2. Sodium–sulfur battery - Wikipedia

   en.wikipedia.org/wiki/Sodium–sulfur_battery

   Cut-away schematic diagram of a sodium–sulfur battery. A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. [1] [2] This type of battery has a similar energy density to lithium-ion batteries, [3] and is fabricated from inexpensive and low-toxicity materials.

3. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   A battery pack is a set of any number of (preferably) identical batteries or individual battery cells. [1] [2] They may be configured in a series, parallel or a mixture of both to deliver the desired voltage and current.

4. Zinc–air battery - Wikipedia

   en.wikipedia.org/wiki/Zinc–air_battery

   Zinc–air batteries have higher energy density than many other types of battery because atmospheric air is one of the battery reactants, in contrast to battery types that require a material such as manganese dioxide in combination with zinc. Energy density, when measured by weight (mass) is known as specific energy. The following table shows ...

   An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. [ 1 ] While a significant majority of water vessels are powered by diesel engines , with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years.

7. 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.
