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.
NOVONIX’s work is centered around Li-ion technology. They are involved in researching nearly every aspect: novel anode materials (like silicon composites), novel cathode materials (like high-nickel or cobalt-free compositions), electrolyte additives for enhanced performance, and even alternatives like lithium metal or anode-free designs for next-gen Li-ion cells. NOVONIX provides advanced testing tools such as the UHPC equipment, to precisely measure Li-ion cell efficiency and degradation, which helps researchers and manufacturers improve their designs. NOVONIX also stays on the cutting edge of how Li-ion technology is evolving. Essentially, if it concerns lithium-ion batteries—be it making them charge faster, last longer, or store more energy—NOVONIX is working on it through both providing paid Services to customers and internal R&D, pushing the boundaries of what Li-ion can do.
