“…The derivation below of the SSLIB model is based on the experimental charge-discharge regularities obtained for cells of different electrochemical systems. The test cells were manufactured by high-frequency magnetron sputtering [7] at the SCR-651 "Tetra" (Alcatel, France) system using mask technology. Technological parameters of functional layer deposition are given in Table 1.…”

“…Research on silicon application as a negative electrode is not widely adopted, due to its instability as the anode material. Obtaining a stable electrode material based on silicon is possible only in the form of the Si@O@Al nanocomposite, which nevertheless has a high specific capacity-from 1.000 to 3.000 µA • h/g (depending on the ratio of elements) [7].…”

The results from measuring the capacity of thin-film solid-state lithium-ion batteries (SSLIBs) Ti|Si@O@Al|LiPON|LiCoO2|Ti, Ti|Si@O@Al|LiPON|LixV2O5|Ti, and Ti|LiPON|LiCoO2|Ti at different charge currents are reported. It is shown that the dependence of the capacity on the current density Q(j) follows Peukert’s law, which is characterized by a low value of Peukert’s exponents in the region of low currents and a high value of the exponents in the region of high currents. Peukert’s exponent for the anode-free cell remains constant through the entire range of current density variation. A model for SSLIB capacity based on the balance of ion (diffusion and drift) and electron currents is proposed. The model predicts a Q(j) dependence well approximating the experimental results and fitting Peukert’s law. The model allows a qualitative interpretation of the change in the Peukert exponent with increasing current density, based on the effect of the charge current saturation.

The results of measuring the capacity of a thin-film solid-state lithium-ion battery (SSLIB) Ti|Si@O@Al|LiPON|LiCoO2|Ti at different charge currents are reported. It is shown that the dependence of the capacity on the current density follows the Peukert's law, which is characterized by a low value of the Peukert’s exponent in the region of low currents and a high value of the exponent in the region of high currents. A capacity model for a SSLIB based on the balance of diffusion and migration currents is proposed and the dependence of the capacity on the charge current is derived. The obtained dependence is well approximated by Peukert's law with an exponent of 1.39, which is intermediate between the exponents for lithium-ion batteries with liquid electrolyte and SSLIBs.
