Coin-shaped lithium secondary battery and IoT device
摘要
說(shuō)明書
The positive electrode current collector, the carbon layer, the LCO positive electrode plate, a cellulose separator, the LTO negative electrode plate, the carbon layer, and the negative electrode current collector were accommodated between the positive electrode can and the negative electrode can, which would form a battery case, so as to be stacked in this order from the positive electrode can toward the negative electrode can, and an electrolytic solution was filled therein. Thereafter, the positive electrode can and the negative electrode can were crimped via a gasket to be sealed. Thus, the coin cell-shaped lithium secondary battery 10 with a diameter of 12 mm and a thickness of 1.0 mm was produced. At this time, the electrolytic solution was a solution of LiBF4 (1.5 mol/L) in a mixed organic solvent of ethylene carbonate (EC) and γ-butyrolactone (GBL) at 1:3.
(4) Evaluation
The LCO sintered plate (positive electrode plate) prepared in Procedure (1 b), the LTO sintered plate (negative electrode plate) prepared in Procedure (2b), and the coin-shaped lithium secondary battery manufactured in Procedure (3) were evaluated for various properties as shown below.
