Description
Technical field
The utility model provides a kind of tubular type great-capacity power battery, belongs to power accumulator technical field.
Background technology
Lead-acid battery has had the history of 130 years, has dependable performance, mature production technology, compared with Ni-MH battery and lithium electricity
Pond low cost and other advantages.The current electric bicycle overwhelming majority is to use sealing-type lead-acid battery.Sealing-type lead-acid battery is
Positive and negative pole plate interfolded is arranged in battery case, isolated between positive and negative pole plate with insulating barrier, when electrolyte fills
Enter in battery case, electrolyte is chemically reacted with the lead on positive and negative pole plate.When battery charges, become the positive and negative of lead sulfate
Lead on two-plate is discharged into the sulfuric acid components being fixed therein in electrolyte, respectively becomes lead and lead oxide, makes electrolyte
In sulfuric acid concentration be continuously increased, voltage rise, put aside energy；During electric discharge, the lead on lead oxide and negative plate in positive plate
Reacted with the sulfuric acid in electrolyte and become lead sulfate, the sulfuric acid concentration in electrolyte is constantly reduced, voltage declines so that
Energy reduces, and battery externally exports energy, therefore the process that the cycle charge-discharge of battery, which is electric energy and chemical energy, constantly to be changed,
The final storage and release for realizing energy.
Positive plate entangles rib with comb, and the inside pours into lead oxide powder, and negative plate is common grid type plate, this
Sample is referred to as tubalar type lead acid battery.Because the active material of positive plate is inside pipe, it is not easy to come off, so long lifespan, still
Its active material and electrolyte contacts area are few, and utilization rate is lower than paste spread type.So its high-rate performance is bad, it is typically used as
Traction battery.
The content of the invention
To solve the above problems, the utility model provides a kind of tubular type great-capacity power battery, concrete scheme is：
A kind of tubular type great-capacity power battery, including battery case, the battery case is interior to be provided with electrode assembly, the electrode assembly bag
Include the carrier ring of polylith closed assembly, bonding connection between adjacent separator layer；The two sides of the carrier ring are provided with the appearance being interspersed
Groove is put, positive pole unit or negative pole unit are provided with storage tank；The positive pole unit includes positive pole rib and positive active material,
The negative pole unit includes negative pole rib and negative electrode active material, and positive pole unit and negative pole unit are located at carrier ring the same side respectively
Storage tank in；The positive pole unit and negative pole unit of adjacent separator layer are staggered；The top and bottom difference of the storage tank
Encapsulated by top plate and bottom plate, the both sides of the electrode assembly are encapsulated by side plate；The positive pole rib and negative pole rib of same carrier ring
Be connected respectively with upper collector plate and next part flowing plate, the upper collector plate and next part flowing plate of polylith carrier ring again respectively with anode collection plate
Connected with negative pole currect collecting plate.
Further, the carrier ring is glass mat.
Further, the storage tank is rectangular channel.
Further, the thickness of the carrier ring is 3~5mm.
Further, the groove width of the storage tank is 1~2mm.
Further, the outside of the electrode assembly is provided with three layers of reinforcing frame of upper, middle and lower.
Beneficial point of the present utility model is：Tubular type great-capacity power battery in this programme utilizes the dividing plate with storage tank
Layer composition electrode assembly, after carrier ring closed assembly, storage tank forms the cavity of closing, and positive active material and negative electrode active are staggeredly filled
In in storage tank, both the active material with tubular cells is difficult for drop-off the advantages of, while add active material and electrolyte
The area of contact, its high-rate performance can be improved.
