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.

Mysuru, Apr 29: Veteran politician and incumbent Chamarajanagar MP V Srinivas Prasad breathed his last at 76.The stalwart BJP leader, who had been battling health issues, succumbed to a severe heart attack, leaving behind a void in Karnataka's political arena.

A Dalit leader in the Old Mysuru region, Prasad was in Congress but joined the Bharatiya Janata Party before the 2018 Karnataka Assembly elections following a fallout with Chief Minister Siddaramaiah. The two had recently met in Mysuru and discussed the political scenario in the state.

Prasad extended support to the Congress in the Lok Sabha election 2024 and this is being seen as a crucial factor in the SC-reserved Chamarajanagar constituency, which Prasad represented in Parliament. On April 2, Prasad’s relatives and supporters joined Congress.

He served as a Union minister from 1999 to 2004 as the Loka Jana Shakthi MP. In the Karnataka Assembly elections, he was elected twice as an MLA and served as the state’s revenue minister.

Prasad, known for his distinguished political career spanning over five decades, was admitted to Manipal Hospital in Bengaluru due to urinary tract-related complications and age-related ailments.

However, his condition deteriorated rapidly, leading to his untimely demise in the wee hours of Monday.

Born on August 6, 1947, in Ashokapuram, Mysuru, Prasad's political journey was marked by significant milestones. He represented Chamarajanagar constituency as MP for an unprecedented seven terms and had derved as MLA from Nanjangud constituency twice.

He had held key ministerial portfolios including Minister for Food and Civil Supplies in the Atal Bihari Vajpayee government and Minister for Revenue and Muzrai in the Siddaramaiah-led Karnataka government.

He had joined the BJP officially in December 2016 and was elected as MP from Chamarajanagar again in 2019, showcasing his enduring popularity among constituents.

Prasad's demise has plunged the political fraternity and his supporters into mourning. His family members, political associates, and well-wishers are gathering to pay their final respects as his mortal remains are being transported from Manipal Hospital to his residence in Jayalakshmipuram, Mysuru.

The Exhibition Grounds in Mysuru will witness a stream of mourners as Prasad's mortal remains will be kept for public viewing, allowing people from all walks of life to bid farewell to their beloved leader.

Prasad's name had come up in the 'Tehelka tapes' controversy, after the sting operation by magazine Tehelka to expose defence deals under the Atal Bihari Vajpayee-led NDA government. The tapes showed Samata Party leader Jaya Jaitley allegedly telling an arms dealer to deposit money with Prasad, who was then in Bengaluru. However, Prasad denied these claims, saying he was in Mysuru at the time, and also sued Tehelka for defamation.

Karnataka Chief Minister Siddaramaiah on Wednesday attacked the BJP over the obscene video case in Hassan district by questioning who gave the accused Prajwal Revanna a visa to go abroad. He also hit out at Union Minister Amit Shah asking why did he gave a ticket to Hassan JD(S) MP Prajwal, who is the accused in the sex scandal case. 

He alleged that former Prime Minister and JD(S) supremo H D Deve Gowda planned the escape of his grandson and Hassan MP Prajwal Revanna abroad. 

“Who gives passport and visa for travelling abroad? It’s the Centre. Can he go without the Centre’s knowledge? It was former Prime Minister H D Deve Gowda who planned and sent him abroad,” the Chief Minister said.

"Prajwal pen drives case is not related to DCM DK Shivakumar. Why did Amit Shah give a ticket to the accused of a sex scandal?" he questioned.

Siddaramaiah also wrote to Prime Minister Narendra Modi requesting him to direct the Ministry of External Affairs and Ministry of Home Affairs to cancel the Diplomatic Passport issued to Prajwal Revanna and ensure his return to face the law.

Prajwal is accused in an alleged sex scandal which is under investigation by a Special Investigation Team (SIT) constituted by the Karnataka government. He is believed to have escaped to Germany shortly after polling in the first phase of elections in the state got over on April 26, in which Prajwal was the JD(S)-BJP combine's candidate from Hassan. 

The Karnataka CM said that SIT will conduct an investigation in a transparent manner in the case.

Earlier, Siddaramaiah wrote on X, "The government has decided to form a special investigation team in connection with Prajwal Revanna's obscene video case. Obscene video clips are circulating in Hassan district, where it appears that women have been sexually assaulted."

New Delhi: Even though Prime Minister Narendra Modi's nasty election speech in Rajasthan's Banswara has triggered a nationwide controversy, the Election Commission has so far not taken any action. Meanwhile the Opposition bloc INDIA called the speech an attempt to divert attention from "real issues".

Addressing the people Banswara, on April 21, (Sunday) Modi openly attacked India’s Muslims, suggesting they were “infiltrators” and went on to claim that the opposition if elected would give away “mangalsutras” and “land” of those listening to his speech to them (Muslims). 

He referred to his immediate predecessor, Dr Manmohan Singh who was in office for 10 years as prime minister till 2014, and said, “Earlier, when his government was in power, he had said that Muslims have the first right on the country’s property, which means who will they collect this property and distribute it to – those who have more children, will distribute it to the infiltrators. Will the money of your hard work be given to the infiltrators? Do you approve of this?” 

