“…This results in a hundredfold improvement in the cell output, accompanied by a corresponding increase in the amount of silver transferred to the platinum electrode (6). We believe that some improvement in cell capacity could be achieved in a similar manner for thin-film cells by depositing electrodes of larger surface area or by introducing a graded layer of electrode-electrolyte mix between the electrode and electrolyte to increase their total overlap area.…”

“…In the presence of iodine vapor, the cell acts as a primary battery, the iodine being reduced at the inert Pt (or Ta) electrode. Mrgudich (6,7) has recently reported on the performance of AgI pellet batteries in which the AgI electrolyte is compressed between silver and platinum electrodes, and he also suggested that the possibility of making an all thin-film version of the system be explored. The Mrgudich batteries are rechargeable concentration cells in which the cell voltage is a function of the activity of Ag ~ on the inert platinum electrode and is given by the Nernst concentration-cell equation as E = (RT/nF) In-- [1] ap Here n is the valence change of silver to silver ions (i.e., unity), R is the gas constant, T is the absolute temperature, F is the Faraday constant, as is the activity of Ag ~ in the silver electrode which is constant and essentially unity, and ap is the activity of Ag ~ in the platinum electrode which is variable.…”

“…The electrolyte problem may be minimized by decreasing its thickness, while a reduction in double-layer boundary effects may be achieved by increasing the interface surface area. For example, the interface structure may be altered by mixing of the electrode and elec- trolyte materials thus making the mixture both an electronic and an ionic conductor (6).…”

Thin-film solid-state batteries ranging in thickness from 5 to 12~ were prepared on quartz substrates by vacuum-deposition techniques. Silver films ~1000A thick were used in all cases as the reversible electrode, while platinum and in some cases gold films of a similar thickness were used as the counterelectrode. Electrolyte films consisted of evaporated AgI, evaporated AgBr, and a double electrolyte of AgI evaporated onto a film of AgC1 or AgBr. Cells consisting of the above types of electrolytes were rechargeable, and the ones containing pure AgI or AgI -t-AgBr or AgC1 electrolyte exhibited long shelf life. Preliminary conductivity measurements using an a-c bridge method indicate, as expected, that the electrode-electrolyte interfaces rather than the electrolyte films are the principal sources of the high internal resistance exhibited by these batteries.The use of solid-state electrolytes in electrochemical cells was first demonstrated by Reinhold (1) during his studies of chemical equilibria between solid salts. Ionic conductivity in the solid state has since been studied by a number of workers and an extensive review of the subject has been presented by Lidiard (2). A more recent review by Raleigh (3) deals with the general aspects of solid-state electrochemical techniques and the use of solid-state galvanic cells for various thermodynamic calculations.Silver iodide, when contained between two metallic electrodes of which one is a reversible silver anode, has long been known to act as a solid electrolyte in which the ionic current is carried almost in its entirety by Ag + ions (4). In recent years, several articles have appeared in the literature on the utilization of silver iodide as an electrolyte in solid-state battery applications. A bead cell developed by Weininger (5) consists of a silver anode and a platinum or tantalum cathode embedded into the solid AgI electrolyte. In the presence of iodine vapor, the cell acts as a primary battery, the iodine being reduced at the inert Pt (or Ta) electrode. Mrgudich (6, 7) has recently reported on the performance of AgI pellet batteries in which the AgI electrolyte is compressed between silver and platinum electrodes, and he also suggested that the possibility of making an all thin-film version of the system be explored. The Mrgudich batteries are rechargeable concentration cells in which the cell voltage is a function of the activity of Ag ~ on the inert platinum electrode and is given by the Nernst concentration-cell equation

“…The concept of thin-film batteries or 𝜇-batteries have been proposed for a few decays. [1] However it is a long and difficult DOI: 10.1002/advs.202100774 match since the fabrication of the allsolid-state thin-film 𝜇-batteries (ATFBs) relies on the development of solid electrolytes with reasonably high ionic conductivity and chemical and electrochemical stability. That is why it was also called thin-film solid-electrolyte batteries in the early days.…”

Continuous advances in microelectronics and micro/nanoelectromechanical systems enable the use of microsized energy storage devices, namely solid-state thin-film -batteries. Different from the current button batteries, the -battery can directly be integrated on microchips forming a very compact "system on chip" since no liquid electrolyte is used in the -battery. The all-solid-state battery (ASSB) that uses solid-state electrolyte has become a research trend because of its high safety and increased capacity. The solid-state thin-film -battery belongs to the family of ASSB but in a small format. However, a lot of scientific and technical issues and challenges are to be resolved before its real application, including the ionic conductivity of the solid-state electrolyte, the electrical conductivity of the electrode, integration technologies, electrochemical-induced strain, etc. To achieve this goal, understanding the processing of thin films and fundamentals of ion transfer in the solid-state electrolytes and hence in the -batteries becomes utmost important. This review therefore focuses on solid-state ionics and provides inside of ion transportation in the solid state and effects of chemistry on electrochemical behaviors and proposes key technology for processing of the -battery.
