Abstract
The utility model relates to a rechargeable lithium battery which comprises a containing housing, wherein the same end side of the containing housing is provided with an anode and a cathode and has the configuration of two integrated AA batteries, and a rechargeable lithium battery unit is contained in the containing housing. The battery product of the utility model adopts the configuration of the two integrated AA batteries, and adopts the rechargeable lithium battery; therefore, the utility model has the advantages of portability, long hours of use and great reduction of total cost.
Description
Technical field
The utility model relates to a kind of chargeable lithium cell, particularly, relates to a kind of portable equipment that can be used for, as the chargeable RCR-V3 lithium battery of digital camera etc.
Background technology
Along with popularizing of big power consumption portable equipments such as digital camera, domestic to high power capacity, the demand of the portable battery of sufficient discharge is more and more higher, portable battery mainly is to portable, portable equipments such as cordless apparatus provide power supply, more common definition is that it is also included within the subtype that a large-scale type (may be operated by the main group group) drives down, as: kneetop computer.The subtype of above-mentioned model may be clock and watch or the reserve battery in the computer.And relatively large number battery is as 4 kilograms or the above portable battery that do not belong to, and typical now portable battery is about several hectograms, and the family of portable battery comprises primary cell and rechargeable battery (secondary cell).
All batteries are divided into following all kinds of basically: dry cell carbon-zinc or dry batteries, and alkaline Mn cell alkaline-battery more than is disposable battery manganese batteries, primarybatteries; Lithium battery lithium batteries, lead-acid battery lead batteries, chemical cell secondary cell nickel-cadmium cell (Ni-Cd) chemical batteries (secondary batteries), Ni-MH battery Ni-MH, lithium ion battery Li-ion, above-mentioned is rechargeable battery substantially; Other has fuel cell fuel cell, physical battery physical energy, and solar cell solar cell batteries etc. is uncommon battery variety.
Lithium ion battery has following characteristics: 1, high energy density; 2, high operating voltage; 3, memory-less effect; 4, have extended cycle life; 5, pollution-free; 6, in light weight; 7, self discharge is little.
Therefore be very suitable for digital camera according to the These characteristics lithium ion battery, but the supplying cell of existing Chang Xuan all is No. five common batteries, and general digital camera needs two joint AA batteries at least, it is No.5 cell, and because the required common batteries amount of the king-sized portable equipment of this class power consumption of digital camera is very big, therefore, when using the common batteries out using at present, carry a large amount of common batteries, and frequent the replacing, even just changed promptly do not had the electricity, caused very large trouble to the user.
In addition, use disposable battery, especially use disposable lithium ion battery etc., its cost is very high.
The utility model content
The purpose of this utility model is to provide a kind of chargeable RCR-V3 battery, it has adopted chargeable lithium ion battery, and will adopt the conjuncted configuration design of two joint No.5 cells, reduce and carry trouble, and service time is long, reduce and change the battery trouble, use chargeable mode, reduce use cost.
The technical solution of the utility model is as follows:
A kind of rechargeable lithium battary, it is a kind of RCR-V3 battery, comprises a ccontaining housing, the same distolateral both positive and negative polarity that is provided with of this ccontaining housing, it has the conjuncted profile of two joint AA batteries, and this ccontaining housing content is equipped with the rechargeable lithium battary unit.
Described lithium battery, wherein, described RCR-V3 battery is used for digital camera and replaces two joint AA batteries.
A kind of chargeable RCR-V3 battery that the utility model provides is designed to the conjuncted profile of two joint No.5 cells owing to adopted, and adopts chargeable lithium ion battery, and easy to carry, service time is long, and overall cost greatly reduces.
Description of drawings
In the accompanying drawing,
Fig. 1 and Fig. 2 are the front view and the vertical view of overall appearance of the present utility model;
Fig. 3 is a schematic cross section of the present utility model.
Embodiment
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and beneficial effect thereof apparent by detailed description to preferred embodiment of the present utility model.
A kind of chargeable RCR-V3 battery 100 of the present utility model, as Fig. 1, Fig. 2 and shown in Figure 3, it has adopted the conjuncted Cross section Design of two joint No.5 cells, it comprises a ccontaining housing 120, the cross sectional shape that has two joint No.5 cells in this putting part body section, its voltage and other electrically design also save the identical of No.5 cells with two, so just reduced the particle number of carrying, and, the utility model has adopted chargeable lithium ion battery material 110, its anodal main component is LiCoO2, negative pole is mainly carbon, anodal reaction during charging: LiCoO2Li1-xCoO2+xLi++xe-, negative reaction: C+xLi++xe-Clix, the back reaction of above-mentioned reaction takes place in battery overall reaction: LiCoO2+CLi1-xCoO2+Clix during discharge.Because its capacity is more than the common batteries height, and its discharge curve just descends suddenly when fast ends, so is particularly suitable for the portable equipment of big power consumption, as digital camera etc.
Should be understood that, concerning the those of ordinary skill of field, the change or the replacement that can be equal to according to the technical solution of the utility model, and all these changes or replace the protection range that all should belong to the utility model claims.
Claims (2)
1, a kind of rechargeable lithium battary is characterized in that, it is a kind of RCR-V3 battery, comprise a ccontaining housing, the same distolateral both positive and negative polarity that is provided with of this ccontaining housing, it has the conjuncted profile of two joint AA batteries, and this ccontaining housing content is equipped with the rechargeable lithium battary unit.
2, lithium battery according to claim 1 is characterized in that, described RCR-V3 battery is used for digital camera and replaces two joint AA batteries.
