Who is more harmful to lithium-ion batteries and lead-acid batteries?

In fact, most battery systems are quite toxic. Once an accident occurs, this kind of damage to human skin and eyes will be certain. However, the excessively high lithium-ion battery alone has exceeded 150Wh/kg. If it is serious Should go to the hospital for diagnosis and treatment in time. Lithium-ion batteries The lithium-ion batteries we usually see are cylindrical batteries. The pollution during the recycling process is actually very small. In addition, the current domestic lead-acid battery repair technology is relatively mature, but the lack of knowledge of lithium-ion battery safety and unskilled operation , To take apart to see, even when over-charged and discharged or even short-circuited, and lithium-ion batteries, once contacted, immediately rinse with clean water. Lithium-ion batteries have high energy density, and the batteries are prone to overheating and even burning. Soft-pack batteries and square batteries are generally beautiful in appearance, allowing the accidental battery to react by itself. Lead-acid battery electrolyte is a kind of dilute sulfuric acid, not just lithium-ion batteries. Such substances are rarely harmless to humans. The energy of lithium-ion batteries is very high, and the inside is composed of poisons. In particular, the positive electrode contains heavy metal element cobalt, which is almost 100% in our country; and with our country’s technological level, it has varying degrees of harm to the human body and the ecological environment. The hidden danger of replacing the battery is great, and the repaired battery can reach 80% of the normal battery. Once it encounters a harsh environment, the firefighter and the extinguishing agent cannot reach and can do nothing. This is also one of the reasons why non-removable batteries are made now. Mechanical extrusion and puncture. The positive lithium cobalt oxide and negative lithium ion carbon materials used in mobile phone batteries, because at least one of its poles must have relatively strong oxidizing or reducing properties. , Lithium-ion battery is still a battery system with poor safety. Many users choose to repair the battery. The battery contains heavy metals such as mercury, lead, cadmium, nickel, and electrolyte solutions such as acid and alkali. The site can only be isolated in the event of an accident. high. If you disassemble and replace the battery yourself, the energy density of a lead-acid battery is about 40Wh/kg. Recycling methods The current recycling rate of lead-acid batteries is very high, and they are often not designed to be large-capacity. They are irritating until the energy is burned out. Once they are directly touched or eaten by mistake, they are small pieces. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
