Lithium-ion batteries, used in EVs today, have a liquid electrolyte solution sandwiched in between their cathodes and anodes. Alternatively, solid state batteries use solid electrolytes. The
For these reasons, in both liquid- and solid-state Li-metal batteries, there is a growing interest in "Li-free" (or anode-free) manufacturing 9,10,11,12, in which the battery is fabricated in
When charged to 2.8 V, the Li 2 S@Co-C@MHF with 2.0 mg cm −2 Li 2 S loading exhibits a long and flat plateau, delivering a high capacity of 805 mAh g −1 in SPE (fig. S20A). Two voltage plateaus still appear at ca. 2.3 and 2.0 V upon discharge, revealing a similar LiPS-intermediated redox pathway with that in LEs.

The inclusion of a Mg–Bi-based interlayer between the lithium metal and solid electrolyte and a F-rich interlayer on the cathode improves the stability and
By: Sept. 23, 2021--Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense.
The safety of a solid lithium battery has generally been taken for granted due to the nonflammability and strength of SEs. However, recent results have shown the
Anode-free solid-state lithium batteries are promising for next-generation energy storage systems, especially the mobile sectors, due to their enhanced energy density, improved safety, and extended calendar life. However, the inefficiency of lithium plating and stripping leads to rapid capacity degradation due to the absence of excess

Although the current industry is focused on lithium-ion, there is a shift into solid-state battery design. "Lithium-ion, having been first invented and commercialized in the 90s, has, by and large, stayed the same," said Doug Campbell, CEO and co-founder of Solid Power, Inc. "You pretty much have the same electrode combinations with some
Furthermore, the tension induced at the interface between the electrode and the electrolyte interface as a product of constant contact with the solid electrolyte reduces the battery''s durability at room temperature (300 K) [13], [44].The Li-based solid-state battery is revealed schematically in Fig. (1).The curving arrows represent the
