Spacer-containing electrode structure and its application to high energy density and fast chargeable lithium ion batteries

摘要

The present invention relates to a negative electrode including a negative electrode active material layer having a basis weight greater than 60 g / m 2 on a negative electrode current collector, and a positive electrode including a positive electrode active material layer having a basis weight greater than 100 g / m 2 on the positive electrode current collector. And an electrolyte containing an imide anion lithium salt and LiPO2F2, and at least one of the negative electrode active material layer and the positive electrode active material layer includes a spacer made of hard carbon. I will provide a.
