Description
Technical field
The present invention relates to a kind of high temperature lithium Asia cylindrical batteries；Especially a kind of high security prevents high temperature lithium Asia cylindrical battery
Passivation system.
Background technique
Lithium Asia battery is as modern intelligence instrument (referring mainly to intelligent water, electricity, gas, hotlist meter) mainstream power supply.The sub- electricity of lithium
The no unique advantage of other intrinsic electrochmical power sources of pond；Such as high and stable operating voltage；Temperature use scope is wide；High-energy is close
Degree；Long shelf-life；It is pollution-free.But lithium thionyl chloride cell the shortcomings that there are voltage delay.
The reason of influencing voltage delay is to form densification in its positive electrode surface after being in contact due to lithium metal with thionyl chloride
Lithium chloride film.This tunic slows down the continuation fast chemical reaction between lithium and thionyl chloride to a certain extent, due to electricity
Pond generates the residue deposition of trace impurity and single sulphur on the surface of carbon pores in electric discharge, to lead to the conclusion that " storage
Time is longer, and storage temperature is higher, this tunic is thicker." since lithium chloride film is ion conductor, non-conducting electronics, then storing
Battery afterwards could must normally export biggish electric current after eliminating this tunic when high current uses again, guarantee compared with senior engineer
Make voltage.Internal resistance value is larger during abolishing passivating film, connect between occurring as soon as voltage transient after electrical appliance or resistance decline compared with
It is low.Voltage is being gradually increasing after several seconds.Whether this is normal good phenomenon, do not worry battery without electricity.This is the sub- electricity of lithium
The characteristic in pond.Electrochemical educational circles be referred to as " voltage delay ", battery lag degree and Battery storage time length, storage temperature and
There is this close relationship using the size of electric current and water content, the electro-hydraulic purity of battery.The battery storage time is longer, storage
Temperature is higher, and electric current is bigger, and battery more lags, and load voltage is lower.Battery lag can be solved fundamentally.In electricity
Some higher additives of activity are added in pond, battery passivation film is without battery is in high activity state for a long time.Electricity
The self discharge in pond just becomes larger.The use and storage service life of battery just reduces.The passivating film of battery has dual character in a word, only
The more communication and discussion of user and producer are wanted, are not unconquerable problems.
In using power supply system of the disposable lithium Asia battery as backup power source.Such as in wireless gas meter, electricity is done
Pond is as main power supply, and disposable lithium Asia battery is as backup power source, when dry cell power supply is normal, uses the electricity of dry cell
Amount；When dry cell is without electricity, in order to guarantee being normally carried out for wireless telecommunications, powered using lithium Asia battery.Due to lithium Asia battery
It is pre- in gas meter, flow meter, in order to guarantee the service life of lithium Asia battery, the very small lithium Asia battery of self discharge need to be selected.
Generally conventional long-life batteries will receive the influence of lithium Asia battery (lithium/thinly chloride) distinctive passivating film,
It is long-term place (or not working) after, unexpected use, which will appear voltage, to be reduced, can not discharging current the case where, cause battery to seem
It is no longer valid.
