Silicon-based all-solid-state batteries (Si-based ASSBs) are recognized as the most promising alternatives to lithium-based (Li-based) ASSBs due to their low-cost, high-energy density, and reliable safety.
In addition, the thin-film batteries are also applied to MEMS, and large-scale batteries (e.g., pouch batteries, cylindrical batteries) are applied to high-energy and high-power systems, such as EVs, which face greater challenges at present.
To achieve a higher energy density of batteries, layered transition metal oxides of cathodes with high Ni-content have been developed (e.g., LiNi 0.8 Co 0.1 Mn 0.1 O 2 or LiNi 0.9 Co 0.05 Mn 0.05 O 2, denoted as NCM), which possess high specific energy capacity (200–250 mAh g −1) and relatively high operating voltage (∼4.3 V vs. Li + /Li) .
Furthermore, Si-based all-solid-state full batteries with various designs (e.g., thin-film or micro battery and pouch battery) are anticipated to cater to diverse applications, such as micro-batteries for micro-electro-mechanical system (MEMS), and pouch batteries for 3C electronic products, EVs, etc. [29, 30, , , , ].
In 1999, Neudecker et al. firstly employed silicon tin oxynitride (SiTON) anode and lithium phosphorus oxynitride (LiPON) electrolyte into a thin-film battery, which maintained a high capacity .
And when the target of the energy density of Si||ASSE||NCM full-cells was set as 300 Wh kg −1, the corresponding thickness of LLZO, LPSCl, and PEO ASSEs should be less than 23, 74, and 92 μm, respectively. Therefore, decreasing the thickness of ASSEs is confirmed to be an effective method to further improve the energy density of full batteries.
