Battery leakage is the escape of chemicals, such as electrolytes, within an electric battery due to generation of pathways to the outside environment caused by factory or design defects, excessive gas generation, or physical damage to the battery.
This type of battery is also referred to as a lithium-ion battery [1] and is most commonly used for electric vehicles and electronics. [1] The first type of lithium battery was created by the British chemist M. Stanley Whittingham in the early 1970s and used titanium and lithium as the electrodes.
Side-view of water-activated radiosonde battery Radiosonde battery still in protective wrapper Typically, a large variety of aqueous solutions can be used in place of plain water. This battery type is specifically designed to pollute less (see environmentally friendly claims) due to the lesser use or the absence of heavy metals .
Severe PCB corrosion from a leaky PCB mounted Ni-Cd battery. Printed circuit boards (PCBs) are vulnerable to environmental influences; for example, the traces are corrosion-prone and may be improperly etched leaving partial shorts, while the vias may be insufficiently plated through or filled with solder. The traces may crack under mechanical ...
A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.

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.