Modi went on to say, “This Congress manifesto is saying that they will calculate the gold of the mothers and sisters, get information about it and then distribute it. Manmohan Singh’s government had said that Muslims have the first right on property. Brothers and sisters, these urban Naxal thoughts will not let even your mangalsutra escape, they will go this far.”

Narendra Modi and the BJP so far in their campaign trail have invoked religious faith, the Ram temple and Lord Ram multiple times, directly using it to call for people to vote for them. The Election Commission has been completely silent on the messaging via videos, tweets and other exhortations. 

Did Manmohan Singh really say that?

Modi’s claim that Dr Singh said that is not new and was refuted in 2006 itself by Singh’s PMO, when Modi had first made the false claim. The PMO had termed such remarks, “a deliberate and mischievous misinterpretation of what the Prime Minister said here yesterday at the meeting of the National Development Council, on fiscal priorities of the government.” It was termed “an avoidable controversy has been generated. The Prime Minister’s observations have also been quoted out of context in some sections of the electronic media, fuelling a baseless controversy.”

The full text of the paragraph in which the Prime Minister referred to the issue of minority empowerment to clarify the matter is as follows:

“I believe our collective priorities are clear: agriculture, irrigation and water resources, health, education, critical investment in rural infrastructure, and the essential public investment needs of general infrastructure, along with programmes for the upliftment of SC/STs, other backward classes, minorities and women and children. The component plans for Scheduled Castes and Scheduled Tribes will need to be revitalized. We will have to devise innovative plans to ensure that minorities, particularly the Muslim minority, are empowered to share equitably in the fruits of development. They must have the first claim on resources. The Centre has a myriad other responsibilities whose demands will have to be fitted within the over-all resource availability.”

The PMO’s clarification said. “it will be seen from the above that the Prime Minister’s reference to “first claim on resources” refers to all the “priority” areas listed above, including programmes for the upliftment of SCs, STs, OBCs, women and children and minorities.

Opposition reacts

Chairman, Media and Publicity department of the Congress, Pawan Khera said in a video message in a post, “We challenge the Prime Minister to show us if the word Hindu or Muslim is written anywhere in our manifesto. This kind of lightness is there in your mentality, in your political values. We have talked about justice for the youth, women, farmers, tribals, middle class and workers. Do you object to this as well?”

Khera was referring to earlier mistruths uttered by Modi about the “Muslim League” having influenced the Congress manifesto.

In Jharkhand’s Ranchi at an opposition rally, Congress president Mallikarjun Kharge is reported to have said by BBC Hindi, “If democracy and the Constitution end in the country, then the people will have nothing left. Babasaheb Ambedkar ji and Jawaharlal Nehru ji gave equal voting rights to everyone, due to which all classes got respect. But Narendra Modi wants to snatch their rights from the poor.”

B.V. Srinivas termed it as unfortunate that “this person is the Prime Minister of this country, and an even bigger tragedy is that the Election Commission of India is no longer alive.” He said that “due to the frustration of impending defeat, the Prime Minister of India is openly sowing the seeds of hatred, he is polarising by misquoting Manmohan Singh’s 18-year-old incomplete statement, But the Election Commission (Modi ka parivar) is bowing down.”

Modi’s past hate-speech

Modi, in his 12-year tenure as chief minister of Gujarat was known to have made speeches targeting the state’s minority Muslim community brazenly, terming camps where Muslims were forced to stay in after communal violence gripped the state in 2002. Frontline covered him on his Gujarat Gaurav Yatra started shortly after the violence, at a rally at Becharaji in Mehsana district in northern Gujarat, when he said, “What should we do? Run relief camps for them? Do we want to open baby-producing centres? But for certain people that means hum paanch, hamare pachees.” 

In 2017 it was time again for direct speech targeting Muslims when in February he spoke of ‘shamshaan versus kabristan’ campaigning for UP and then for Gujarat elections when the BJP had its worst performance this millennium, in a speech at Palanpur on December 10, 2017 Modi invoked a “secret meeting” to get Pakistan to fix Gujarat’s assembly polls. He said that a meeting was held at Congress leader Mani Shankar Aiyar’s residence, attended by former PM Manmohan Singh, former Vice-President Hamid Ansari, former Army Chief Deepak Kapoor and distinguished diplomats to execute the plot. Modi’s PMO faced embarrassment when in response to an RTI filed by the Congress, his office was forced to say that Modi’s campaign speech could have been based on an “informal input”.

In the only question he has answered as part of a press conference with Joe Biden on June 22, 2023, Modi was asked, “India has long prided itself as the world’s largest democracy, but there are many human rights groups who say that your government has discriminated against religious minorities and sought to silence its critics.  As you stand here in the East Room of the White House, where so many world leaders have made commitments to protecting democracy, what steps are you and your government willing to take to improve the rights of Muslims and other minorities in your country and to uphold free speech?”

In response Modi appeared visibly frazzled and denied all charges. “I’m actually really surprised that people say so.  And so, people don’t say it.  Indeed, India is a democracy.” 

The journalist was trolled online by BJP leaders and supporters to such an extent that the White House had to come out and defend her and strongly denounce the trolling and abuse.
