And realizing inside pole piece A4 the short circuit between positive/negative collector at first, the quantity of heat production of this kind of short-circuit conditions is minimum, is almost multiple
The 1/10～1/3 of miscellaneous internal short-circuit heat, heat production speed simultaneously is relatively low, and can increase the heat radiation time of battery, again
Heat during battery exception is reduced.By the short circuit between the most positive/negative collector, by inside battery major part energy expenditure
After falling, battery just can proceed to pole piece other various complicated short-circuit conditions internal, but now due to energy content of battery major part
Being consumed, the heat that therefore other short-circuit conditions produces is the most less, thus it is overheated, on fire, quick-fried to reduce battery to greatest extent
Fried risk.
It addition, the conducting state of the outmost turns negative current collector of the conductive layer 21 and pole piece A4 of positive pole short-circuit protection assembly 2
One end time can be continued, as it is shown on figure 3, and owing to the other end of this conductive layer 21 is free end, therefore this free end can be with
While abnormal foreign object 9 gos deep into inside battery and tilt, eventual failure, i.e. this fracture process need certain time so that
The short-circuit condition certain time of this positive pole short-circuit protection assembly 2, consumes the energy of major part battery, significantly provides electricity
The security performance in pond.
Meanwhile, the short path principle of the short-circuit protection assembly on other pole piece (such as pole piece B5, pole piece C6) is also similar to, herein
Repeat no more.
Inside battery is goed deep into further, as it is shown on figure 3, eventually result in battery case 1 and pole piece along with abnormal foreign object 9
The conductive layer 21 of the positive pole short-circuit protection assembly 2 on A4 contacts and turns on, and now the heat dissipation path of inside battery is: collector-
Conductive layer-the shell of short-circuit protection assembly, heat dissipation path shortens further, and it is good to be heat conductivility in this heat dissipation path
Material, when making battery exception, internal heat dissipating is faster, thus increases battery safety under the conditions of exceedingly odious use further
Energy.
To sum up, the lithium ion battery that the present invention provides, by arranging a short-circuit protection group on the pole piece of inside battery
Part, battery, when by external force generation abnormal deformation, can actively make internal short-circuit of battery, and make the complicated short-circuit conditions within pole piece
The large area short circuit being converted between positive/negative collector, can make internal short-circuit of battery heat be reduced to minimum, can shorten simultaneously
Heat conduction path, i.e. also increases the heat radiation time of battery while the battery heat production speed that slows down, thus increases battery badly
Safety and reliability under the conditions of use.And the lithium ion battery that the present invention provides, when normally using, battery can be accelerated
Heat radiation, beneficially inside battery heat balance.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Any amendment, equivalent and the improvement etc. made within god and principle, should be included within the scope of the present invention.
