The journey of battery technology has been marked by significant advancements, each bringing improvements in energy capacity, safety, and environmental impact. Here’s a look at how battery innovation has evolved from Nickel-Cadmium (Ni-Cd) to Lithium-ion (Li-ion), Solid-state Lithium, and now Sodium-ion (Na-ion) batteries.
Nickel-Cadmium (Ni-Cd) Batteries
Invented by Waldemar Jungner in 1899, Nickel-Cadmium batteries were among the first rechargeable batteries. They offered several advantages over lead-acid batteries, including better performance at low temperatures and a higher discharge rate. However, their use of toxic cadmium and relatively high self-discharge rates led to environmental concerns and a decline in their popularity.
