Specific embodiment
In relation to addressing other technologies content, feature and effect before the utility model, following cooperation with reference to schema compared with
In the detailed description of good embodiment, can clearly it present.Schema in the utility model belongs to signal, is mostly intended to indicate each
Function relationship between device and each component, as shape and size then and not according to ratio drafting.It needs to illustrate
It is that in the accompanying drawings, the similar unit of structure is to be given the same reference numerals.In addition, in the absence of conflict, each reality in the present invention
The feature applied in example and embodiment can be combined with each other.
Fig. 2 is the battery recycling schematic device in an embodiment of the present invention, and referring to Fig. 2, the display present invention is mentioned
It, can high efficiency and safely reduction cell Bat for a kind of battery recycling device 100.Battery recycling device 100 is produced comprising a frequency
Raw device 10 and charge and discharge electric appliance 20.Frequency generator 10, sequentially to generate multiple frequency control signal Sv, frequency control signal
The frequency of Sv is belonging respectively to multiple frequency ranges (for example, frequency range R1, R2 shown in Fig. 3).Charge and discharge electric appliance 20, to electrical property
It is connected to electrode E1, E2 of battery, charge and discharge electric appliance 20 carries out charge and discharge to battery Bat according to the frequency of frequency control signal Sv.
According to the present invention, battery Bat can generate the relative motion between electrode E1, E2 in charge and discharge.For example, when charging,
It is mutually close between electrode E1, E2；It is mutually separate between electrode E1, E2 when electric discharge.In addition the frequency of charge and discharge controls, electrode E1, E2 can be made
It vibrates.The present invention can make the lead sulfate covered on electrode E1, E2, acceleration and the oxidation of sulfuric acid liquid are also by this vibration
Original reaction, can also make the crystalline texture of part be vibrated away from out electrode E1, E2, directly generate reduction reaction with sulfuric acid liquid, promote sulfuric acid
The specific gravity of liquid.In addition, all having its resonance frequency (Resonant because of electrode E1, E2 and the lead sulfate covered thereon
frequency).According to the dynamic characteristic of structure, the mode of oscillation (Vibration mode) of same resonance frequency flowering structure is
Fixed, i.e., the same fragile bad point of resonance frequency flowering structure is identical；But the different fragile bad points of resonance frequency flowering structure are different
's.Therefore, according to the frequency control signal of different frequency ranges, charge and discharge is carried out to battery, both can avoid because of single resonance
