AI Technical Summary
Conventional lithium-ion batteries face issues such as capacity fade during cycle life and safety risks due to liquid electrolytes, while solid-state batteries with solid electrolytes suffer from high manufacturing costs and time-consuming processes like discharge plasma sintering and pressure activation, and pouch cells require complex manufacturing processes that increase cost and time.
A solid-state battery design comprising a cathode with Li ions, graphene, and optionally a binder, an electrolyte, and an anode, preferably a lithium anode, where the electrolyte is disposed between the cathode and the anode, eliminating the need for costly manufacturing processes by using graphene to enhance interfacial resistance and capacity retention.
The battery achieves high-capacity cycle stability, retaining at least 60% of its original capacity after 150 cycles, significantly outperforming conventional solid-state batteries, and allows for the production of larger-sized pouch cells without complex manufacturing processes.
