An aqueous battery is an electric battery that uses a water-based solution as an electrolyte. The aqueous batteries are known since 1860s, do not have the energy density and cycle life required by the grid storage and electric vehicles , [ 1 ] but are considered safe, reliable and inexpensive in comparison with the lithium-ion ones.

The polysulfide–bromine battery (PSB; sometimes polysulphide–polybromide or "bromine–sulfur") is a type of rechargeable electric battery that stores electrical energy in liquids, such as water-based solutions of two salts: sodium bromide and sodium polysulfide. It is a type of redox (reduction–oxidation) flow battery.
Aqueous Li-ion batteries have been of great interest for military use due to their safety and durability. Unlike the high voltage yet volatile non-aqueous Li-ion batteries, aqueous Li-ion batteries have the potential to serve as a more reliable energy source on the battlefield, because external damage to the battery would not diminish performance or cause it to explode.
One significant benefit of aqueous zinc-ion batteries (AZIBs) is their lower environmental impacts compared to other battery chemistries like lithium-ion (LIB) or sodium-ion (NIB) batteries. The chemistry of AZIBs means they can be assembled under ambient conditions without a controlled inert, oxygen and moisture-free environment like LIBs or ...
The battery materials are non-toxic. [23] As of early 2014, the cathode used manganese oxide and relies on intercalation reactions. The anode was a titanium phosphate (NaTi 2 (PO 4) 3). [24] The electrolyte was <5M NaClO 4. [25] A synthetic cotton separator was reported. [26] The electrode layers were unusually thick (>2 mm).
A battery converts chemical energy to electrical energy and is composed of three general parts: Anode (positive electrode) Cathode (negative electrode) Electrolyte; The anode and cathode have two different chemical potentials, which depend on the reactions that occur at either terminus.
In 2007, Michael Gratzel and his co-workers at the University of Geneva reported lithium-ion batteries, where the electroactive solids are stored as pure (i.e. without binders, conductive additives, current collectors) powders in tanks, and washed by liquids with dissolved redox couples, capable of electron exchange with the electroactive ...
Anode-free lithium ion batteries have been demonstrated using a variety of cathode materials, such as LiFePO 4, LiCoO 2, and LiNi 1/3 Mn 1/3 Co 1/3 (NMC 111).. These intercalation-type cathodes typically offer limited Li content (14.3 at.% for LiFePO4, 25 at.% for LiCoO2 and LiNixCoyMn1-x-yO2), although they remain the primary research targets. [2]
