Secondary battery electrode, and method for producing same
摘要
說(shuō)明書
As an example, the bulk may mean that it has a size of at least one dimension (width, length, or breadth) more than the designed thickness, based on at least a designed thickness of the active material layer of the electrode to be desired. More specifically, the bulk may mean that the size of one dimension of the three-dimensional body along at least one axis is at least 5 times, and substantially 10 times or more the thickness of the active material region of the electrode to be produced, based on three axes orthogonal to each other. In addition, the bulk may mean that each dimension of the three-dimensional body according to each of other two axes has a size corresponding to or more than a width or length of the active material region of the electrode to be produced, but is not necessarily limited thereto.
As an example, in terms of not a size but a mass, the bulk may mean a three-dimensional body having at least a weight more than the designed weight, based on a designed weight of the active material layer of the electrode to be desired. More specifically the bulk may mean a three-dimensional body having a weight of 10 times or more, and substantially 50 times or more the designed weight (weight of one active material layer of the electrode to be desired), but is not necessarily limited thereto.
