Researchers Make Lithium-Ion Batteries Safer

Researchers from Taiwan's Industrial Technology Research Institute have developed a new material that will make lithium-ion batteries safer to use in today's electronic devices. Li-ion batters are used in mobile phones, and there have been some instances where batteries overheated and caused fires and/or injuries. The cause of these fires is batteries that short circuit, most often due to damage. To prevent li-ion batteries from short circuiting, the researchers created a new polymer, called STOBA (self-terminated oligomers with hyper-branched architecture). This polymer is applied to the cathode material inside a li-on battery, which prevents the battery from short circuiting if it is damaged. The researchers say the material will add only 2% or 3% to the cost to manufacture the battery. The researchers say the material is ready for use, though no battery makers have publicly committed to using it.
