History of Battery
Society's need of energy has resulted technological development. This world is in need of power supply more than ever. Despite the advances from power, batteries allowed storage and decrease of energy that created many suitability’s that it’s now taken for granted. The history and advances of battery dates back in time, and the recent advances are making them unnoticeable; batteries are safer, long lasting and recyclable now.
Early History
It has been suggested that batteries were invented over 2,000 years ago. The invention discovered in Baghdad in 1932, might have just been used for jewelry making. Real progress of storing electric current was made again in the late 18thcentury, when Alessandro Volta (after whom volt was named) shelved discs soaked in salt solution between zinc and copper plates to create electric current. This formed the base for the battery technology.
Present
The first wet cell batteries (like automobile) and dry cell batteries (like the remote control ones) was invented in the late 19th century. By 1900 the D battery was powered in flashlights. The rechargeable battery is about 150 years old, and today’s' cars batteries use the original lead-acid design. Batteries have been focused on light weight and longer lasting batteries like for iPods and etc. The rechargeable battery has gone through three major changes:
Nickel-Cadmium (NiCd): First used in the 1960s, for dry cell rechargeable batteries. But, cadmium is toxic and these batteries are disposed to memory effect. Like, if it is repeatedly charged when it is at 50 percent power, it will forget that it has the other 50 percent, and
