What is electrolyte?
Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., and its representative content varies greatly in different industries. There are electrolytes in living organisms (also called electrolytes), there are also electrolytes used in the battery industry, as well as electrolytes in electrolytic capacitors, supercapacitors, and other industries.
The compositions of electrolytes used in different industries vary greatly, or are even completely different. For example, the human body’s electrolytes are mainly composed of water, sodium chloride, pH buffering substances, etc.; the electrolyte of aluminum electrolyte capacitors contains major solvents such as GBL; the supercapacitor electrolyte contains propylene carbonate or acetonitrile as the main solvent; the electrolyte of lithium manganese primary battery contains main solvents such as propylene carbonate and ethylene glycol dimethyl ether; lithium-ion battery electrolyte contains main solvents such as ethylene carbonate, dimethyl carbonate, ethyl methyl carbonate and diethyl carbonate. Their respective conductive salts are also completely different, such as sodium chloride in the human body, tetraethylammonium tetrafluoroborate in the supercapacitor electrolyte, and lithium perchlorate or lithium triflate commonly used in lithium manganese primary batteries. And in lithium-ion batteries, it is lithium hexafluorophosphate.
There are many advantages to using electrolyte as a cathode. The first is that the contact area between the liquid and the medium is large, which is helpful to increase the capacitance. Secondly, electrolytic capacitors made with electrolyte can withstand high temperatures, so they can pass wave soldering (wave soldering is an important process for SMT patch installation), and they also have relatively strong voltage resistance. However, the electrolyte also has shortcomings, and there are potential safety hazards, such as environmental pollution, fire, and human injury caused by leakage.
What are the dangers of electrolyte leakage?
- Inhalation hazards
Fine gas suspensions in the electrolyte are easily mixed into the atmosphere. Especially when the temperature rises, the poisonous gas in the electrolyte is easily inhaled, which can cause neurotoxicity in the human body. Lithium battery electrolyte can cause respiratory, eye, and skin irritation, with symptoms including cough, diarrhea, headache, blindness, and skin burning.
- Skin contact hazards
When a large amount of gas is released, the electrolyte is easy to splash out and meet the skin, which can cause skin burns, irritation, and allergic skin diseases. It can even cause severe tissue fragmentation and coagulation, skin whitening, blisters, irritating eczema and ulcerated dermatitis symptoms.
- Risk of eye contact
The electrolyte can not only pass through the skin, but also stick along the facial skin and into the eyes. If not treated in time, it can cause further damage to the retina and eye membranes, and cause symptoms such as pain, irritation, eye warmth, tearing, eye itching, and itching.
- Dangers of dietary intake
When improperly maintained, the electrolyte of the electrolyte splashes into food, which can cause harmful substances such as ions, acids, alkali impurities, and heavy metals in the liquid to contaminate food and water sources. These substances have an extremely serious impact on human health and can cause symptoms such as nausea, vomiting, general discomfort, stomach pain, gastrointestinal soreness, and even death.
- Flammability hazards
If there is contamination or large amounts of leakage, flammable gases can easily form. Once a fire occurs, the lithium battery electrolyte flame will become violent and the fire will accelerate significantly, increasing the disaster.
- Environmental pollution hazards
The discharge of electrolyte not only damages the environment, but also affects the fertility of the soil. And it cannot be decomposed, even if it is affected by natural degradation in the atmosphere and water, it will remain in the surface soil and water. Long-term contamination of land and water sources may also pose potential threats to human health.
How to prevent electrolyte leakage?
The use of anti-penetration absorbent materials can effectively prevent electrolyte leakage. Melamine foam, for example, can be used to absorb leaked electrolyte after the adapter’s electrolytic capacitor fails to avoid safety issues such as power short circuit caused by electrolyte.
Excellent properties of melamine foam anti-penetration absorbent material:
1) 10 times liquid absorption performance
2) Excellent liquid storage performance
3) Long-term insulation performance and anti-static performance
4) Excellent acid and alkali resistance, corrosion resistance
5) Anti-mildew, anti-UV
6) Wide operating temperature, -196 degrees ~ 200 degrees
7) Melamine foam is non-fibrous material, does not contain any dust, does not contain any halogenated hydrocarbons, flame retardants or toxic heavy metals
Applicable Products:
Lithium batteries, supercapacitors, charging adapters, mobile electronic devices, energy storage systems, power batteries, sodium-ion batteries, etc.
