Lithium Batteries Could Last Longer And Behave Better
Mar 22, 2018

A new battery design invented by researchers at the Chinese Academy of Sciences and the University of Chinese Academy of Sciences could help overcome issues limiting the life and safety of lithium batteries. The findings by the Chinese researchers are fanning the expectations of demand for lithium in an already undersupplied market.

Lithium-ion batteries, while very reliable and popular for consumer electronics have their own imperfections related to safety and deterioration of battery capacity over time. The main culprit in both issues is dendrite formation. Dendrites, which build up over time inside the battery cells, can cause battery fires and were in fact one of the issues that were identified as the cause of Galaxy Note 7 spontaneous combustion in 2016.

 

A new battery design invented by researchers at the Chinese Academy of Sciences and the University of Chinese Academy of Sciences could help overcome this problem. The researchers have come up with a lithium-metal battery design, which is capable of suppressing dendrite formation, hence creating safer and longer lasting batteries. The new design also eliminates a common conundrum that afflicts conventional battery configurations. Existing methods to reduce dendrite growth often lead to resistance at the electrode/electrolyte interface and vice versa. This new method can deal with the two problems at the same time.
