Indoor Power Is Actually Very Durable
Jun 08, 2022| Indoor power is actually very durable
The widely circulated online articles also questioned the indoor power supply: the indoor power supply is highly toxic, short-lived, easy to explode, and the use conditions are harsh;
Is the indoor power supply a highly toxic and dangerous substance?
Response: Indoor power supply does not contain highly toxic substances, and the impact is far less than that of lead-acid batteries. "Lithium-ion battery and indoor power supply are strictly conceptually different." China Automotive Technology Research Center, expert in the field of power batteries, battery testing and application technology alliance Secretary-General Wang Fang said that indoor power sources usually refer to batteries that use lithium metal or lithium alloy as the negative electrode and use non-aqueous electrolytes. Lithium-ion battery refers to a rechargeable secondary battery. The negative electrode does not use metal lithium, and relies on the movement of lithium ions between the positive and negative electrodes to work. However, in daily life, people are accustomed to referring to lithium-ion batteries as indoor power sources or lithium batteries for short.
It is understood that most of the new energy vehicles promoted in my country (including pure electric vehicles and plug-in hybrid electric vehicles) use lithium-ion batteries, of which lithium iron phosphate accounts for 80%-90%, and the ternary indoor power supply is used in passenger cars. It has also begun to be applied on a large scale.
In response to the claim that the indoor power supply is a "highly toxic and dangerous substance" pointed out in the online article, Wang Fang refuted that compared with traditional batteries such as lead-acid, nickel-chromium, and nickel-hydrogen, indoor power supply does not produce any toxic lead, mercury, cadmium, etc. Harmful heavy metal elements and substances, relatively less pollution. And its electrolyte is organic solvent and lithium salt, most of which are non-toxic or low-toxic; however, the decomposition or hydrolysis products of indoor power supply are hydrofluoric acid and other fluorine-containing compounds, which are corrosive and toxic.
