Learn the key feature of each Li-ion in a summary table.
The term lithium-ion points to a family of batteries that shares similarities, but the chemistries can vary greatly. Li-cobalt, Li-manganese, NMC and Li-aluminum are similar in that they deliver high capacity and are used in portable applications. Li-phosphate and Li-titanate have lower voltages and have less capacity, but are very durable. These batteries are mainly found in wheeled and stationary uses. Table 1 summarizes the characteristics of major Li-ion batteries.

|Comments||High energy, limited power. Market share has stabilized.||High power, less capacity; safer than Li-cobalt; often mixed with NMC to improve performance.||High capacity and high power. Market share is increasing. Also NCM, CMN, MNC, MCN||Flat discharge voltage, high power low capacity, very safe; elevated self-discharge.||Highest capacity with moderate power. Similar to Li-cobalt.||Long life, fast charge, wide temperature range and safe. Low capacity, expensive.|
