As part of our work in this field, we want to share information on the foundations and current landscape of electrochemical safety. Visit the Initiative Updates tab to dive deeper into these concepts and download resources.
What Are Lithium-Ion Batteries?
Lithium-ion is the most popular rechargeable battery chemistry used today. Lithium-ion batteries consist of single or multiple lithium-ion cells and a protective circuit board. They are called batteries once the cell or cells are installed inside a device with the protective circuit board.
Where Are Lithium-Ion Batteries?
Products powered by lithium-ion batteries — from wearable technology and mobile phones to satellites and electric buses — require a range of specifications for optimum and safe performance with respect to energy, power and life span. Learn about the variety of formats they are produced in.
What is Thermal Runaway?
One of the primary risks related to lithium-ion batteries is thermal runaway. Thermal runaway is a phenomenon in which the lithium-ion cell enters an uncontrollable, self-heating state. Thermal runaway can result in extremely high temperatures, violent cell venting, smoke and fire.
What Causes Thermal Runaway?
Faults in a lithium-ion cell, which can be caused by internal failure or external conditions, can result in thermal runaway. One example of internal failure is an internal short circuit caused by defects in the cell that compromise the separator’s integrity.
