Viru kuerzem hunn d&39;Fuerscher vun der Stanford University, USA en neien intelligenten elektrostatesche Spinning-Separator erstallt, deen e Wärme-Ausléisermechanismus huet, deen Flammschutzmëttelen enthält, déi fir d&39;alarm Lithium-Ion-Batterieverbrennung benotzt kënne ginn. An dëser Konfiguratioun ass de Flam retardant bannent der Polymer Ënnerhalt Shell verpakt, an der Anti-Flam retardant Pen gëtt direkt an der electrolyte opgeléist, an dann ass d&39;Batterie Funktioun negativ beaflosst. Wann d&39;Hëtzt am Lithium Ion Batterie Pack ze héich ass, wäert d&39;Batterie Ënnerhalt Shell wéinst héijen Temperaturen opléisen, de Flam retardant fräiginn, a benotzt dann d&39;héich brennbar Elektrolytverbrennung.

1. Apply the original charger: charging time is the high time period of the explosive event of lithium ion battery pack. Original Ladegerät ass méi staark wéi kompatibel Ladegeräter fir d&39;Batteriesécherheet ze garantéieren.

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. sinn déi wichteg Ursaach vun der Explosioun vun Lithium Ion Batterie Pak, probéieren d&39;Batterie an engem stabil Ëmwelt ze maachen, ewech vun der lokal 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.
