Anode fundamentals01
7 min · Updated 2026-07-17A silicon–carbon composite is an anode active material that combines silicon with a carbon structure to raise capacity while improving electronic contact and managing some of silicon’s dimensional change. The carbon may form a matrix, coating, porous host or secondary-particle architecture, but the finished electrode still depends on binder, conductive additive, graphite ratio, porosity, electrolyte and formation.

7 min · Updated 2026-07-09A garnet solid electrolyte is an oxide ceramic whose crystal structure provides pathways for lithium-ion motion. The best-known battery example is the LLZO family, based on lithium lanthanum zirconium oxide. Garnet electrolytes are studied because they combine oxide chemistry, ceramic mechanical behavior and the possibility of lithium-metal interfaces, but useful performance depends on phase, dopant, density, grain boundaries and surface preparation.

7 min · Updated 2026-07-04Lithium sulfide is an inorganic lithium-and-sulfur compound used as a starting material in many sulfide solid-electrolyte synthesis routes. It supplies lithium and sulfur to systems such as Li2S–P2S5 and related compositions. Its usefulness depends on more than a purity percentage: impurity profile, moisture history, particle form, packaging and the downstream mixing or heat-treatment route can all affect the electrolyte produced from it.
