Surface and an outer surface, the inner surface or/and the outer surface be equipped at least eight resilient projections, the resilient projection its
In 4 four ends for being arranged on the inner surface, other 4 of the resilient projection four ends for being arranged on the outer surface
Portion.
Preferably, at least two battery core is attached by serial or parallel connection.
Preferably, the resilient projection is spaced apart and arranged in the inner surface or/and the outer surface.
Preferably, the resilient projection is covered with the inner surface or/and the outer surface.
Preferably, the resilient projection is square, rectangle or circle.
Preferably, the resilient projection is in polyline shaped.
Preferably, the resilient projection is in " Z " font.
Preferably, the thickness of the protective layer is 0.1mm ~ 2mm.

The utility model additionally provides a kind of lithium battery, and the lithium battery pack contains above-mentioned battery core group.
Compared with prior art, the battery core group of the utility model includes protective layer, in the inner surface or/and appearance of protective layer
Face is equipped at least eight resilient projections, and wherein 4 four ends for being arranged on inner surface of resilient projection, resilient projection is in addition
4 four ends for being arranged on outer surface can be very good using the cushion performance of resilient projection between protection battery core and battery core
Collision, also using resilient projection protective layer with battery core is not contacted directly, by the weight of bigger or is touched in battery core
When hitting, battery core first squeezes resilient projection, and when stress is more than the support force of resilient projection, battery core just touches protective layer, a side
Face can reduce the impact force of protective layer, and another aspect protective layer also is able to carry out second protection to battery core to prevent battery core and electricity
Core collides, and therefore, battery core group can bear the impact force of bigger without so that being damaged between battery core and battery core.

Fig. 1 is the structure diagram of the battery core group of the utility model.
Fig. 2 be the utility model battery core group in protective layer a kind of structure diagram.
Fig. 3 be the utility model battery core group in resilient projection a kind of structure diagram.
Specific embodiment
For the technology contents that the present invention will be described in detail, construction feature, the effect realized, below in conjunction with embodiment and coordinate
Attached drawing is explained in detail.
It please referring to Fig.1, the battery core group 100 of the utility model includes 20 and at least two battery core 10 of protective layer, and at least two
Battery core 10 is connected with each other, and protective layer 20 is set between adjacent battery core 10, and protective layer 20 has an inner surface and an outer surface, interior
Surface or/and outer surface are equipped at least eight resilient projections 21, wherein 4 four ends for being arranged on inner surface of resilient projection 21
Portion, other 4 four ends for being arranged on outer surface of resilient projection 21.In one embodiment, battery core 10 there are two setting,
Mode in parallel or series may be used between battery core 10 and battery core 10, anode 11 and cathode 13, two electricity are set in battery core 10
Protective layer 20 is equipped between core 10, the preparation of elastic material may be used in protective layer 20, has certain cushioning effect, to battery core
10 shield, and the thickness of protective layer 20 is 0.1mm ~ 2mm, specifically, the thickness of protective layer 20 can be 0.1mm,
0.5mm、1mm、1.5mm、2mm；The thickness of resilient projection 21 is 0.01mm ~ 1mm, and specifically, the thickness of resilient projection 21 can be with
