A thick and dense electrode using an active material sintered disk is expected to have a high capacity because the volume of the active material is 100% in the cathode. This study focused on LiCoO 2, the most well-known active material for the cathode, to improve the properties of the sintered cathode.
Solid-state lithium batteries fabricated with LLTO-based composite solid electrolytes deliver a high discharge capacity at room temperature. Solid-state batteries have the potential for higher energy densities and enhanced safety when compared to conventional lithium-ion batteries.
In addition to the potential for composite fabrication, cold sintering could enable recycling of spent battery materials. Eliminating the need for high-temperature processing and the use of solvents to decompose materials into recoverable compounds is advantageous.
Moreover, in the case of the co-sintered solid-state battery, the excess Li is added to the electrolyte to prevent Li-loss during sintering at high temperatures. Thus, more precise tuning of the amount of excess Li in LiCoO 2 for the cathode of the co-sintered solid-state battery will be strongly required to realize the high-performance battery.
These results show that excess Li affects the electrode properties of the LiCoO 2 sintered cathode, and this tendency can be explained by the increase in Li-ion conduction through the LiCoO 2 sintered disk. This means it is a crucial design factor when the LiCoO 2 sintered cathode is applied to the Li-ion battery.
