5 Most Advanced Battery Technologies That Will Power The Future

1. Metal Hydrogen Battery 

Metal hydrogen battery, also known as nickel-hydrogen battery, is a rechargeable electrochemical power source based on nickel and hydrogen. It differs from a nickel–metal hydride battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi pressure. The specific energy of this battery is 55 to 75 Wh/kg. It has a charge efficiency of 85% and a cycle durability of more than 20,000 cycles.

The metal hydrogen batteries have properties which make them attractive for electrical energy storage in satellites. For example, the ISS, Mercury Messenger, Mars Odyssey and the Mars Global Surveyor are equipped with nickel–hydrogen batteries. They are also being used in the Hubble Space Telescope which is the first application of nickel-hydrogen batteries for a major Low Earth Orbit (LEO) mission. By converting the chemical energy stored in gasses into electrical energy, the battery can be used to power electric drive motors, temporary storage batteries or a variety of other applications.
