The entire internal working of lithium-ion (Li-ion) batteries that leads to their overheating and exploding, has finally been revealed by scientists, according to a report published by Nature communications.

According to scientists, understanding how Li-ion batteries fail and potentially cause a chain reaction is important for improving their design and make them safer to use and transport.

Speaking on the experiment to study the Lithium batteries, Donal Finegan from University College London (UCL) said, “We combined high energy synchrotron X-rays and thermal imaging to map changes to the internal structure and external temperature of two types of Li-ion batteries as we exposed them to extreme levels of heat.”

The scientists exposed the battery shells to temperatures in excess of 250 degrees Celsius, and then looked at the effects of gas pockets formation, venting and increasing temperatures on the layers inside two distinct commercial Li-ion batteries

The battery with an internal support remained largely intact up until the initiation of thermal runaway, at which point the copper material inside the cell melted indicating temperatures up to 1,000 degrees Celsius.

This heat spread from the inside to the outside of the battery causing thermal runaway.

In contrast, the battery without an internal support exploded causing the entire cap of the battery to detach and its contents to eject.

Prior to thermal runaway, the tightly packed core collapsed, increasing the risk of severe internal short circuits and damage to neighbouring objects.

“Hopefully from using our method, the design of safety features of batteries can be evaluated and improved,” said corresponding author Paul Shearing, also from UCL.

The UK government on Thursday announced that it will move India from the red to the amber list on Sunday, in the country's latest update to the 'Red-Amber-Green' traffic light ratings for arrivals into England amid the Covid-19 pandemic.

This means the visit visas for the UK from India are open, in addition to other long-term visas that have remained open. But travellers from India arriving in England can complete a 10-day quarantine at home or in the place they are staying (not mandatorily quarantine in a managed hotel).

Pakistan has failed miserably to protect Hindus, their interests.

A Hindu temple in Pakistan's Punjab province was reportedly vandalized by hundreds of people after a nine-year-old Hindu boy, who allegedly urinated at a local seminary, received bail, a media report said on Thursday.

According to the Dawn news report, the incident took place on Wednesday in Bhong town, about 60 km from Rahim Yar Khan city.

Besides the vandalization, the mob also blocked the Sukkur-Multan Motorway (M-5), the report added.

Citing sources, Dawn news said that a case was registered against the minor on July 24 based on a complaint filed by a cleric, Hafiz Muhammad Ibrahim, of the Darul Uloom Arabia Taleemul Quran.

The sources said that "some Hindu elders did tender an apology to the seminary administration saying the accused was a minor and mentally challenged".

But, when a lower court granted him bail a few days ago, some people incited the public in the town on Wednesday and got all shops there closed in protest, the report quoted the sources as further saying.

A video clip showing people wielding clubs and rods storming the temple and smashing its glass doors, windows, lights, and damaging the ceiling fans went viral on social media.
