Batteries By- ryan thorpe

The first batteries that were made were nothing like todays batteries. The guy that made the battery was Alessandro Volta. He found that by stacking copper and zinc with a paper with a salt water soulution between the two it made the battery.We use batteries in our every day life. without batteries life would be way different. When a device is connected to a battery a light bulb or an electric circuit. Chemical reactions occur on the electrodes that create a flow of electrical energy to the device.

Batteries are one of the biggest limitations in the advancement of wearable technology. While they continue to improve slowly, they’re still a significant constraint as we try to make them last longer or make them smaller.
