Detailed Description
The present invention will be described in detail with reference to the following embodiments and drawings.
Example , referring to fig. 1, A high capacity polymer lithium battery, comprising a lithium battery body 1 and a reinforcing plate 4 attached to at least surfaces of the lithium battery body 1, wherein the lithium battery body 1 is a flexible package, the lithium battery body 1 has two tabs, i.e., a positive tab 2 and a negative tab 3, and the reinforcing plate 4 is a carbon fiber plate or a plastic plate.
Specifically, the reinforcing plate 4 may be non-porous carbon fiber sheets.
The reinforcing plate 4 is adhered to the lithium battery main body 1 by glue.
Example two, as shown in fig. 2, is substantially the same as example , except that the reinforcing plate 5 is carbon fiber frame plates provided with two large holes 5a, and the large holes 5a have a material reduction effect.
Example three, as shown in fig. 3, is substantially the same as example , except that the reinforcing plate 6 is carbon fiber mesh plates with uniformly distributed redundant pores 6a, and the pores 6a have the function of reducing materials and simultaneously dissipating heat.
The carbon fiber has light in weight, and the characteristics that hardness is big consequently adopt the carbon fiber to protect lithium cell 1, can support lithium cell 1 simultaneously, and lithium cell 1 can not bend, has consequently avoided operation or transportation in-process, and the condition of a small amount of dislocation takes place for inside lamination.
The utility model provides a gusset plate 4 still has light in weight, does not influence end use, installation and dismantlement all compare the aspect characteristics.
This effect can also be achieved by using a rigid plastic for the reinforcement plate 4.
The disclosure of the present invention is limited only by the preferred embodiments , and is not intended to limit the scope of the invention, which is defined by the following claims.
