Nylig har forskerne ved Stanford University, USA laget en ny intelligent elektrostatisk spinnende separator, som har en varmeutløsermekanisme, som inneholder flammehemmere, som kan brukes til varslet litiumionbatteriforbrenning. I denne konfigurasjonen er flammehemmeren pakket inne i polymervedlikeholdsskallet, og den anti-flammehemmende pennen blir direkte oppløst i elektrolytten, og deretter påvirkes batterifunksjonen negativt. Når varmen inne i litiumionbatteripakken er for høy, vil batterivedlikeholdsskallet løses opp på grunn av høye temperaturer, frigjøre flammehemmeren og deretter bruke den høyantennelige elektrolyttforbrenningen.

1. Apply the original charger: charging time is the high time period of the explosive event of lithium ion battery pack. Original lader er kraftigere enn kompatibel lader for å sikre batterisikkerhet.

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. er den viktige årsaken til eksplosjonen av litium ion batteripakke, prøv å gjøre batteriet i et stabilt miljø, vekk fra lokale lokale. 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.
