An all-solid-state battery (ASSB) is an energy storage device that replaces the flammable liquid or gel electrolytes found in conventional Lithium-ion batteries (or Li-ion batteries) with a solid electrolyte. This solid component\u2014typically composed of ceramics, sulfides, polymers, or oxides\u2014enables lithium ions to move between the anode and cathode while maintaining structural integrity.<\/p>\n
At its core, an all-solid-state battery shares the same fundamental purpose as a Li-ion battery: storing and releasing energy through the reversible movement of lithium ions between electrodes.<\/p>\n
However, as mentioned above, its architecture is different, which is essential for understanding the all-solid-state battery manufacturing process:<\/p>\n
1. Electrodes<\/strong><\/p>\n
Like conventional Li-ion batteries, all-solid-state batteries consist of an anode (negative electrode), and a cathode (positive electrode).<\/p>\n
In all-solid-state battery manufacturing, the cathode often employs high-capacity cathodes, such as lithium nickel manganese cobalt oxide (NMC). It is similar to those in Li-ion batteries.<\/p>\n
However, the materials and design of the anode differ:<\/p>\n
2. Electrolyte<\/strong><\/p>\n
The electrolyte is used in all-solid-state battery and conventional Li-ion battery manufacturing<\/a>. They are all used for conducting ions, but ASSBs starkly contrast with the liquid electrolytes used in conventional Li-ion batteries. Here\u2019s a breakdown of the key differences:<\/p>\n\n\n\n\n\n\n\n
