However, preparing SSPEs that can offer both mS cm–1-level ionic conductivity and high\({t}_{{\text{Li}}^{+}}\)(> 0.8) under ambient conditions remains arduous and is currently limited by (1) the strong Li–O−interactions between lithium salts and polymer backbones and (2) the...
State of health is a critical state which evaluates the degradation level of batteries. However, it cannot be measured directly but requires estimation. While accurate state of health estimation has progressed markedly, the time- and resource-consuming d
1. sodium hydroxide generates lithium oxide and water at the condition of 600 ℃ and in the absence of air, the chemical reaction equation: 2LiOH = Li2O + H2O 2. Under the heating conditions, the sodium hydroxide react with the magnesium or calcium can generate lithium and the corresponding...
The anode is a lithium containing compound and is generally one of three materials: a layered oxide (e.g. lithium cobalt oxide – LiCoO2), a polyanion (e.g. lithium iron phosphate – LiFePO4) or a spinel (e.g. lithium manganese oxide – LiMn2O4). ...
Moreover, the LT performance of metal sulfide/oxide anodes could also be significantly improved by expanding the lattice constant. An example refers to the synthesis of a MoS2/C composite with increased layer spacing through a soft-template method [63] (Fig.5a, b). Consequently, this modified...
Rechargeable lithium batteries using 5 V positive electrode materials can deliver considerably higher energy density as compared to state-of-the-art lithium-ion batteries. However, their development remains plagued by the lack of electrolytes with con
Perovskite-typed solid electrolyte (SE), with general formula of ABO3 (A = Ca, Sr, La, or Ba; BTi or Al), is a typical oxide SE with high ionic conductivity and chemical stability if Li is introduced to the A site. When anions occupy the position of cations and cations occupy anions...

After poling, we remove the electrodes with chromium etchant and buffered oxide etchant (Fig. 4b). Fig. 4: Device fabrication procedure. a We start with a 500 nm thin-film LN on an insulator. b For periodic poling of the LN film, we use chromium electrodes deposited on a 100 nm...
The key message is the need for a balanced AM/SE ratio and SE ductility to reduce the ionic ASR. However, even if we derive the ideal microstructure of SSBs at the particle level, it is also critical to rationally integrate these unit building blocks at the electrode level. Assuming that ...
