Although high-voltage lithium battery materials are getting more and more attention, these high-voltage anode materials are still unable to achieve good results in practical production and application. The biggest limiting factor is that the electrochemical stability window of the carbonate-based electrolyte is low. When the battery voltage reaches about 4．5（vs．Li/Li＋）, the electrolyte begins to p...

One-Step Pressing, it is rolling only once to achieve the designed thickness and density of the battery electrode. Two-Step Pressing, it is rolling the battery electrode to a certain thickness (such as 90μm) at first time, and achieve the designed thickness (such as 70μm) and desired density through the second time pressing. The main purpose of the rolling press is to control the electrode in the ...

The inconsistency of energy storage batteries mainly refers to the inconsistency of parameters such as battery capacity, internal resistance, and temperature. Our daily experience is that when two dry batteries are connected in positive and negative directions, the flashlight will light up, and we don’t consider consistency. However, once batteries are used on a large scale in energy storage syste...
