A mother liquor was prepared. This reaction mother liquor has a length/I cyr and a width of 0.3 ttr.
R low pressure etching aluminum chemical formation 3) (capacity is approximately 10 μF/10 cm2 when using an electrolyte of ethylene glycol and ammonium adipate) and heated at 85°0.
The reaction was carried out for 40 minutes. The produced carbon dioxide (k)V4 was thoroughly washed with water and dried at 120°C for 2 hours at reduced speed. Next C
Four cans of silver paste were poured onto the conductive layer of lead 1 dioxide and allowed to solidify at room temperature. Thereafter, the cathode terminal was taken out using a hanger and sealed with resin to produce a solid electrolyte.
