4. Electric boat - Wikipedia

   en.wikipedia.org/wiki/Electric_boat

   Electric energy has to be obtained for the battery bank from some source like the sun. A mains charger allows the boat to be charged from shore-side power when available. Shore-based power stations are subject to much stricter environmental controls than the average marine diesel or outboard motor.

5. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

6. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.
