 Hello everyone, my name is Huainan Xu, I'm a Ph.D. student, my advisor professor is Dr. Duyang Xu. What we are doing in my poster is we preload some lithium for lithium-M battery. Why we do that? Because the preloaded lithium will compensate the lithium loss so that we can increase the efficiency and the capacity of the battery. To be specified, a fresh made lithium-M battery is pretty much like you grab an empty bottle and a bowl full of water. You can consider the water inside is the lithium or the capacity of the battery. When charging the battery, it's like you pull the water from the bowl into the bottle. During this process, it is unavailable that you spill some water. Then, when you're using the battery, it's like you pull the water back into the bowl. You can see, due to the spillage, you have less water to pull back. That means the battery will lose some capacity during charging. Well, in our technique, we preloaded some lithium. That it is like we fill the empty bottle with some water in advance. Now, you can see, when you spill some water, the pre-filled water in the bottle will compensate that loss. Then, you have more water to pull back. That means you have more capacity when using the battery. We call this technique, preletiation. With preletiation, the lithium-M battery will have more capacity and more efficiency. Thank you very much.
