Solid-state lithium metal batteries (SSLMBs) have been widely predicted as an “enabler” for the next-generation high-energy-d. batteries. To perform this goal, both solid electrolytes (SEs) and metallic Li anodes are the keys. Li-rich garnet SEs exhibit many unique advantages for enabling SSLMBs, such as high Li-ion conductivity, superior mech., chem. and electrochem. properties. However, the garnet-based SSLMBs suffer from intractable interfacial problems including poor-contact-induced high interfacial impedance and dendrite-induced fast short circuit, which greatly hinder their practical application. In this work, a facile and low-cost artificial interface engineering is proposed to improve Li/SEs interface. Benefitted from the superior wettability of isopropanol InCl3 solution on the Li6.4La3Zr1.4Ta0.6O12 (LLZTO) surface, a homogeneous and tightly-adhering lithiophilic interface consisting of InLix and LiCl is efficiently constructed. As a result, the interface impedance was decreased from 189 to 10 Ω, and the critical c.d. for the LLZTO is increased from 0.2 mA cm-2 to 0.7 mA cm-2. The Li/Li sym. cells can work stably above 4000 h at a c.d. of 0.2 mA cm-2. At a higher c.d. of 0.45 mA cm-2, no obvious dendritic Li proliferation and interfacial contact failure is observed after cycling for more than 1000 h. The full cells with LiFePO4 as cathode exhibit a superior electrochem. performance with a reversible capacity of 127 mAh g-1 at 0.5 C after 475 cycles, and a rate capability of 101 mAh g-1 at 1 C. This effective, simple and economical wet-chem. strategy for constructing Li/SEs artificial interface may provide an alternative route for solve the interfacial issues of other SSLMBs. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Name: Lithium chloride).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Name: Lithium chloride
