Description
Technical field
The utility model relates to lithium battery security technology area, particularly relates to a kind of lithium battery explosion-resistant enclosure.
Background technology
" lithium battery " is a class is negative material, the battery using non-aqueous electrolytic solution by lithium metal or lithium alloy.Because the chemical characteristic of lithium metal is very active, make the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium battery is not applied for a long time.Along with the development of science and technology, present lithium battery becomes main flow.Lithium battery is widely used in the accumulation power supply systems such as waterpower, firepower, wind-force and solar power station, the uninterrupted power supply of post and telecommunications, and multiple field such as electric tool, electric bicycle, battery-operated motor cycle, electric automobile, military equipment, Aero-Space.
The high capacity lithium ion battery of current exploitation has started to try out in electric automobile, estimates one of major impetus power supply becoming 21 century electric automobile, and will be applied in artificial satellite, Aero-Space and energy storage.Along with the pressure of the in short supply and global environmental protection aspect of world energy sources, lithium electricity is just being widely used in electric motor car industry, particularly the appearance of LiFePO 4 material battery, has more promoted development and the application of lithium battery industry.But general lithium battery poor stability, easily blasts.For the problems referred to above, in current high capacity cell plastic housing explosion-proof technology, be mainly spring explosion-proof valve, explosion-proof elastic force is difficult to reach accurately consistent, and spring is subject to the impact of electrolyte and peripheral environment air plankton, and the overwhelming majority can produce corrosion, its elastic performance is affected greatly, be difficult to reach desirable explosion-proof effect, or owing to too tightly losing explosion-proof meaning, or too pine causes leakage to cause battery to scrap.Simultaneously when the pressure of inside battery sharply increases, the entirety of housing often can be caused to split.
