What is the method of preventing the explosion of lithium ion battery packs?

ଲେଖକ: ଆଇଫ୍ଲୋପାୱାର - Portable Power Station supplementum

Së fundmi, studiuesit e Universitetit Stanford, SHBA kanë krijuar një ndarës të ri inteligjent elektrostatik rrotullues, i cili ka një mekanizëm ndezës të nxehtësisë, i cili përmban retardantë flakë, të cilët mund të përdoren për djegien alarmuese të baterive me jon litium. Në këtë konfigurim, retardanti i flakës paketohet brenda guaskës së mirëmbajtjes së polimerit, dhe stilolapsi kundër zjarrit shpërndahet drejtpërdrejt në elektrolit, dhe më pas funksioni i baterisë ndikohet negativisht. Kur nxehtësia brenda paketës së baterisë me jon litium është shumë e lartë, guaska e mirëmbajtjes së baterisë do të shpërndahet për shkak të temperaturave të larta, do të çlirojë retardantin e flakës dhe më pas do të përdorë djegien e elektrolitit me djegie të lartë.

1. Apply the original charger: charging time is the high time period of the explosive event of lithium ion battery pack. Karikuesi origjinal është më i fuqishëm se karikuesi i pajtueshëm për të garantuar sigurinë e baterisë.

2. Apply a firm battery: try to purchase the original battery or a famous brand battery, such as the lithium-ion battery of Haobo Battery, do not purchase second-hand goods or parallel to save money, such batteries may be repaired, not as good as the original battery. 3.

Do not place the battery pack in a pole environment: high temperature, bumps, etc. janë shkaku i rëndësishëm i shpërthimit të paketës së baterive litium-jon, përpiquni ta bëni baterinë në një mjedis të qëndrueshëm, larg lokalit lokal. 4.

Do not check the modification: After the modification, the battery may have an environment that has not been considered before, adding safety hazards. The chain reaction of the hydroxide radicals during the reaction of the lithium-ion battery continues to discharge a large amount of heat, which is a tight source that causes the battery to burn or explode, then the anti-ion battery is in the measures of fire or explosion, as shown below. 1.

Protection by external dedicated protection circuitry, such as: overcharge with a lithium ion battery, install a PTC polymer switch or explosion-proof safety valve in the safety cap of the battery. 2, the thermal stability of the lithium ion battery is related to the type of the positive material, the electrolyte. By optimizing synthetic conditions, improved synthetic methods, synthetic, synthetic, synthetic positive materials; or use composite technologies such as doping techniques, surface cladding techniques (such as coating techniques) to improve the thermal stability of the positive electrode material.

3. Weakly oxidation of the surface of the carbon material, such as: reduction, doping, surface modification, etc., or using spherical, fibrous carbon negative electrode material to improve the thermal stability of the battery.

4, using a well-stable lithium salt, a potential stability and wide solvent to improve the thermal stability of the battery. Further, a certain amount of flame retardant (organic phosphorus flame retardant, silane, borate, etc.) is added to the organic electrolyte is also a tight way to improve battery safety.
