Shown in referring to Fig.1, the invention discloses a kind of high security lithium ion batteries, including several Li-ion batteries piles 3
And the sealed cell case of battery is accommodated, Li-ion batteries piles 3 are made of more than one lithium-ion battery monomer 31, battery case
It is made of babinet 1 and case lid 11, insulation and liquescent halon extinguishing agent, liquified Halon is filled in the battery case
Extinguishing chemical 2 is filled into the gap between lithium-ion battery monomer 31.
It, can when battery pack leads to battery pack temperature exception due to the internal factors such as abuse, short circuit or outside heat are impacted
By the steam of the export evaporation of relief valve 12, to take away the extra heat of battery pack, and form one layer of gas inside and outside battery case
Body extinguishing chemical isolation strip, and inerting ambient air inhibit Li-ion batteries piles 3 further out of control or put out fire outside battery pack
Source.
If battery case is caused battery case broken, battery case air pressure inside to reduce by external physical impact, alkyl halide fire extinguishing
Agent is evaporated rapidly, is reduced battery pack temperature and is formed low temperature inerting air insulated band inside and around battery case, can inhibit lithium
Situations such as out of control or even fire that ion battery blastic deformation occurs, occurs.
Alkyl halide in battery case is liquefied gas extinguishing agent, so battery case must be hermetically sealed, and can be held
By at least pressure of 1.5~3.0MPa；These types of halon extinguishing agent is non-corrosive, and therefore, the material of battery box enclosure does not have
The limitation that corrosion resistance requires, only with the pressure requirements for ensureing battery case.
