''While Li-aluminum (NCA) is the clear winner by storing more capacity than other systems, this only applies to specific energy.''
 
''In terms of specific power and thermal stability, Li-manganese (LMO) and Li-phosphate (LFP) are superior.''
 
''Li-titanate (LTO) may have low capacity but this chemistry outlives most other batteries in terms of life span and also has the best cold temperature performance.''

|Comments
|High power but less capacity; safer than Li-cobalt; commonly mixed with NMC to improve performance.
|Provides high capacity and high power. Serves as Hybrid Cell. Favorite chemistry for many uses; market share is increasing.
|Very flat voltage discharge curve but low capacity. One of safest Li-ions. Used for special markets. Elevated self-discharge.
|Shares similarities with Li-cobalt. Serves as Energy Cell.
|Long life, fast charge, wide temperature range but low specific energy and expensive. Among safest Li-ion batteries.

LMO et NCA, mis en commentaire <!--
=== NCA ===
''Most LMO batteries blend with NMC to improve the specific energy and prolong the life span. This combination brings out the best in each system, and the LMO-NMC is chosen for most electric vehicles, such as the Nissan Leaf, Chevy Volt and BMW i3. The LMO part of the battery, which can be about 30 percent, provides high current boost on acceleration; the NMC part gives the long driving range.''
