The Need
• People needed a source of electricity to power portable devises.
• The energy source had to be durable, long-lasting, and small.

History
• Devises called Leyden jars which consisted of silver foil that held a charge
• Multiple Leyden jars were put together to hold a greater charge.
• Benjamin Franklin first coined the term “battery” for multiple Leyden jars put together.

Alternate Solutions
• There were no alternative solutions because the only devise that was used at the time to store energy was the Leyden jar.

Innovations
• The Galvanic cell was an early form of current batteries. – It used combinations of
chemicals and metals connected by a bridge of porous material.
• Multiple Galvanic cells were stacked together to form what is known as a voltaic pile. – These devises were unreliable
so they could not be used for portable devises.

Innovations (Cont…)
• The Daniel cell, which was made in 1836, was the first wet cell battery, which is a battery that uses liquids in glass containers. – These devises were very fragile but produced a
consistent charge.
• By the end of 19th century, dry cell batteries were made using a paste instead of liquid.– These devises were very durable and they still
produced a consistent charge.

Results of Invention
• The battery allowed for the use of all the portable electronic devises that existed then and exist now.

Quality Control
• Batteries have to adhere to the standards put in place by the International Organization of Standardization (ISO), the American National Standards Institute (ANSI), and other standards organizations.

Today’s Batteries
• Batteries only got smaller, more efficient, and cheaper from the 19th century.
• There are now many types of batteries utilizing many types of chemicals.

Disposal
• Thrown out as solid waste or material is salvaged in battery recycling.
