Rechargeable batteries or secondary cells are found in everyday devices like digital cameras, laptops, tablets, cell phones and electric cars like Tesla S. Although rechargeable batteries are found in most of society’s modern devices, rechargeable batteries can be traced back to 1859 when the lead acid cell was invented by French Physicist Gaston Plante. Early Secondary cells batteries were “ awkward bulky and oversized with antennas…”( “rechargeable batteries, a history 1”). There are different types of rechargeable batteries but Nickel Cadmium or NiCad was the first one to be introduced onto the market in 1899. “Nickel-Cadmium batteries consists of an anode composed of solid cadmium and a cathode composed of NiO(OH)” ( Tro 839). Nickel-cadmium rechargeable works by oxidizing solid cadmium and reducing nickel oxide to produce an Energy cell of 1.30 voltage. Nickel-Cadmium batteries were perfect for portable tools like mobile phone and other devices due to it’s small size, high life expectancy and ability to discharge capacity at a high rate. This rechargeable battery advantages are immense but it also comes with disadvantages that can cause serious harm to the environment. Lenient environmental policies in the 19th century meant environmental concerns regarding the use of this rechargeable battery did not exist. “Cadmium is a highly toxic heavy metal and can cause substantial pollution when landfilled or incinerated”(“Disadvantages of Ni-Cd…
