Today's Lithium-ion Chemistries -
Li-ion Cobalt Oxide cells have become the "work-horse cells" of the Li-ion industry. These cells are used in a wide range of consumer battery packs today. Other specialized Li-ion chemistries have become available which appear to be good fits for certain applications but still lack the all-around capabilities of the Cobalt Oxide chemistry. Below is a partial list of commercially available Li-ion chemistry variants -
- Cobalt Oxide (many vendors and form factors)
- A123 System's Nanophosphate technology
- Altairnano's Nano-structured Lithium Titanate Oxide (LTO) chemistry
- Valence's Lithium Phosphate technology
- And others
Boundless' "Cell Agnostic" design approach has been and will continue to be a key differentiator for Boundless' customers.
At a Glance - Li-ion Chemistry Comparison
