    Abstract: An electrochemical device, including an electrode and an electrolyte. The electrolyte including a dinitrile compound, a trinitrile compound, and propyl propionate. Based on the total weight of the electrolyte, the weight percentage of the dinitrile compound is X, the weight percentage of the trinitrile compound is Y, and the weight percentage of the propyl propionate is Z. Wherein about 2 wt %≤(X+Y)≤about 11 wt %, about 0.1≤(X/Y)≤about 8. The electrode including a coating, which including a single-sided sub-coating and a double-sided coating, the electrode with the single-sided sub-coating has an electrode compaction density D1, and the electrode with the double-sided coating has an electrode compaction density D2, where about 0.8≤D1/D2≤about 1.2. The electrolyte and D1/D2 of the electrodes has a significant effect on the cycle performance of the electrochemical device.

    Abstract: A drawable adhesive tape and a drawable adhesive tape product. The drawable adhesive tape includes: a base framework extending along length direction of the drawable adhesive tape and having a plurality of adhesive-accommodating regions which extend along both thickness direction of the drawable adhesive tape toward interior of the base framework and length direction of the drawable adhesive tape and which are arranged at intervals along width direction of the drawable adhesive tape, and an adhesive layer filled in the adhesive-accommodating regions. The drawable adhesive tape product includes a release paper and the drawable adhesive tape, in which, a surface of the drawable adhesive tape where the adhesive-accommodating regions are located is covered by an oily surface of the release paper. The drawable adhesive tape and drawable adhesive tape product have improved tensile strength and improved adhesion strength.
