Specific embodiment
Fig. 1 show with winding electrode assembly 12 battery list pond 10 positive sectional view, the battery list pond by
Selectively conductive material 22 surrounds.Fig. 2 shows battery list ponds 10 along the sectional view of section A-A.
Battery list pond 10 includes shell 14, and there is the electrode assembly 12 of anode 17 and cathode 18 to be contained in the shell
In.The electrode assembly 12 being contained in shell 14 includes positive electrode layer and positive electrode layer, and separating layer is embedded in.Electrode assembly
12 be being wound around or stacking herein.
Shell 14 is constituted as hard case (Hardcase) with the cylinder with polygonal basic side.This outer housing 14 is with shell
Body lid 16 is closed, which has connecting lead wire or terminal 21,23 to be connected electrically to the electrode layer of electrode assembly 12.
For this purpose, collector 20,25 is connect with the positive electrode layer of electrode assembly 12 and positive electrode layer and connecting lead wire 21,23 respectively.It is negative
Pole 18 additionally has lead wire insulation portion 24, which makes connecting lead wire 21 and case lid 16 insulate.Case lid

Thiophen it) is surrounded for example in the form of metal foil.The such structure of metal foil being made of herein selectively conductive material 22
At so that the metal foil is directly contacted with collector 20,25.Preferably, metal foil is by Poly(3-Decyl Thiophen) system
It makes.Therefore the metal foil extends between negative connecting lead wire and positive connecting lead wire 21,23.If negative connecting lead wire with
Voltage difference between positive connecting lead wire 21,23 is increased beyond critical limit voltage, then by selectively conductive material 22
The metal foil of manufacture becomes conductive and potential can flow through two electrodes.Overcharging simultaneously for battery list pond 10 can so be prevented
And it provides and effectively overcharges protection.If voltage difference declines, such as due to the end overcharged of charging, then by selectively leading again
The metal foil that the material 22 of electricity is constituted becomes non-conductive again and battery list pond 10 can operate normally.

In Fig. 1 and Fig. 2, the battery list pond 10 of Fig. 4 includes case lid 16, and the case lid is made by selectively conductive material 22
It makes.So if the voltage difference between positive electrode and negative electrode 17,18 is more than critical limit voltage, then selectively conductive material
Material 22, particularly poly- 3- decylthiophene become conductive and potential can flow out between positive electrode and negative electrode 17,18.If electric
Pressure difference declines again, such as due to the end overcharged of charging, then selectively conductive material 22 becomes insulation and electric power storage again
Chi Danchi 10 can be operated normally.
Fig. 5 shows the positive sectional view in battery list pond 10, in battery Dan Chizhong lead wire insulation portion 24 in case lid
It is manufactured between 16 and connecting lead wire 21 by selectively conductive material 22.
The battery list pond 10 of Fig. 5 corresponds essentially to the battery list pond 10 shown in Fig. 1, Fig. 3, Fig. 4.It is different from
Attached drawing before, lead wire insulation portion 24 is between case lid 16 and connecting lead wire 21,23 by selectively conductive material 22, spy
It is not poly- 3- decylthiophene manufacture.So if the voltage difference between connecting lead wire 21,23 is increased beyond critical limit electricity
Pressure, then selectively conductive material 22 becomes conductive and potential can flow out.If between connecting lead wire 21,23
Voltage difference descends below critical limit voltage again, then battery list pond 10 can operate normally again.
Fig. 6 shows the side cross-sectional view in battery list pond 10, in the core 26 of the battery Dan Chizhong electrode assembly 12
It is manufactured by selectively conductive material 22 and is connect with the electrode layer of electrode assembly 12.
Battery list shown in fig. 6 pond 10 corresponds essentially to the battery list pond 10 shown in fig. 1 and 2.It is different
The battery list pond 10 shown in fig. 1 and 2, electrode assembly 12 include core 26, and the core is by selectively conductive
Material 22 manufactures.Additionally, core 26 is connect via contact element 28 with the positive electrode layer of electrode assembly 12 and positive electrode layer,
The contact element is equally manufactured by selectively conductive material 22.If the voltage difference between positive electrode layer and positive electrode layer
Under the critical limit voltage in selectively conductive material 22, then core 26 and contact element 28 are nonconducting
And positive electrode layer and positive electrode layer are insulated.In contrast, if voltage difference between positive electrode layer and positive electrode layer
More than the critical limit voltage of selectively conductive material 22, then this selectively conductive material become it is conductive and
Potential between electrode layer can flow out.
