Dry-cell battery

In 1886, German scientist, Dr. Carl Gassner, was issued a German patent (No. 37,758) for the first "dry" cell, which used zinc as its primary ingredient. He encased the cell chemicals in a sealed zinc container. Gassner's battery was much like the carbon-zinc, general-purpose batteries on the market today. Gassner also patented his invention in Austria, Belgium, England, France and Hungary in the same year. A U.S. Patent was issued to Gassner in 1887 (No. 373,064) on November 15, 1887. In 1896, the first mass produced batteries were sold by the National Carbon Company which made portable electric devices practical.
