Silicon-based all-solid-state batteries offer high energy density and safety but face significant application challenges due to the requirement of high external pressure. In this study, a Li 21 Si 5 /Si–Li 21 Si 5 double-layered anode is developed for all-solid-state batteries operating free from external pressure.
Silicon (Si) has emerged as a potent anode material for lithium-ion batteries (LIBs), but faces challenges like low electrical conductivity and significant volume changes during lithiation/delithiation, leading to material pulverization and capacity degradation.
Si-based all-solid-state batteries face application challenges due to the requirement of high external pressure. Here, authors prepare a double-layered Si-based electrode by cold-pressing and electrochemical sintering that enables all-solid-state batteries operating free from external pressure.
Single-crystal material with integrated particles possesses the characteristic of unidirectional contraction/expansion, which can alleviate the anisotropic lattice strain of primary particles during deep charge-discharge processes, thereby significantly improving structural stability of cathode materials , , .
However, back grinding during the chip fabrication generally results in ≈70% of single-crystal SiC being wasted, leading to the high cost of SiC chips. In order to improve the utilization, single-crystal SiC on polycrystal SiC (SoP-SiC) is bonded.
