Abstract
The utility model relates to a column shaped ionization cell comprising a shell, a core inside the shell, electrolyte in the core, a barrel shaped substance and a cover board. The barrel shaped substance is positioned in the central axis of the core. The cover board is sealed to the shell. A plurality of through holes is arranged on the side wall of the barrel shaped substance for filtering electrolyte. The utility model provides a column shaped ionization cell that can enable close contact between the positive plate and the negative plate isolated by the membrane and charge and discharge in fine performance.
Description
Technical field
The utility model relates to a kind of lithium ion battery, relates in particular to the column lithium ion battery that a kind of inside is placed with cylindric thing.
Background technology
The volume core of cylindrical lithium ion battery all is to make by the mode of reeling, also make the middle space that has certain diameter of volume core just because of coiling, the existence in space makes the volume in-core portion of cylindrical lithium ion battery contact not tight with negative plate by the positive plate that barrier film separates, and then influencing the performance performance of battery, the cycle performance and the consistency of battery are poor.A kind of column lithium ion battery in Chinese patent CN2743996 provides, thus the problems referred to above solved by the tubular article that is preserved for reeling at the volume in-core.But, because in the production technology of conventional batteries, need be still aging behind the battery liquid-filling, make electrolyte fully permeate, soak pole piece; After the ageing 24 hours, again with battery pre-charging, to activate lithium ion.Yet, because the existence of tubular article has brought new problem again: delayed electrolyte permeability, caused that ageing is insufficient, the battery pre-charging weak effect, thereby caused the charge-discharge performance of battery poor.
Summary of the invention
The purpose of this utility model provides a kind of positive plate that is separated by barrier film that can make and contacts with negative plate closely, can make the good column lithium ion battery of battery charging and discharging performance again.
Realize the technical scheme of above-mentioned purpose:
A kind of column lithium ion battery, comprise cylindrical shell, be contained in volume core, electrolyte, tubular article and the cover plate of infiltration in the volume core in the cylindrical shell, described tubular article is positioned on the central axis of volume core, cover plate covers and is sealed on the cylindrical shell, and the sidewall of described tubular article is provided with a plurality of through holes of being convenient to capillary electrolysis liquid.
Further, described tubular article is provided with axially open.
Described tubular article end is the gathering shape, and the end bore is less than tubular article middle part diameter of section.
Adopt technique scheme, the utility model beneficial technical effects is: owing to solved, the ageing insufficient battery charging and discharging performance poor technical problem that cause slow because of electrolyte permeability at a plurality of through holes of the sidewall setting of tubular article.The axially open that is provided with on the tubular article, and the end of gathering shape can make things convenient for tubular article to put into the volume core; Damage positive plate, negative plate or barrier film when avoiding inserting tubular article.

Embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:
A kind of column lithium ion battery as Fig. 1, Fig. 2 and shown in Figure 3, comprises cylindrical shell 1, is contained in volume core 2 in the cylindrical shell 1, electrolyte in volume core 2 of cover plate 3 and infiltration (among the figure not label).The inside of volume core 2 is placed with and supports volume core 2, prevents to roll up the tubular article 4 of core 2 distortion, the sidewall of this tubular article 4 is provided with a plurality of through hole 5 and axially opens 6 of being convenient to capillary electrolysis liquid, the end 7,7 ' of tubular article 4 is the gathering shape, be end 7,7 ' bore a less than tubular article 4 middle part diameter of section b, cover plate 3 covers and is sealed on the cylindrical shell 1.
As required, also can adopt Fig. 4 and tubular article 4 shown in Figure 5, not have axially open on this tubular article 4, other structure is identical with the structure of above-mentioned tubular article.
Claims (3)
1, a kind of column lithium ion battery, comprise cylindrical shell, be contained in volume core, electrolyte, tubular article and the cover plate of infiltration in the volume core in the cylindrical shell, described tubular article is positioned on the central axis of volume core, cover plate covers and is sealed on the cylindrical shell, it is characterized in that: the sidewall of described tubular article is provided with a plurality of through holes of being convenient to capillary electrolysis liquid.
2, column lithium ion battery as claimed in claim 1 is characterized in that: described tubular article is provided with axially open.
