Description
Technical field
The utility model belongs to supercapacitor technologies field, and in particular to a kind of anode of ultracapacitor draws knot
Structure.
Background technology
Ultracapacitor is a kind of novel specific components between battery and traditional capacitor, has the charging time
It is short, service life is long, good temp characteristic, it is energy saving and environmentally protective the features such as.It is produced in Automatic meter reading system, consumer electronics
The industries such as product, regenerative resource, electric vehicle and hybrid vehicle and uninterruptible power supply (UPS) are widely used.
Existing supercapacitor positive electrode deriving structure majority is to wrap after welding flow collection sheet enters shell to carry out roller groove structure in core,
Its structural instability, anti-shake performance is poor, easily causes mechanical failure；And it is not close due to contacting, it easily causes electric under high current
Current density is uneven, and internal resistance is larger and unstable, the easy local pyrexia of charge and discharge process.
Utility model content
The purpose of this utility model is to provide a kind of anode deriving structures of ultracapacitor, overcome existing super
Capacitor anode deriving structure leads to that current density is uneven, local pyrexia is serious and internal resistance is larger since Mechanical Contact is bad
The shortcomings that.
Technical solution is used by the utility model：A kind of anode deriving structure of ultracapacitor, including core packet, just
Flow collection sheet and housing, an end face and the positive flow collection sheet of core packet weld, and side of the positive flow collection sheet far from core packet has multiple protrusions,
Housing wraps up core packet and positive flow collection sheet, and the housing end cap opposite with positive flow collection sheet is equipped with the housing welded with multiple protrusions
Pad cavity.
The utility model is also characterized by
Housing is provided with the protrusion for placing positive terminal at the end cap of positive flow collection sheet, and positive flow collection sheet, which is equipped with, makes positive terminal
The through-hole passed through.
The side wall of housing is provided with anti-explosion groove.
It is carved on positive flow collection sheet and is equipped with multiple positive flow collection sheet cavities.
The side far from core packet is provided with the positive flow collection sheet pad of multiple recess on positive flow collection sheet.
Core packet is wound into cylindric be made by aluminium foil and coated in the active material layer on aluminium foil.
A kind of anode deriving structure of ultracapacitor of the utility model overcomes existing supercapacitor positive electrode and draws
Structure leads to the shortcomings that current density is uneven, local pyrexia is serious and internal resistance is larger since Mechanical Contact is bad.This practicality
A kind of anode collection piece of the anode deriving structure of novel ultracapacitor is directly welded on housing, and core packet is welded with positive flow collection sheet
It connects, realizes that core packet is integrated with housing, positive terminal extraction is without Mechanical Contact, so as to eliminate the looseness of Mechanical Contact, favorably
In the performance for promoting ultracapacitor.
