“…This result suggests that the initial LTO electrode-electrolyte passivation products formed during the first three cycles are not stable; however, with additional cycling a more optimal SEI forms. Yan et al [129] in their study of the EEH electrolyte found that the SEI formed on graphite contained more organic compounds than a EEF electrolyte (1 M LiPF6 proposed mechanism was provided [135]. Table 4-8 shows an approximate 20% decrease in Rct for E1 cells indicating the ionic conductivity of the SEI improves.…”

A MULTI-FUNCTIONAL ELECTROLYTE FOR LITHIUM-ION BATTERIESThermal management of lithium-ion batteries (LIBs) is paramount for multi-cell packs, such as those found in electric vehicles, to ensure safe and sustainable operation. Thermal management systems (TMSs) maintain cell temperatures well below those associated with capacity fade and thermal runaway to ensure safe operation and prolong the useful life of the pack.Current TMSs employ single-phase liquid cooling to the exterior surfaces of every cell, decreasing the volumetric and gravimetric energy density of the pack. In the present study, a novel, internal TMS that utilizes a multi-functional electrolyte (MFE) is investigated, which contains a volatile co-solvent that boils upon heat absorption in small channels in the positive electrode of the cell.

“…Thin film electrodes have been widely investigated, and very significant improvements have been made to decrease their manufacturing time, preparation temperature and cost, and to increase their capacity and improve their cycling behavior [14]. Thin film anode materials have also been recently reported [15,16]. Alloy electrodeposition is widely used in the production of new materials with specific mechanical, chemical and physical properties [17,18].…”

“…One way to circumvent and reduce such volume expansion is to form intermetallic compounds where one metal is inactive with respect to lithium alloying while the other metal is active. Cu 2 Sb is one example 11,12 of such a negative electrode material. The Sb electrodeposition strategy adopted in this case included careful control of the local pH at the electrode to prevent formation of Sb 2 O 3 .…”

“…3) has been to directly use the copper nanorod current collector made on a planar copper surface as a platform for the synthesis of the negative electrode material. 10,11 A suitable material in this respect is antimony (Sb), as it is known to alloy with lithium; this process however would result in a large volume expansion, which limits cycling and battery lifetime. One way to circumvent and reduce such volume expansion is to form intermetallic compounds where one metal is inactive with respect to lithium alloying while the other metal is active.…”

“…The Sb electrodeposition strategy adopted in this case included careful control of the local pH at the electrode to prevent formation of Sb 2 O 3 . 10,11 After deposition, the sample was heat-treated for 12 hours at 300°C to ensure the formation of Cu 2 Sb-nanorods with a core of Cu. The sample was found to exhibit excellent capacity retention with a capacity about ten times higher than for a 2D sample treated in the same way.…”

I t is not difficult to explain the increasing worldwide interest in battery development. The current changes in the global energy outlook, including the shift to a higher fraction of solar and wind power, as well as the declining use of fossil fuels in vehicles, call for new autonomous energy storage solutions. The downscaling of microelectronic systems to produce small devices such as medical implants, micro sensors, self powered integrated circuits or microelectromechanical systems (MEMS), requires rechargeable batteries with better energy and power densities per footprint area than can be achieved with the thin film 2D batteries existing today.Today's rechargeable lithium-ion batteries-with the best performance when it comes to energy density and with a reasonably good power efficiency-are dominating the market for consumer electronics. There is, however, a need for rechargeable storage devices that combine small volume with high energy and power densities. Typically, there is a demand for batteries on the 1-10 mm 3 volume scale, including all components and associated packaging. Moreover, miniaturized devices usually need the energy storage functions to be physically located on a small area-on a chip-making the energy and power density per footprint area a key factor for these batteries. The energy demand for these products is generally in the order of 1 J/(mm 2 day), which conventional battery technologies fail to supply by an order of magnitude or more. Given the wide range of electrode chemistries available for lithium-ion batteries, these batteries are well-suited to be shaped into different complex 3D high-capacity architectures.This article focuses on the use of electrodeposition as a tool for manufacturing complex 3D battery architectures.
