Lithium battery burning toxic?

 Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain lithium in metallic form and are capable of being recharged. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance-to-price ratio are better than lithium ion batteries. Due to its own high technical requirements restrictions, now only a small number of companies in a few countries are producing such lithium metal batteries. So lithium batteries incineration is toxic? Here is an introduction for you.


  Lithium polymer batteries are known to be the most unstable batteries, far more than nickel-metal hydride nickel cadmium, especially the battery pack class, long in the case of indeterminate sudden spontaneous combustion, expansion bulge, fire, explosion, the occurrence of smoke damage think big, the lighter leads to dizziness and disgust, the heavier will lead to lithium poisoning coma, lithium batteries whose charging and discharging are required to battery built-in short-circuit protection circuit control, but due to high monomer voltage small internal resistance small storage capacity high Low cost, many unknown small enterprises mass production, is widely used.


  The burning of mercury-containing batteries will mainly release sulfur dioxide, manganese dioxide, mercury, zinc oxide and carbon dioxide, among which sulfur dioxide will constitute sulfur trioxide and eventually become sulfuric acid, causing acid rain damage to the land, manganese and mercury are heavy metals, which are very damaging to the land, especially mercury, sodium peroxide, zinc oxide and other substances will occur after the burning of alkaline batteries, among which heavy metal salts are also very damaging substances


  Sodium peroxide at the beginning will constitute sodium hydroxide, a strong alkali, which will salinize the land, but will eventually constitute sodium carbonate, which is not harmful.
