What different types of batteries exist?

Lithium-Nickel-Manganese-Cobalt (NMC):

NMC chemistry provides the greatest balance of power, energy, safety, and overall performance compared to other lithium-ion technologies, including Lithium Titanate.

These batteries are suitable for powering fully-electric or hybrid-electric ships.

Lithium-Titanate-Oxide (LTO):

Compared to other lithium-ion battery chemistries, LTO batteries tend to have an average power rating and lower energy density. They have an ultra fast charge and discharge capability, extremely long cycle life (>60,000+ cycles at 100% DOD) and are capable of a fast charge in <10 minutes.
