At lower Lewis acid sites for HY zeolite, the glucose conversion is low, which is supported by the fact that Lewis acid sites is required for isomerization of glucose [54, 55]. In this study, all HY-ILs registered higher Lewis acid sites and higher LA yield compared to HY zeolite (high Bronsted acid sites) after immobilization of ionic liquid.

Diagram of the Li-ion battery discharge principle. Eq. (1) divides the heat generation of the battery into two parts, the first term is the irreversible heat (ohmic heat) and the other is S (entropy change) caused by the electrochemical reaction (Xu, 2022). The irreversible heat can be defined as Eq. (2): (2) where R is the resistance.
(1) T a has little effect on the low-current discharge of lithium-ion batteries, but has a greater effect on the high-current discharge of batteries. In particular, the higher T a during high-current discharge, the smaller the increase of HGR can be found when the battery increase the same current discharge.
