Be it smartphones, notebooks or electric cars, lithium-ion batteries have revolutionized our world, laying the foundation for a wireless, fossil fuel-free society, the Royal Swedish Academy of Sciences said on Wednesday while awarding the 2019 Nobel prize in Chemistry to John Goodenough, Stanley Whittingham and Akira Yoshino.

The Li-ion technology is currently the best performing technology for energy storage based on batteries. Li-ion batteries are used in small electronics (smartphones, laptops etc) and are also the best options for electric cars.


In the 1970s as the world stared at oil crisis, Whittingham from Binghamton University in the US, American professor and solid-state physicist Goodenough (currently at the University of Texas at Austin) and Japanese chemist Yoshino advanced the development in the field through the 1980s.

Since Lithium is the lightest metal, using lithium ions made batteries lighter.

The lithium-ion batteries were launched commercially by Sony and Asahi Kasei Corporation in 1991.

Today, the race is on among the stakeholders to find a battery that can let users enjoy time on their devices without worrying about the charge.

Researchers from the University of Alberta recently developed a new battery technology that could provide 10 times more charge capacity compared to the lithium-ion power packs.

This battery technology utilizes silicon nanoparticles as an electrode for the lithium-ion batteries. Silicon is abundant, and the substance only costs around a third of the price of high-purity graphite, which sells for more than $10,000 per metric ton.

Going forward, smartphones will sport graphene batteries that charge swiftly, and will mark a quantum leap from the fast charging technologies and the current default of lithium-ion batteries.

When it comes to electric cars, Elon Musk-run Tesla has achieved great deal of efficacy in this field and is now aiming to create a lithium-ion battery that can run a car or an electric truck for over 16 lakh kms.

Current Tesla cars can achieve about 8 lakh kms out of their batteries before they face any serious problem.

A new research paper from Dalhousie University in Nova Scotia, Canada has claimed the Jeff Dahn-led team is close to creating a lithium-ion battery that can run a car for over 1 million (over 16 lakh) miles.

For more than a decade, Tesla engineers have been obsessed with making the world’s most efficient electric vehicles.

As a result, Tesla vehicles already travel farther on a single charge than any other production EV on the market.

Model S and Model X cars can achieve nearly 600 kms and 525 kms per charge on a 100 kWh battery pack.

Tesla’s choice of cylindrical cells sets it apart from other EV players. The company also uses a liquid-cooled thermal management system to manage battery temperatures whereas other automakers take a more economical air-cooling approach.

By adjusting the temperature of the battery pack, Tesla is able to ensure that cells are operating in their most efficient and optimal states, thereby maximizing battery longevity as well as performance.

It has been argued that lithium will be one of the main objects of geopolitical competition in a world running on renewable energy and dependent on batteries.

Current research areas for lithium-ion batteries include life extension, energy density, safety, cost reduction and charging speed, among others.

Research has also been under way in the area of non-flammable electrolytes as a pathway to increased safety based on the flammability and volatility of the organic solvents used in the typical electrolyte. (IANS)

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment.

By Prerana Agarwal Saxena

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment. While everyone is making their big fat Indian wedding dreams come true, they are also adding their carbon footprint and undue energy consumption. Modern couples are now looking for ways to have a wedding with a sustainably conscious mindset. It's become about incorporating less waste, locally sourced and seasonal food, natural materials over the use of plastic. Mindful wedding planning and decor includes the use of recycled paper and goods along with eco-friendly venue needs. Check out this quick guide to achieve a sustainably conscious wedding without compromising on luxury:

Choose locally sourced material to uplift artisans
Sustainable can be luxurious too, incorporate some native flavour into the decor and theme. With the use of locally sourced materials and local artisans coming into play, the wedding instantly becomes sustainable. Include the work of local vendors ensure minimal packaging requirements, thus saving on unnecessary plastic and lamination. It also decreases the need for transporting elements from other cities and hence lowers the carbon footprint. For instance, at one of our weddings, we made use of sand art for a setup in Jodhpur. This helped promote local work while also being environmentally friendly with zero wastage of other materials. In another instance from Rajasthan, the traditional glass-blown technique was used to build decor items while giving a cultural touch to the destination wedding.

The vaccination was administered from 7 a.m. till 7 p.m. and the compiled data was made available late at night.

The Tamil Nadu health department has administered 16,43,879 lakh doses of vaccine in the second mega vaccination camp organised by it. The state public health department in a statement on Sunday said that this has taken the total vaccination to one crore since the beginning of September till date. The vaccination was administered from 7 a.m. till 7 p.m. and the compiled data was made available late at night.

The health department officials also said that as the state has almost exhausted its quota of vaccines, there would not be any vaccines on Monday. Regular vaccination will resume after the vaccine supplies arrive from New Delhi, officials said. The state health department had expected to vaccinate 15 lakh people on Sunday in 18,824 centres spread across primary health centres, anganwadis, noon meal centres, government hospitals, schools and some auditoriums.

Hanisha Kapoor, COO, ArchiesBeauty.com shares makeup trends experimented by these Bollywood divas throughout 2021 for inspiration.

Festivals are just around the corner and while you brainstorm about OOTDs (outfit of the day), don't forget the right makeup. Hanisha Kapoor, COO, ArchiesBeauty.com shares makeup trends experimented by these Bollywood divas throughout 2021 for inspiration. While some stuck to the classics, others mixed it up... take a look:

The Classic Red Lip
We don't see a future where classic red lips go out of fashion. The right way to achieve this celebrity look is to focus on accentuating your lips and keeping the rest of the face minimal. Give your lips a good scrub to plump them, moisturize and follow it up with a red lip liner to define the shape of your lips. Now go on with the perfect shade of red and finish your look with a slick of eyeliner, minimal concealer, and foundation.
