Lithium-ion battery safety courses

Lithium-ion batteries have high energy density, so they can store more energy in a compact size, making them ideal for portable electronics and electric vehicles. Lithium-ion batteries have relatively low self-discharge rates and can deliver high power output, providing efficient and reliable energy storage. 

They also have a long cycle life, meaning they can be recharged many times before their performance significantly degrades.  

Lithium-ion batteries are generally safe when used and handled correctly, thanks to built-in safety features like thermal controls and protective circuits.  

Their biggest problem is the risk of overheating and catching fire, known as thermal runaway, which can occur if the battery is damaged, overcharged, or exposed to high temperatures. 

Lithium-ion batteries typically last between 2 to 5 years or 300 to 1,000 charge cycles, depending on the specific battery type, usage patterns, and environmental factors.  

High-quality batteries used in premium electronics and electric vehicles may last longer due to advanced cell technology and better thermal management systems.  

Lithium Iron Phosphate (LiFePO4) batteries, which are used in electric cars, are considered the safest types of lithium-ion batteries due to their stable chemical structure, which makes them less prone to overheating, thermal runaway, or catching fire compared to other lithium-ion chemistries. They also have a longer cycle life and can tolerate higher temperatures.  

All lithium-ion batteries are designed to be rechargeable. However, like all rechargeable batteries, their capacity to hold a charge diminishes over time with repeated charging and discharging cycles.  

Proper care, such as avoiding overcharging and deep discharging, can help extend their lifespan. 

Lithium for lithium-ion batteries is primarily extracted from mineral ores and brine deposits. Major sources include lithium-rich minerals like spodumene, found in hard rock deposits, and brine deposits located in salt flats or saltwater lakes, such as those in the “Lithium Triangle” of Argentina, Bolivia, and Chile.  

Lithium can also be extracted from certain clay deposits and is increasingly being recovered through recycling of used batteries to meet growing demand.
