Is the inside of the lithium battery liquid or solid?

Custom battery electrolytes are liquid electrolyte and solid electrolyte.

Liquid electrolyte is mainly used in lithium-ion batteries, making customization of lithium-ion batteries relatively simple and inexpensive. It also gives lithium-ion batteries high conductivity and more stable internal chemical properties. The disadvantage is that it is easy to dissolve, and liquid electrolytes made from organic solvents can easily cause fires and explosions.

Solid electrolytes can also be divided into fully solid and gel types. Currently, gel electrolytes are convenient and mass-produced. The electrolyte is in a gel state and will not leak like a liquid, so it is safe. The outer packaging of solid-state lithium batteries uses soft packaging materials, which reduces the weight of the battery and cantake any form.

Detailed information

The choice of electrolyte has a great impact on the performance of lithium batteries. It should have good chemical stability, especially at higher potentials. It is not easy to decompose in high temperature environments, has high ionic conductivity, and must be inert to cathode and anode materials and cannot corrode them.

Since the charge and discharge potential of lithium batteries is high and the anode material is embedded with chemically active lithium, the electrolyte must use organic compounds and cannot contain water. However, the ionic conductivity of organic matter is not good, so soluble conductive salts should be added to organic solvents to improve the ionic conductivity. Currently, lithium-ion batteries mainly uses liquid electrolytes.

The lithium polymer battery itself does not contain electrolyte and is a conductive gel-like substance.

The soft batteries you are talking about should be soft lithium-ion batteries. Many of them in China are mislabeled as polymers.

The main reason for the softness of this type of battery is that too much electrolyte is added during the production process, or the baking process of the clamp or clamp formation is missing. , so it becomes soft. It is also possible that the outer aluminum plastic film may be damaged, which can also cause softening.

If it becomes soft and cannot be charged, it should be because the battery is swollen. If you leave it for a while, you will find that the battery is as hard as it can be. a rock.

Do not damageDo not age the battery at this time, as the lithium has been precipitated and lithium metal is very reactive and flammable.

It is recommended to replace the battery immediately.
