“…Sn has attracted the attention of many scientists for its high theoretical capacity (994 mA h g –1 for Li 4.4 Sn). However, the massive volume changes during charging/discharging (∼360%) will lead to the separation of the tin anode and current collector, and the ultimate failure of the battery. − In addition, the volumetric deformation of the tin anode causes intense structural crushing and the successively continuous formation of solid electrolyte interphase (SEI) layers. This results in the irreversible lithium consumption and rapid capacity decay .…”

Herein, we present the facial preparation of one-dimensional nanoscale square rod array Sn−Co−Cu alloy films through electrodeposition and subsequent annealing methods under the template-free condition, and their electrochemical performances of the assembled lithium cells as anode were tested in detail. The results indicated that the anodes displayed an excellent cyclic performance. The discharge capacities of the anodes were 1072 and 897 mA h g −1 at the corresponding current densities of 200 and 2000 mA g −1 after 500 cycles, with a high capacity retention of ∼92.3%. Moreover, the excellent capacity reversibility was confirmed when cycled at multiple C-rates of 0.2, 0.5, 1.0, 2.0, and 5.0 and then 0.2, and 5.0 A g −1 . This attractive electrochemical characteristic is likely due to the anode with morphology of the nanoscale square rod array. Such structure can accommodate the volume expansion of Sn−Co−Cu alloy film anodes and offer large surfaces and more active sites. The kinetic process of Li + lithiation and delithiation was also characterized based on cyclic voltammetry experiments in a lithium cell whose anode was the Sn−Co−Cu nanoscale square rod array film. The results showed that the kinetics process was mainly dominated by semi-infinite linear diffusion and surface reaction and that the contribution of pseudocapacitance increased with the increase of scan rate.

“…With the rapid development of lithium-ion batteries (LIBs) in the past decade, tin has also been explored as a possible active material in the electrochemical energy storage field. 5–8 For example, Sn and its alloys, such as Sn–Cu, 9 Sn–Ni, 10 Sn–Co 11 and Sn–Fe 12 can be used as the anode for LIBs because they can alloy/dealloy with lithium, exhibiting a high capacity with a suitable working voltage range. A few researchers have also demonstrated molten metal–metal batteries using tin–antimony–bismuth as the cathode, but these cells only have a discharge voltage of less than 0.8 V and also have to be operated at a temperature typically above 500 °C, in which tin is mainly used to decrease the melting point of the cathode alloy.…”

“…Due to fossil fuel depletion and pollution, new energy research focuses on cost-effective and environmentally friendly technology. Lithium-ion batteries have a low self-discharge rate, a longer lifespan, a higher energy density, and a lower price, making them excellent for energy storage in portable electronic devices. − Safety performance is vital toward this endeavor and has become a technological barrier for industrial production on a broad scale. LIB electrolytes contribute to safety problems with batteries.…”

Exploring the Effects of Dopamine and DMMP Additives on Improving the Cycle Boosting and Nonflammability of Electrolytes in Full-Cell Lithium-Ion Batteries (18650)

Concerns over recyclability, performance, and safety have grown as the use of commercial Li-ion batteries to meet our energy needs has increased. Electrolytes may aid in increased flammability, capacity loss, and safety. Dimethyl methyl phosphonate (DMMP), a flame retardant, and dopamine hydrochloride (DOP) are utilized to increase the cycle life and graphite anode compatibility. The optimal additive formulation (5% wt DMMP and 0.1% wt DOP) reduces inflammability and increases cycle life and reversible capacity (99.14%). Molecular dynamics simulations provide a comprehensive atomistic account of the dynamics of Li + ion solvation in the electrolytes and in the presence of additives. Dopamine and DMMP increase the Li-ion solvation-free energy in the electrolyte formulation. While increasing the Li-ion conductivity, additive addition reduces the electrolyte viscosity and enables the formation of a smaller, stronger Li-DMMP-DOP complex than the larger Li-carbonate complex found in Li-neat electrolyte systems. When DMMP and DOP are added to the electrolyte, the carbonates are displaced from the Li-carbonate complex by these additives. The Li-ion solvating nature or compatibility was improved upon the addition of DMMP/DOP further aided by a faster diffusive behavior of the Li complex, which in part would be instrumental in enhancing the performance and safety of the battery electrolyte additive formulations. The modified electrolyte (DMMP 5% wt, DOP 0.1% wt) has a conductivity of 18.60 mS cm −1 and a low viscosity at 25 °C. This formulation was evaluated using graphite/NMC-532 cylindrical cells with commercial electrodes. The performance of the graphite/NMC-532 cells containing the modified electrolyte was comparable to those of regular electrolytes based on carbonates: ethylene carbonate/ dimethyl carbonate/ethylmethylcarbonate (EC/DMC/EMC) (1:1:1) additions. These findings indicate that DOP and DMMP have a lower oxidation potential (4.3 V) than most commercial electrolytes (4.5 V), preventing cathode deterioration. These insights should pave the path for rational design of practical and cost-effective Li-ion battery electrolyte additive combinations aimed toward lower flammability and improved performance.
