Technical field
The utility model relates to technical field of lithium ion, and in particular to a kind of high-capacity battery.
Background technique
High capacity great current cell is applied to the neck such as portable high-performance electric power driven tools, digital product, electric car, energy storage
When domain, currently, the method for improving energy density mainly has: first is that material capacity is improved, using nickelic new material, high voltage material
Material, but this technique is immature, it is at high cost；Second is that PACK lightweight, densification, but due between the PACK battery core after compact
Shell has two layers (shell accommodates a battery core, and adjacent battery core is spaced two layers of shell wall), and heat dissipation is slow, connects between battery
Part is unstable.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of high-capacity battery and its production methods, can
It is at low cost to greatly improve battery energy density, battery core heat is passed to simultaneously by the fixed battery core of protrusion by shell, accelerates heat dissipation.
Purpose of the utility model is realized as follows:
A kind of high-capacity battery, including shell, cover board and several naked battery cores, before corresponding to each naked battery core in the shell
Two sides and bottom are equipped with protrusion afterwards, are equipped with anode ear and negative electrode lug at the top of the naked battery core, the cover board lower end correspond to anode ear,
Negative electrode lug is respectively equipped with anode confluence piece, cathode confluence piece.
Preferably, explosion-proof valve and liquid injection hole are additionally provided on the cover board.
Preferably, there are gaps between the two neighboring naked battery core.
Preferably, the area summation of the contact area between the protrusion and naked battery core and naked battery core front and rear sides and bottom
It is equal.
Preferably, the protrusion is latticed.
Preferably, area summation of the contact area between the protrusion and naked battery core than naked battery core front and rear sides and bottom
It is small.
Preferably, the corresponding anode confluence piece in the cover board upper end, cathode confluence piece are respectively equipped with positive terminal, negative terminal.
The beneficial effects of the utility model are:
1, battery energy density can be greatly improved；
2, it can be convenient battery modules PACK, battery group coherence request is low；
3, all batteries in use, pass through the electric current of each independent battery core, voltage, local environment in the battery
(either outside batteries or inside battery) are all identical, greatly improve battery performance；
4, at low cost, material cost is greatly reduced using the battery of the structure.

Specific embodiment
Referring to figures 1-3, the utility model relates to a kind of high-capacity batteries, including shell 1, cover board 2 and several naked battery cores
3, the front and rear sides and bottom that each naked battery core 3 is corresponded in the shell 1 are equipped with protrusion 4, are equipped with anode at the top of the naked battery core 3
Ear 5 and negative electrode lug 6,2 lower end of cover board corresponds to anode ear 5, negative electrode lug 6 is respectively equipped with anode confluence piece 7, cathode confluence piece 8.
Described raised 4 have good thermal conductivity and insulating properties, while fixing naked battery core, battery core heat are passed to shell, then fastly
Speed heat dissipation.
Explosion-proof valve 9 and liquid injection hole 10 are additionally provided on the cover board 2.
There are gaps between the two neighboring naked battery core 3.Keep inside battery heat-dissipating space big.
The area summation phase of contact area and naked 3 front and rear sides of battery core and bottom between described raised 4 and naked battery core 3
Deng.Described raised 4 be latticed.Keep naked battery core more firm in shell, heat dissipation performance is more preferable.
Contact area between described raised 4 and naked battery core 3 is smaller than the area summation of naked 3 front and rear sides of battery core and bottom.
The corresponding anode confluence piece 7 in 2 upper end of cover board, cathode confluence piece 8 are respectively equipped with positive terminal 11, negative terminal 12.
A kind of production method of high-capacity battery, using above-mentioned battery, production stage is as follows:
Step 1: by the corresponding positive and negative confluence on piece for being welded on cover board of the positive and negative tab of several naked battery cores；
Step 2: each naked battery core is put into the intracorporal protrusion of shell, shell is fitted closely with naked battery core；
Step 3: laser seal between cover board and shell, toasts fluid injection.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
