Electric motors using battery packs have been used for propulsion on submarines and electric boats and have been proposed for energy-efficient propulsion. [1] A marine steam turbine manufactured by MAN Energy Solutions. Development in liquefied natural gas (LNG) fueled engines are gaining recognition for their low emissions and cost advantages.
Lithium-ion in this case usually means lithium iron phosphate batteries, which although are heavier than other lithium-ion, is safer for marine application. They are expensive but in applications which need reliability and ruggedness like ferries which run most of the day (10–12 hours/day) this is the best option.
One of the main research efforts in the field of lithium-manganese oxide electrodes for lithium-ion batteries involves developing composite electrodes using structurally integrated layered Li 2 MnO 3, layered LiMnO 2, and spinel LiMn 2 O 4, with a chemical formula of x Li 2 MnO 3 • y Li 1+a Mn 2-a O 4 • z LiMnO 2, where x+y+z=1. The ...
These batteries are usually a secondary (rechargeable) battery, and are typically lithium-ion batteries. Traction batteries, specifically designed with a high ampere-hour capacity, are used in forklifts, electric golf carts, riding floor scrubbers, electric motorcycles, electric cars, trucks, vans, and other electric vehicles.

The ultracapacitors are made of activated carbon, and have an energy density of six watt-hours per kilogram (for comparison, a high-performance lithium-ion battery can achieve 200 watt-hours per kilogram), but the ultracapacitor bus is also cheaper than lithium-ion battery buses, about 40 percent less expensive, with a far superior reliability ...
A lithium polymer battery, or more correctly, lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly, and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. Highly conductive semisolid polymers form this electrolyte.

The traction battery operates at 400 V and has an energy density of 195 Wh/kg using 2170-sized cells, suggesting the weight of the 80 kWh battery is 410.3 kg (905 lb). [ 10 ] The battery uses 2170 cylindrical lithium-ion cells manufactured by Panasonic and integrated into the chassis in eight battery modules. [ 16 ]
