The purpose of this utility model is achieved in that
A kind of secondary lithium battery that the utility model provides comprises positive plate, negative plate, barrier film, electrolyte and can; It is characterized in that: also comprise a security component, this security component is an elastic plate, and this elastic plate is installed between the pole piece group that battery case inwall and positive plate, barrier film, negative plate be superimposed as.
A kind of secondary lithium battery group that the utility model provides, comprise battery pack and can that the single battery structure be made up of positive plate, barrier film, negative plate and electrolyte is superimposed as: it is characterized in that: also comprise a security component, this security component is an elastic plate, described elastic plate is installed between the battery pack and shell that single battery is superimposed as, and perhaps described elastic plate is installed between the batteries in battery set.
In above-mentioned technical scheme, described elastic plate is the plate that an elastomeric material is made, and its surface has the plate of ridge design, perhaps is one to have the plate of curved surface; Perhaps for tabular elastomer or be one the band spring pressing plate; Stainless steel for example.
In above-mentioned technical scheme, also comprise a security component, described security component is that a sealing is installed in the unidirectional gas bleeder valve on the battery container, this unidirectional gas bleeder valve is a side cylinder with holes, be with the sleeve pipe (as the valve of bicycle) of elastomeric material on its cylinder, when air pressure inside became too big, battery/battery pack internal gas was released, and extraneous gas can't enter in the battery case or the shell of battery pack in.
The elastomeric material of the sleeve pipe of described relief valve (as the valve inside of bicycle) is selected from: fluorubber, ethylene-propylene rubber, ethylene-propylene diene copolymer elastomeric material.
Advantage of the present utility model:
1. because in the shell of battery or the horizontal frontal plane of the maximum in the shell of battery pack, assemble the pressing plate of a figuratum elastic plate/tabular elastomer/band spring etc., make battery pole piece in the charge/discharge process, be subjected to the elastic force effect all the time, just guaranteed/keep stable dynamically being close between negative plate and barrier film, guaranteed that the internal resistance dynamic stability of battery and the orientation of lithium ion move.
2. when assembling, the liquid lithium ionic cell group also adopts elastic plate or elastomeric material, be installed between maximum horizontal frontal plane of battery pack and the outer casing inner wall, adopt elastic plate constantly each battery in the battery pack to be applied the elastic force effect, therefore can do liquid lithium ionic cell with flexible package, this structure can guarantee to be close between battery pole piece and the barrier film, all use high-intensity shell without each battery, greatly reduce manufacturing cost.
3. the utility model is taked gas bleeder valve of assembling on the shell of battery/battery pack, has only the side with holes on the cylinder of this gas bleeder valve, therefore can only unidirectionally lose heart; Put the sleeve pipe that an elastomeric material is made again outside circle, when air pressure inside became too big, battery/battery pack internal gas was released but extraneous gas can't enter in the shell, has guaranteed the fail safe of battery/battery pack.
