All OS Youth Severely Injured as Mobile Phone Explodes

[blr_p]

This happened a month back but did not see any posts about it. The IE the day after had an article that offered more explanation as to what actually happened.

A Bindiganavile police sub-inspector, however, denied reports of the blast being caused by a mobile phone.

He said it was the mobile charger used by Sitaram that had a loose connection.

When Sitaram tried to tighten the wire with his teeth, electricity passed through and there was a blast, he said.

“As no earthing was done for electric supply, he was severely injured. All the news of a mobile blast is just false,” he added.

it seems like he put a live wire into his mouth and got electrocuted.

not really. There have been cases like this from time to time. it creates all sorts of theories.

- never talk on the phone when it is charging.
- don't buy rebrands because the quality checks are not good.
- Fake battery.
- Charging circuit failed.

The day earlier Feb 5 the papers mentioned it was a lava phone that 'blew up'.

One i posted showed that none of the above applies and clarified.

yes, had read about the incident in the news. there were speculations earlier including the above, and that perhaps the charger was at fault, and i recall reading about the victim using his teeth to tighten the wire or something of that sort. good to see a follow-up on it. poor chap! felt sorry for him. hope he recovers from the ghastly injury.

Here is another from three months ago.

Cellphone cloud on youth's death

Don't know what caused it but this time the guy died, injuries seem consistent with electrocution.

Electrochemical scientists who specialise in battery technology said traditional lithium batteries are at risk of exploding under certain rare circumstances when they experience higher than rated voltage or temperature.

The charging voltage for a mobile phone battery should remain below 4.2 volts and the temperature should remain below 120°C, said Padikkasu Periasamy, a senior scientist at the Central Electrochemical Research Institute, Karaikudi, Tamil Nadu. "If either exceeds the values, there is a risk of explosion," he said.

How charging voltage exceeded 4.2 volts ins't clear.

something more from snopes...

Worldwide, a number of cells exploded in 2003, a great many of them Nokia phones. According to Nokia, third-party or counterfeit batteries were to blame: in each and every exploding phone case it investigated, the battery in question proved not to be original to the unit and not to have included industry-standard safety measures. It also found the vast majority of short circuits that led to these explosions were caused by the units' having undergone traumatic events (such as being dropped) which jeopardized the integrity of poorly-manufactured batteries.

All day-to-day use lithium-ion batteries are likely to get into thermal runaway situation which in turn can cause explosion of the battery. This is also the cause of battery failure and explosion issues with Boeing's Dreamliner series of aircrafts. No matter who produces the battery, there is a small likelihood of this thing happening. A well manufactured battery is rare to explode in such a fashion but nevertheless there is a probability - however small it may be. Since such situations are rare, the risk is at par or better in relation to every other day to day use items.
