Chemistry
The 18650 designation refers only to the physical dimensions of the cell and does not specify its electrochemistry. Most 18650 cells are lithium-ion batteries and have been manufactured using several cathode chemistries, including lithium cobalt oxide (LCO),Electronic transport properties in lithium cobalt oxide battery electrode material studied in ion-gated transistor configuration manganese dioxide (LMO Lithium ion manganese oxide battery), lithium nickel manganese cobalt oxide (NMC),NMC Battery vs. LCO Battery: What’s the Difference? lithium nickel cobalt aluminum oxide (NCA),Fast–charging lithium–ion batteries: Review on enhancing lithium nickel cobalt aluminum oxide cathodes with additives and lithium iron phosphate (LFP Lithium iron phosphate battery). Different chemistries offer trade-offs between energy density, power output, cycle life, cost, and thermal stability.
NCA and NMC chemistries have been widely used in high-energy applications such as electric vehicles and power tools, while LFP cells are valued for their long cycle life and improved thermal stability.
By the early 2020s, manufacturers had also introduced sodium-ion cells in the 18650 form factor. In 2024, a potassium-ion battery in the 18650 format was announced, demonstrating that the form factor can accommodate emerging battery chemistries in addition to lithium-ion technologies.Group1 Group1 Unveils First Potassium-ion Battery in 18650 Format https://www.prnewswire.com/news-releases/group1-unveils-first-potassium-ion-battery-in-18650-format-302211876.html 2024-09-05 www.prnewswire.com en
Packs

18650 batteries are commonly used in packs, where a battery management system (BMS) is required, especially once cells age and perform differently. BMS boards balance the voltage of cells in series and protect against over- and under-discharge.
