Description

A kind of electrokinetic cell
Technical field
The utility model belongs to a kind of lead acid accumulator, the lead acid accumulator in the source that particularly is used as power.
Background technology
What the common electrokinetic cell overwhelming majority adopted all is the pasting plate battery, and it comprises positive plate plate, negative plate, dividing plate, pole, battery case and battery cover etc.
Common power with valve-control sealed battery owing to adopt dull and stereotyped pole plate, and dull and stereotyped pole plate adopts gravity casting, for fine shaping, grid can not be done very thinly, and general weight is bigger, and grainiess is poor, easily corrosion, thereby cause defectives such as the battery specific energy is low, cycle life is short, heavy-current discharge performance is relatively poor, be difficult to satisfy the present user instructions for use growing electrokinetic cell; Besides, blow-by between the existing battery cell, there is the space, cause climbing between cell negative terminal acid or short circuit easily and make the battery premature failure, and the battery anti-seismic performance is bad, easily utmost point group's slippage or dislocation taking place when using and makes battery failure under long-term vibration or some adverse circumstances, and the easy leakage of battery, these have all greatly limited the development of electric bicycle, electric automobile and other hybrid electric vehicles.
Summary of the invention
The utility model will solve the problem that existing electrokinetic cell shock resistance is poor, specific energy is low, heavy-current discharge performance is poor, useful life is short, provides a kind of electrokinetic cell of the present utility model, to solve described problem.
For addressing the above problem, the technical solution adopted in the utility model comprises battery case and battery cover, its special character is to be filled with the wax layer between cell negative terminal, between battery electrode group and battery cover, be filled with the wax layer, flatly be provided with the bipolar pole plate that comprises positive plate part and negative plate part in the battery case.
Described bipolar pole plate has plumbous cloth grid, a plumbous cloth grid part is coated with anode diachylon and constitutes described positive plate part, plumbous cloth grid another part is coated with cathode lead plaster and constitutes described negative plate part, the alternate distance with the negative plate part of positive plate part on plumbous cloth grid.
Described plumbous cloth grid should adopt the compound spongy lead braiding of glass fibre to form, and its inner core of the compound spongy lead of described glass fibre has glass fiber, at the peripheral plating of glass fiber the Pb-Sn alloy cladding layer is arranged.
Have good adhesion for making between the described plumbous fabric swatch aperture plate lattice node, prevent plumbous cloth distortion and extension, have a Pb-Sn alloy-layer can satisfy this requirement in this plumbous cloth grid surface-coated.
The compound spongy lead of described glass fibre is to push the plating layer of lead-tin alloy outside glass fiber strand, be drawn into diameter again and be the spongy lead about 0.4mm, it has higher intensity and corrosion resistance and good electrical conductivity, and in light weight, can greatly improve the useful life and the rapid charge characteristic of specific energy, specific power and the battery of battery as the grid material of battery with it.
The utility model is owing to be filled with the wax layer between the cell negative terminal and between battery case and the battery cover, so the battery anti-seismic performance is good, and battery is not prone to leakage, single compartment is difficult for producing climbs acid or short circuit, be not prone to self discharge, the corrosion resistance of parts such as battery bus-bar also is improved, and battery is prolonged useful life; Because the utility model adopts the horizontal double pole pole plate, single compartment electron conduction approach shortens again, so the internal resistance of cell reduces, the high-rate battery discharge performance is improved; Adopt the utility model of plumbous cloth grid, the weight of battery pole plates, volume reduce, and battery specific energy, specific power are improved.Electrokinetic cell of the present utility model, after testing, its combination property is improved largely than common electrokinetic cell, and only specific energy is just brought up to 40Wh/kg (2 hour rate) by the 32Wh/kg (2 hour rate) of common batteries, improves more than 25%.
