Water based electrolyte in battery has problem of creating dangerous hydrogen gas, because of containing hydrogen ion in electrolyte. It causes many metals in cathode cannot be a re-chargeable cell.

Detergent can dissolve in oil and it is without hydrogen ion, so Detergent oil can be a choice for next generation’s electrolyte.

> metal- Detergent salt in oil liquid as electrolyte

Water Vacuum Energy Storage
(Concept of Usage water's pressue)

Compressed air Energy Storage has disadvantages of thermal (heat) creation and absorption during compression and de-compression respectively.

For using water pressure as energy storage, water is liquid and liquid is no the limitation of "Idea Gas Law", which PV/T= constant (where P= pressure, V= volume, T=Temperature in term of absolute temperature). The water pressure's energy storage is similar to water dam, but it does not require building dam. Only civil work is to build enclosed container and put the container under water or sea.

For water pressure, it increases more 1 bar (1 atmospheric pressure) per water depth increases 10 meters.

Pw= (1+wd/10) ,where Pw= water pressure in bar, 1= atmospheric pressure, wd= water depth in meters

Energy required to remove water is: E=Pw* ΔV ,where Pw= water pressure in bar, ΔV= volume of water to be removed

Energy produced to fill in water is: E=Pw* ΔV ,where Pw= water pressure in bar, ΔV= volume of water to be removed

It seems the same energy used and returned for water's removal and filling cycle. It is very similar to water dam.
