What Are Lithium Batteries, And How Do They Work?
Lithium batteries have become a vital part of our everyday lives, powering everything from smartphones to electric vehicles. But what exactly are lithium-ion batteries, and how do they work their magic? At the heart of a lithium-ion battery are two positive and negative electrodes, separated by a chemical compound called an electrolyte? The positive electrode, known as the cathode, is typically made of lithium cobalt oxide or lithium iron phosphate. The negative electrode, or anode, is commonly made of graphite. When the battery is charging, lithium-ions from the cathode move through the electrolyte to the anode, where they are stored as the battery charges.
History Of Lithium-Ion Battery Technology
Lithium-ion batteries have come a long way since their inception. The history of lithium-ion battery technology dates back to the 1970s when M developed the prototype. Stanley Whittingham. This early battery version utilized a titanium sulfide cathode and a lithium anode. However, it was in the 1980s that lithium-ion batteries gained commercial viability.
The breakthrough that revolutionized lithium-ion battery technology occurred in 1985 when John B. Goodenough introduced a new cathode material called lithium cobalt oxide. This material allowed for a significant increase in the energy density and voltage of the battery, making it more suitable for everyday applications.
Advantages Of Lithium-Ion Batteries Over Traditional Battery Types
Lithium-ion batteries have numerous advantages over traditional battery types, making them the go-to choice for powering our devices.
