Sodium metal anode
A sodium metal anode is a battery negative electrode of metallic sodium with 1,166 mAh/g capacity and a low redox potential, central to sodium-metal batteries.
Sodium titanate cathode
Sodium titanate cathode is a term sometimes applied to sodium titanate materials, chiefly layered Na₂Ti₃O₇, used as anodes in sodium-ion batteries at about 0.3 V.
Sodium-ion battery anode
The sodium-ion battery anode is the negative electrode of a sodium-ion battery, storing sodium ions during charging; hard carbon is the standard material, with alloying alternatives like antimony and phosphorus.
Soft carbon
Soft carbon, or graphitizable carbon, is a disordered carbon that converts to graphite when heated above 2500 °C, used as an anode in sodium-ion batteries and as a graphite precursor.
Synthetic graphite
Synthetic graphite, also called artificial graphite, is graphite made by heating petroleum coke and coal tar pitch to about 3000 °C, a key lithium-ion battery anode material.
Tin oxide anode
A tin oxide anode is a battery negative electrode based on tin dioxide that stores lithium and sodium, with a theoretical capacity up to 1494 mAh g⁻¹, far above graphite's 372.
Titanium dioxide anode
A titanium dioxide anode is a battery electrode where titanium dioxide (TiO₂) stores lithium or sodium ions, offering safer, longer-lived operation than graphite at about 1.5 to 1.8 V.
Tokai Carbon
Tokai Carbon (東海カーボン) is a Japanese carbon products manufacturer headquartered in Tokyo. Founded in 1918 to make graphite electrodes for steelmaking, it now also produces lithium-ion battery anode materials.
Zero-strain anode
A zero-strain anode is a battery anode material whose crystal volume changes by less than 1% during lithium insertion and removal; lithium titanate (Li₄Ti₅O₁₂) is the archetype.
Zinc anode
A zinc anode is the negative electrode of a battery in which metallic zinc is oxidized during discharge, used since Volta's early-1800s piles in zinc-carbon, alkaline, zinc-nickel, zinc-air, and zinc-ion batteries.
