Your smartphone batteries emit over 100 toxic gases!

October 21, 2016

Washington, Oct 21: More than 100 potentially fatal gases are produced by the batteries found in billions of consumer devices such as smartphones and tablets, a new study has warned.

The research identified over 100 toxic gases released by lithium batteries, including carbon monoxide, which can cause strong irritations to the skin, eyes and nasal passages and harm the wider environment.

Researchers from the Institute of NBC Defence in the US and Tsinghua University in China said many people may be unaware of the dangers of overheating, damaging or using a disreputable charger for their rechargeable devices.

In the new study, they investigated a type of rechargeable battery, known as a "lithium-ion" battery, which is placed in two billion consumer devices every year.

"Nowadays, lithium-ion batteries are being actively promoted by many governments all over the world as a viable energy solution to power everything from electric vehicles to mobile devices," said Jie Sun, lead author and professor at the Institute of NBC Defence.
"The lithium-ion battery is used by millions of families, so it is imperative that the general public understand the risks behind this energy source," said Sun.

Sun and her colleagues identified several factors that can cause an increase in the concentration of the toxic gases emitted. A fully charged battery will release more toxic gases than a battery with 50 per cent charge, for example.

The chemicals contained in the batteries and their capacity to release charge also affected the concentrations and types of toxic gases released.

Identifying the gases produced and the reasons for their emission gives manufacturers a better understanding of how to reduce toxic emissions and protect the wider public, as lithium-ion batteries are used in a wide range of environments.

"Such dangerous substances, in particular carbon monoxide, have the potential to cause serious harm within a short period of time if they leak inside a small, sealed environment, such as the interior of a car or an airplane compartment," Sun said.

Almost 20,000 lithium-ion batteries were heated to the point of combustion in the study, causing most devices to explode and all to emit a range of toxic gases.

Batteries can be exposed to such temperature extremes in the real world, for example, if the battery overheats or is damaged in some way.

The researchers now plan to develop a detection technique to improve the safety of lithium-ion batteries so they can be used to power the electric vehicles of the future safely.

"We hope this research will allow the lithium-ion battery industry and electric vehicle sector to continue to expand and develop with a greater understanding of the potential hazards and ways to combat these issues," Sun concluded.

The study was published in the journal Nano Energy.

In an intriguing turn of events, authorities have levied a fine against an actress for breaching traffic regulations depicted within a television serial.

In the 14th episode of the popular serial ‘Seetha Raama’ a Kannada language drama series airing on Zee Kannada, a scene featuring two individuals riding a scooter caught the attention of viewers. While the rider adhered to safety protocols by wearing a helmet, the actress on the pillion did not.

Jayaprakash Yekkur, a vigilant resident of Mangaluru, took swift notice of this discrepancy and promptly lodged a complaint with the Mangaluru City Police Commissioner. Yekkur underscored the concern that such portrayals of traffic violations by actors and actresses could potentially convey misleading messages to viewers, particularly those who are impressionable. He urged authorities to take decisive legal action against the actress, the serial’s director, and the broadcasting channel.

In response to Yekkur’s complaint, the Commissioner of Police forwarded the matter to the Mangaluru Traffic Police station. Subsequently, notices were issued to the owner of the two-wheeler featured in the scene and the serial’s director. Upon investigation, it was revealed that the scene had been filmed in Nandini Layout, Bengaluru, and was referred to the Rajajinagar police station for further scrutiny.

On May 10, after thorough inquiries, the Rajajinagar police station imposed a fine of Rs 500 on both the actress and the owner of the two-wheeler. Furthermore, the production manager of the serial committed to adhering strictly to traffic regulations in future episodes.

Expressing his contentment with the resolution, Jayaprakash Yekkur commented that the prompt response from the police, coupled with the imposition of a fine, serves as a valuable lesson and contributes significantly to enhancing public awareness.

Mangaluru: Disgruntled BJP leader and former MLA K Raghupathi Bhat, who is contesting the legislative council election as an independent candidate from the South West Graduates constituency, said the BJP has adopted the “godfather culture” of the Congress.

Bhat told reporters here on Saturday, that he has not tried to appease any senior BJP leaders to get a party ticket to contest the MLC poll.

“I am contesting and seeking votes based on my achievements. My contesting may have a negative impact on the BJP. However, I want to go back to the BJP after winning this election,” Bhat said, and refused to answer the actual reason for the denial of a BJP ticket to him.

“I have no idea who played from behind that I was denied a ticket for the MLC poll.

Earlier, the BJP had a culture of selecting candidates for MLA and MLC polls by seeking the opinion of party workers at the booth level, followed by discussions at mandal and district levels.

Now the situation is such that even if one person’s name was sent from the state, the final list will be different. The godfather culture of the Congress has stretched into our party too. Only those who appease leaders get a ticket in the BJP. However, I have not appeased any leader. I believe in the support of party workers, and with this confidence I am contesting the election,” Bhat said.

To a query, Bhat said that he has not contacted by BJP leaders after deciding to contest the MLC poll.

“I have already requested all leaders that I should get the party’s Form B to contest the MLC poll from the South West Graduates constituency. I have told them that I am also contesting as an independent candidate on behalf of the BJP. The ultimate aim of my contesting the election is that senior leaders should know the injustice that honest party workers are facing in the BJP,” he said.

Madikeri, May 11: Kodagu police have apprehended the man allegedly responsible for the brutal murder of a minor girl within the confines of Kumbaragadige village in Karnataka's Somwarpet taluk. 

Kodagu Superintendent of Police, K Ramarajan, disclosed that the arrested individual is Prakash (32) from Hammiyala village in Somwarpet taluk. However, authorities are still in the process of recovering the severed head of the victim. The perpetrator had absconded with the victim's severed head after committing the crime. 

Search operations for the suspect commenced late on Thursday night (May 9), with officials diligently pursuing leads. Acting on information suggesting the suspect's presence in a forested area near the village, the police swiftly moved in and apprehended him.

The victim US Meena, 15, a student of Surlabbi High School, had passed the SSLC examinations, the results of which were announced on May. One same day, she was murdered. 

Reportedly, the engagement of the minor girl with the suspect was thwarted by officials from the Women and Child Development department. Subsequently, officials persuaded the girl's parents against proceeding with the marriage. 

However, despite these interventions, the suspect forcibly entered her residence during the night, purportedly abducted her, and later perpetrated the heinous crime in a wooded area on the outskirts of the forest, before absconding with her severed head.
