Historical Progression for Development of Lithium-Ion Batteries:
The development of lithium-ion batteries began in the 1970s when scientists started investigating lithium as a possible material for the anode due to its low weight and strong electrochemical potential. Nonetheless, it was not until the 1990s that Sony introduced the first commercially available rechargeable lithium-ion batteries, therefore transforming the landscape of portable electronics. Subsequently, a deliberate combination of scientific investigation, technological advancements, and engineering achievements has catapulted lithium-ion batteries from their early stages to their current importance.
Constituents for the Development of Lithium Ion Batteries:
Development of Lithium-ion batteries consist of four essential components, each of which plays a crucial part in their operation:
- Typically composed of graphite, the anode serves as the storage location for lithium ions during battery charging.
- The cathode, which consists of different materials like lithium cobalt oxide, lithium iron phosphate, or lithium manganese oxide, enables the insertion and removal of lithium ions throughout the process of charging and discharging.
- A separator is a permeable membrane that prohibits direct contact between the anode and cathode, preventing short circuits while allowing the movement of lithium ions.
- Lithium salts dissolved in a solvent form an electrolyte, a solution that conducts electricity. It allows for the movement of lithium ions between the anode and cathode during battery charging and discharging
Stages of Development of Lithium Ion Batteries:
We can divide the progression of development of lithium-ion batteries into clearly defined stages of development:
