cobalt sulfate refinery at Temiskaming Shores, Ontario, with cobalt assets in Idaho.
Electrolyte additive
An electrolyte additive is a minor component, a few tenths of a percent to a few weight percent, dissolved in lithium-ion battery electrolytes to improve stability, cycle life, and safety.
Ether electrolytes for lithium–sulfur batteries
Ether electrolytes for lithium–sulfur batteries are liquid electrolytes built on ether solvents like DME and DOL, widely used because they dissolve polysulfides but suffer from the shuttle effect.
Fluorinated ether electrolyte
A fluorinated ether electrolyte is a battery electrolyte in which ether solvents carry carbon-bound fluorine, weakening lithium coordination and raising oxidation stability for lithium-metal, sodium-ion, and high-voltage cells.
Fluorine-free electrolyte
A fluorine-free electrolyte is a battery electrolyte in which no component contains fluorine, investigated to replace commercial LiPF6-based electrolytes over safety, environmental, and regulatory concerns.
Fulin Precision
Fulin Precision, formerly Mianyang Fulin Precision Machining, is a Chinese automotive-parts and lithium battery cathode-materials maker in Mianyang, Sichuan, founded in 1997 and listed on ChiNext since 2015.
Full concentration gradient cathode
The full concentration gradient (FCG) cathode is a lithium-ion battery cathode particle in which nickel decreases and manganese rises continuously from core to surface, combining high capacity with stability.
Ganfeng Lithium
Ganfeng Lithium, formally Ganfeng Lithium Group Co., Ltd. (赣锋锂业), is a Chinese lithium producer founded in March 2000 and headquartered in Jiangxi Province, spanning refining, batteries, and recycling for customers including Tesla and BMW.
Garnet solid electrolyte
A garnet solid electrolyte is a ceramic lithium-ion conductor of the garnet mineral structure, most prominently LLZO, first reported in 2007 and valued for combining high lithium-ion conductivity with stability against lithium metal.
Gel polymer electrolyte
A gel polymer electrolyte, also called a plasticized polymer electrolyte, is a quasi-solid battery electrolyte in which a polymer network traps liquid electrolyte, first reported in 1975.
Goulamina
Goulamina is a hard-rock lithium (spodumene) mine in southern Mali, about 150 kilometers south of Bamako, majority-owned by China's Ganfeng Lithium and inaugurated in 2024 as Mali's first lithium mine.
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.
Halide solid electrolytes
Halide solid electrolytes are lithium or sodium metal halides such as Li₃YCl₆ and Li₃InCl₆ that conduct ions at room temperature, developed as solid electrolytes for all-solid-state batteries.
Halide solid-state electrolyte
A halide solid-state electrolyte is a solid inorganic material, typically a lithium or sodium halide, that conducts alkali-metal ions in all-solid-state batteries instead of flammable liquid electrolytes.
