Another water-activated battery had been invented by Susumu Suzuki of Total System Conductor. Aluminium anodes are used on many water-activated batteries designed for use with salt water such as seawater. The HydroPak uses water-activated disposable fuel cartridges as an alternative to lead acid battery packs and portable generators.
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.

Lithium manganese oxide or Lithium nickel manganese cobalt oxide Yes 2008 ... Low self-discharge nickel–metal hydride battery: 500–1,500 [14] Lithium cobalt oxide ...
Aluminium-ion batteries (AIB) are a class of rechargeable battery in which aluminium ions serve as charge carriers. Aluminium can exchange three electrons per ion. Aluminium can exchange three electrons per ion.
[clarification needed] [20] [21] The energy density of these rechargeable batteries with copper intercalated manganese dioxide is reported to be over 160 Wh/L, the best among the aqueous-based chemistries. [21] It could be capable of energy densities comparable to lithium-ion (at least 250 Wh/L) if zinc utilization in the batteries were ...
Aluminium is still very cheap compared to other elements used to build batteries. Aluminium costs $2.51 per kilogram while lithium and nickel cost $12.59 and $17.12 per kilogram respectively. However, one other element typically used in aluminium air as a catalyst in the cathode is silver, which costs about $922 per kilogram (2024 prices).
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).
Aluminium–air battery is a non-rechargeable battery. Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using ...
