Problems solved by technology
[0004] The above method of realizing the gap will form a whole blank on the substrate, but cannot realize a regular square blank. In addition, the blank formed by the previous method will cause the slurry to tail, which will affect the performance of the lithium battery. At the same time, due to The large blank area will inevitably reduce the coating area, so that the coating slurry for charging and discharging functions in the unit volume space will be reduced, thereby reducing the storage capacity of the battery
