Lithium batteries are widely used in various neighbourhoods because of their maintenance-free and high energy density. Our daily life is everywhere in the figure of lithium batteries. Lithium batteries have a series of advantages, In this article, we will take you to understand whether the lithium battery can be wet as well as lithium batteries are wet after the changes.

Can lithium batteries be wetted?

Theoretically, lithium batteries can be mildly wet, because manufacturers will be in the process of producing lithium batteries, will take into account the waterproof performance of lithium batteries, but still do not recommend that you test the waterproof performance of lithium batteries, lithium batteries will be wet on purpose.

The specific waterproof grade of lithium battery is related to the quality of lithium battery and the design of the manufacturer, now the waterproof grade of lithium battery is mainly IP65, IP67 and IP68, for example, IP65 lithium batteries can resist the low water pressure jet from all directions of the water, more suitable for domestic use, IP67 lithium batteries can be used in shallow water or temporary deep water work, and IP68 waterproof performance will be better, it can be used in deep water for a long time. It can work in deep water for a long time. Generally, the latter two waterproof grade lithium batteries will be used in equipment that requires underwater work.

When choosing lithium batteries, you need to understand the relevant waterproof grade with the sales staff in time, and follow the instructions of lithium batteries to avoid potential danger.

What will happen if the lithium battery is wet?

Lithium battery short circuit: lithium battery is wet, the probability that the internal environment of the lithium battery will change, and there will be an abnormal chemical reaction, in this case the battery may be directly short-circuit.

Safety accidents: when the lithium battery into the water, its internal equivalent of the external environment connected, people then touch the battery will be electrocuted. When your lithium battery due to moisture in the air, the moisture inside the battery decomposition of hydrogen, hydrogen is extremely flammable gas, in the event that you do not know, if you charge the battery, then lithium batteries may explode.

Lithium battery capacity becomes smaller: after the lithium battery is wet, water may enter inside the battery, the water will decompose to produce oxygen, oxidize the multi-hollow septum inside the lithium battery, at the same time in the electrolyte of the lithium salt solution in the presence of water will also be decomposed, lithium battery electrode inside the battery and the electrolyte is reduced, then its capacity is also reduced.

Useful life is reduced: cathode lithium oxide and graphite and water or hydrolysis products will decompose when they come into contact with each other, if there is water inside the lithium battery for a long time, the cathode and anode accelerate to become shorter, so that the service life of lithium batteries will accelerate to reduce.

What should be done after the lithium battery is soaked?

If the lithium battery is only wet on the outside, no water inside, the lithium battery will be placed in a cool place to dry, test the lithium battery does not appear fault, or can continue to use. But don’t use high temperature hair dryer or other heating equipment to dry the lithium battery directly in order to make it dry quickly, to prevent the lithium battery from exploding due to high temperature.

If your lithium battery has water inside, please do not touch the battery directly with your hands to avoid electric shock. Use insulated gloves, turn off the equipment connected to the battery first, wipe the moisture on the surface of the battery as soon as possible, and send it to the repair store for repair in time, according to the damaged parts inside the lithium battery to decide whether to replace it or not, if the battery has been seriously damaged inside, it is recommended that you can directly recycle the damaged batteries and then buy new lithium batteries.

Water inside the lithium battery is very dangerous, in dealing with wet lithium batteries to do a good job of protection measures, we recommend that if you do not have the relevant knowledge of electricity, please do not deal with their own, looking for a professional to solve the problem for you will be safer.

What measures can I take to minimize the moisture of lithium batteries?

Placement environment: Lithium batteries should be placed in a dry, cool place, so that the environment, the humidity of the air will be lower, and can enter the lithium battery internal moisture will be less. If the lithium battery is not used for a long time, it is more important to place the lithium battery in such an environment.

Avoid bumping: When the external lithium battery is damaged, it will be easier for water to enter inside. So avoiding bumps is an important precaution during use.

Use desiccant: If your environment inevitably has high humidity in the air, you can use desiccant nearby to reduce the moisture in the air.

Regular inspection: Regular inspection of your lithium batteries can check the state of use of your lithium batteries, perhaps when your lithium batteries have moisture phenomenon, but also can reduce your losses.

Conclusion

Although it is said that some lithium batteries before the purchase, the manufacturer has promised the lithium battery waterproof performance is good enough, but you still try not to let the lithium battery is soaked, lithium battery damage is a small problem, if there is a safety accident will be more than worth it.
