Production method of negative electrode material for lithium battery
CHAPTER 3 LITHIUM-ION BATTERIES
(LCO) was first proposed as a high energy density positive electrode material [4]. Motivated by this discovery, a prototype cell was made using a carbon- based negative electrode and LCO as the positive electrode. The stability of the positive and negative electrodes provided a promising future for manufacturing.
In addition, the lower discharge platform (0.1 V) helps to avoid the formation of lithium dendrites on the electrode surface. However, silicon negative electrode materials suffer from serious volume effect (∼300%) in the Li-ion charge-discharge process, leading to subsequent pulverization of silicon [3,11,13].
