Na nso nso a, ndị na-eme nchọpụta nke Stanford University, USA kere ọhụrụ nwere ọgụgụ isi electrostatic spinning separator, nke nwere okpomọkụ na-akpali usoro, nke nwere ire ọkụ retardants, nke a pụrụ iji maka njikere lithium ion batrị combustion. N&39;ime nhazi a, a na-etinye ọkụ ọkụ n&39;ime mkpuchi mkpuchi polymer, na pen na-egbochi ire ọkụ na-agbaze ozugbo n&39;ime electrolyte, mgbe ahụ, ọrụ batrị na-emetụta nke ọma. Mgbe okpomọkụ dị n&39;ime mkpọ batrị lithium ion dị oke elu, shei na-arụ ọrụ batrị ga-agbaze n&39;ihi oke okpomọkụ, hapụ ire ọkụ, wee jiri ọkụ ọkụ electrolyte combustion.

1. Apply the original charger: charging time is the high time period of the explosive event of lithium ion battery pack. Chaja mbụ dị ike karịa chaja dakọtara iji hụ na nchekwa batrị.

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. bụ ihe dị mkpa na-akpata mgbawa nke ngwugwu batrị lithium ion, gbalịa mee batrị ahụ na gburugburu ebe kwụsiri ike, pụọ na mpaghara mpaghara. 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.
