Abstract
In the present paper, the results of the theoretical investigation of the small lithium-chloride clusters are reported. The geometrical structures, electronic and thermodynamic stability of superalkalis, superhalogens, and their single and double charged ions are obtained using efficient and accurate quantum chemistry methods. Further, low-lying isomers of the Lin Cln ( n = 2 - 5 ) clusters and their stability parameters are calculated. Two ways of formation of the Lin Cln clusters, polymerization of LiCl fragments and combination of superalkalis and superhalogen clusters, are compared. By examination the lattice energy and the average Li-Cl bond length in rectangular Lin Cln ( n ≤ 60 ) clusters, it was concluded that already 50 LiCl are enough to mostly resembles the structure and stability of the bulk LiCl.

Abstract
Anti-perovskite type Li2 OHCl was previously studied as a solid-state Li+ conductor. Here, we report that the Li2 OHCl can be electrolyzed at 3.3 V or 4.0 V, with the creation of O2 /HCl gases and the release of 2 equiv. Li+ via two different decomposition routes, depending on the acidity of electrolyte. In the electrolyte with trace acid, the Li2 OHCl is oxidized at a constant voltage of 3.3 V. In neutral electrolyte, the oxidization of Li2 OHCl starts at 4.0 V, but the produced HCl will increase the acidity of electrolyte and lead to a voltage drop to 3.3 V for the electrolysis of Li2 OHCl. The electrolysis of Li2 OHCl delivers a lithium releasing capacity as high as 810 mAh g-1 , with an equivalent Li-deposition or Li-intercalation on anode, making it a promising candidate as a Li reservoir for prelithiation of anode. Using Li2 OHCl as the lithium source, silicon-carbon (Si@C) composite anode can be effectively prelithiated. The full cells composed of LiNi0.8 Mn0.1 Co0.1 O2 (NMC811) cathode and prelithiated Si@C anode exhibited increased capacities with the increment of prelithiation dosages.
