Strategies For Improving the Safety of Lithium-Ion Batteries

Lithium-ion batteries are extensively used in a range of devices due to their benefits, which include high energy density, enormous output power, and high average output voltage. There are several incidents every year brought on by lithium-ion battery failures, yet few people take the initiative to be aware of the possible safety risks associated with lithium-ion batteries. Identification and mitigation of lithium battery safety hazards are therefore essential. The article first analyzed the phenomenon of thermal runaway, and discusses various monitoring systems. Then, the application of fiber Bragg grating sensors in real. time detection of battery data was emphasized. Finally, a summary of the methods employed to lessen the safety issues connected with lithium batteries was provided. These methods included the use of electrode surface coatings, electrolytes, separators, and suppressing lithium dendrites. This will have reference value for future research on the safety of lithium batteries.
