These ions move through a liquid electrolyte which is highly flammable \u2013 and that is why when one overcharges a lithium-ion battery, it overheats and can even explode.<\/p>\n<p>To demonstrate, Dr Balaya overcharged a single battery cell, applying more than 5 volts instead of the recommended 4.3 volts. The cell was observed slowly bulging, and then it began to emit smoke before abruptly exploding in a spectacular orange burst.<\/p>\n<p>\u201cIf this explosion happened at the pack level, it would be a very massive one,\u201d he pointed out.<\/p>\n<p>Palani Balaya of the National University of Singapore, Centre for Energy Research &amp; Technology (CERT), was featured in Talking point to demonstrate how ans why Lithium Ion batteries explodes.<\/p>\n<\/div>\n<div class=\"pw-hidden-cp\">Credits:\u00a0 https:\/\/www.channelnewsasia.com\/news\/singapore\/lithium-ion-battery-charger-explode-fire-phone-scooter-9934958<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>1.\u201cWhy Batteries Explodes\u201d When a lithium-ion battery is being charged, the ions move from the positive to the negative electrode at a fairly high voltage of 3.7 volts \u2013 much higher than the 1.5 volts in a typical alkaline battery.
