High surface area, good electrical conductivity, and low weight. Aluminum foil is used as a cathode current collector for Lithium-ion batteries. It is a critical component in the construction of the battery, as it helps to conduct electricity and acts as a barrier to prevent the electrolyte from leaking.
Metallic foil anodes have long attracted researchers’ attention in lithium rechargeable batteries since the early 1970s when Rao et al. demonstrated that the lithium-aluminum anode can effectively suppress Li dendrite formation .
I've been reading on safety protocols on Li batteries and I seem to remember that Lithium itself is extremely reactive to water. However, FAA regulations recommend using water to douse the device to keep it cool.
To protect lithium batteries from water, use waterproof casings or enclosures for devices containing batteries. Store batteries in dry environments, avoid exposure to moisture and use waterproof containers or bags if there’s a risk of water exposure.
Submerging a lithium battery in water can cause a short circuit, leading to immediate damage, overheating, and potential fire or explosion due to the reaction between water and the battery’s internal components. Are lithium batteries waterproof? Lithium batteries are not inherently waterproof.
Lithium batteries are denser than water and typically sink rather than float. However, the buoyancy could depend on factors like battery size, shape, and packaging. Why is water bad for batteries?
