Third generation space power system after pond.Currently, international lithium ion battery comes into engineering in space power system field and answers
Use the stage.As a kind of secondary cell for being widely used in spatial overlay, working condition directly affect spacecraft
The rail flight service life.Since the charge characteristic of lithium ion battery is more special, it is further continued for charging after its charging reaches final voltage
If, it will just will lead to overcharge.During the overcharge of battery, continuously it is embedded in from the lithium ion of anode abjection negative
Pole, after the position that cathode can accommodate lithium ion is all occupied full, the subsequent lithium ion from anode abjection have to be in negative terminal surface
Deposition becomes lithium metal, and the Li dendrite that negative terminal surface generates, which may puncture diaphragm, makes battery internal short-circuit.Overcharge will lead to electric power storage
Pond fever, the thermal runaway as caused by overcharge may be from two aspects: it is on the one hand the Joule heat that electric current flows through generation, it is another
Aspect is the reaction heat that the side reaction that positive and negative electrode occurs generates.When over-charging of battery, cathode voltage is gradually risen, when taking off for anode
When lithium amount is excessive, de- lithium process is also more and more difficult, this causes the internal resistance of battery increased dramatically, therefore generates a large amount of joule
Heat becomes apparent in the charging of big multiplying power.The high-voltage anode oxidation solvent of overcharging state causes a large amount of heat to generate, temperature liter
Also with electrolyte exothermic reaction can occur for cathode after height.When rate of heat release is greater than the rate of heat dispation of battery, temperature is risen to centainly
When degree, thermal runaway will occur.It can be seen that overcharge will seriously damage lithium battery, to the electrical property and cycle life of battery
Deng totally unfavorable.
In order to effectively extend the service life of lithium battery, the reliability of power-supply system, usual spacecraft power supply system are improved
Different charging voltage gears will be designed for lithium battery.Currently, in domestic spacecraft power supply system, lithium battery charging voltage
Adjusting be to be realized by ground remote control, independence is lower and only for single bay section charging path.In-orbit period, work as spacecraft
When outside TT & c arc, once lead to certain section monomer electricity due to declining drop etc. single battery open circuit, short circuit, abnormal performance
Pond failure, accumulator battery voltage decline, just impenetrably face sends the charging final pressure that telecommand switches battery group in time
Point, so that continuing overcharge to be eventually led to, to the functionality of power-supply system to battery charging with higher charging voltage
It causes to seriously affect, influences the success or failure of entire spacecraft flight task indirectly.
