It is embedded in side), under the action of an external electric field, start positive constant-current charge process, in side of the positive electrode, lithium ion starts from iron phosphate lithium positive pole
(one or more of lithium iron phosphate positive material LiFePO4, LixMeyFePO4, LiFexMeyPO4's is mixed for adsorbent material
Close object.Me is the mixing of one or more of Mg, Al, Ti, Ni, Co, Mn, Mo, Nb.0 < x <, 1,0 < y < 1) in abjection
Into rich lithium liquid；In negative side, lithium ion is embedded into monophosphate monophosphate iron ion sieve adsorbent material (ferric phosphate ion sieve from brine

Several mixing；0 < x <, 1,0 < y < 1) in, by an electrolytic process, load can not meet constant current conditions, change into constant pressure
Charging, until electric current is less than setting value, positive electrolytic process terminates, i.e., for anode-side, lithium abjection process terminates；For yin
Pole, lithium telescopiny terminate.Entire forward direction process is first constant current constant pressure again.
Commutation: the polarity reversing for the voltage for being added in electrode, it may be assumed that original plus forward voltage electrode becomes this moment plus negative sense
Voltage；Original plus negative voltage electrode becomes this moment plus forward voltage.Trade-off is realized in external solution cooperation simultaneously.

Rich lithium liquid side out), cathode (being anode before commutation) is added in brine side (lithium ion insertion side), under the action of an external electric field, starts just
To constant-current charge process, in side of the positive electrode, lithium ion starts to deviate from from LiFePO4 adsorbent material into rich lithium liquid, in cathode
Side, lithium ion in brine from being embedded into ferrous phosphate adsorbent material, and by an electrolytic process, load can not meet constant current item
Part changes into constant-voltage charge, and until electric current is less than setting value, negative sense electrolytic process terminates, or says that, for anode-side, lithium deviates from process
Terminate；For cathode, lithium telescopiny terminates, and therefore, entire reverse procedure is also first constant current constant voltage process again.
Existing power-supply device can generally meet positive first constant current constant-voltage charge process again, can only be into for reverse procedure
Row constant-current discharge, constant-resistance discharge, invariable power electric discharge, in other words can only reversed constant-current charge, constant-resistance charging, invariable power charging.Cause
This cannot accomplish the process of first constant current constant pressure again in reverse procedure.
