How do you improve the energy density of lithium batteries by using more advanced production equipment?

Use more advanced production equipment in order to improve the consistency and reduce production fluctuations, thus to improve on the premise of minimum value without changing the mean value. What determines the quality of a batch of batteries is this minimum value increased. The following are two examples:

1, DangTu machine coated tolerance more hours, minimum volume/design capacity can be improved, if the customer is you have any requirement on the minimum capacity, that is equivalent to in the design at constant volume, raised the minimum capacity, that is to improve the capacity of the batteries of the evaluation to the customer; Is negative deviation lower coating at the same time, considering the efficiency for the first time, after cycle capacity attenuation factors, such as design negative excess can reduce moderately, thereby the battery have more positive electrode materials, also is equivalent to have more capacity.

2, as the accuracy of the roller mill increase, due to reduce the error of actual rolling compaction design can be more close to the material's biggest compaction, thus improve the design capacity and manufactured batteries capacity; More uniform rolling out the thickness of the sheet, this is equivalent to increase the consistency of the thickness of the batteries, which can choose smaller max THK - design THK when the design, so as to improve the design capacity (cutter width, tape width, let the ark accuracy, etc. Similarly, it is needless).
