Lithium-ion (Li-ion) refers to a family of rechargeable battery chemistries that all operate by shuttling lithium ions between a positive electrode (cathode) and a negative electrode (anode) through an electrolyte. Since their commercial introduction in the early 1990s by Sony, Li-ion batteries have revolutionized portable electronics and enabled the rise of electric vehicles due to their high energy density, lack of memory effect, and excellent cycle life. Common components of a Li-ion cell include: an anode usually made of graphite, a cathode made of a lithium metal oxide or phosphate (such as NMC, NCA, LFP, etc.), and an electrolyte composed of a lithium salt in an organic solvent mixture. Li-ion cells come in cylindrical, prismatic and pouch form factors. Proper management is required to avoid overcharging or deep discharge to ensure cell safety and longevity.
Dryve’s work is centered around Li-ion technology. They are involved in researching novel cathode materials (like high-nickel or cobalt-free compositions) and electrolyte additives for enhanced performance.
