Hyderabad, Oct 8 Burning a candle could be all that it takes to make an inexpensive but powerful electric car battery, researchers from the Indian Institute of Technology in Hyderabad have found.

The research revealed that candle soot could be used to power the kind of lithium-ion battery that is used in plug-in hybrid electric cars.

“We are very excited about the results. This new approach is very easy and the costs involved are minimal — it would make battery production cheaper,” said Chandra Sharma, one of the study authors.

Sharma estimated that one hybrid car would need ten kg of carbon soot, which would be deposited in about an hour using candles.

Their discovery opens up the possibilities of using carbon in more powerful batteries, driving down the cost of portable power.

Lithium-ion batteries power many devices, from smartphones and digital cameras all the way up to cars and even aircraft.

The batteries work by having two electrically-charged materials suspended in a liquid to produce a current.

Carbon is used as one of those materials in smaller batteries, but for bigger, more powerful batteries — such as those used in electric cars — carbon is not suitable because of its structure, which cannot produce the required current density.

In the new study, Sharma and Manohar Kakunuri found that because of the shape and configuration of the tiny carbon nanoparticles, the carbon in candle soot is suitable for use in bigger batteries.

What is more, because the soot could be produced quickly and easily, it is a scalable approach to making batteries.

When a candle burns, it gives off clouds of black soot made of carbon.

The researchers looked at the soot collected from the tip of a candle flame and from the middle of the flame and compared the size, shape and structure of the carbon.

The results showed that the burning process forms nanoparticles of carbon that are 30-40 nanometres across and are joined together in an interconnected network.

They also found that the soot recovered from the tip of a candle flame, which burns at 1400 degrees Celsius, has fewer impurities like wax, making it perform better as an electrical conductor.

In tests, the researchers found the soot effective as a conducting material in a battery.

The researchers now plan to develop a candle soot battery to test the technology further.

The findings appeared in the journal Electrochimica Acta.

New Delhi, September 16, 2017 : It can be rightly believed that one could just depend on two things in life – taxes and death. But times have changed and circumstances are different today. In the present situation, there are three things; taxes, demise and the cost of oil spiraling everlastingly upwards.

With the gas costs proceeding to move high and higher, expanding your car’s fuel mileage is the most ideal approach to ensure your wallet. Read on to know how!

  1. Driving Habits

  • Back off. The speedier you move, the harder your motor needs to work to push through the air. Speeding can decrease fuel proficiency by up to 33%. (Factors other than air resistance diminish mileage below around 60 mph (97 km/h), so efficiency is not motivation to go slower, but rather mileage diminishes quickly over that speed).
  • Accelerate smoothly with direct throttle. Motors are most proficient with decently high wind current (throttle) and at revolutions per moment (RPM)s up to their energy crest. You should hone ‘short shifting’, or changing to higher gears when you achieve your coveted speed by skipping middle riggings.
  • Abstain from braking wherever possible. Braking wastes vitality from fuel that you have effectively consumed, and accelerating in the wake of braking expends more fuel than driving at a consistent speed.
  1. Tyre Essentials

  • Check your tyre weights consistently – you can make it a part of your Sunday schedule. All motoring magazines reveal to you a similar thing and that is on purpose – In the event that your tyre weights are low, you will be expanding the moving resistance of the tyre and that will be ransacking your fuel effectiveness – your gas mileage will be down. Appropriately inflated tyres can diminish fuel utilization by up to 3. Having appropriately swelled tires will additionally enable you to maintain safety against uneven wear on the tread.
  • Select the narrowest tyres for your vehicle that will fulfill your driving style and requests. Slender tyres have less frontal range, consequently lessening streamlined drag. Use the size of tyres that came stock on the vehicle- special emphasis should be paid to not use a tyre that is contradictory with your wheels. You may use smaller wheels only if your car producer supports.
  1. An In-order Engine

An appropriately tuned engine augments control and can incredibly upgrade fuel effectiveness. You must make sure of all the functions of your car; from keeping great spark plugs, changing the oil on time, ensuring the air filter clean, and so on.

  1. Lighten Your Car Weight

  • Weight is one of the greatest foundations for loss of motor vitality in non-mixture autos. Generally, additional 50 kg builds fuel utilization by 1– 2%.
  • Get the lightest car that will serve your necessities. On the off chance, the seats that you don’t utilize can be evacuated. If you utilize your trunk as a storage room for substantial things, discover somewhere else for them.
  1. Fuel

  • When you top off with gas, fill up midway and attempt to keep your tank over one quarter full. You could put influence on the fuel pump on the off chance that your fuel runs short. However, 10 gallons (which is an equivalent of 37.9 L) of fuel includes additional approximately 17.5 kg of weight. A tank that has been filled till half the capacity may build your mileage.
  • Purchase quality fuel. Remember that while “discounted” fuel may spare you a couple of rupees for every L or Gal, it can contain a higher level of ethanol, which consumes at a quicker rate. For better yield out of your cash, look at the mileage between fuel organizations and see what is best for your car.

Practically speaking, in case you religiously adhere to the above focuses (from an administration of previously undertaking nothing specific or common), you should hope to see a mpg change of around 15% which is completely conceivable. If you at present drive quite forcefully, or at high speeds, much more noteworthy increases may be conceivable. That would be uplifting news for both your carbon impression and your wallet.

  • The researchers described a process by which tiny diamonds curtail the electrochemical deposition called plating
  • We anticipate the first use of our proposed technology will be in less critical applications
  • Battery buildups called dendrites  are one of the main causes of lithium battery malfunction

USA, August 28, 2017: Researchers have found that tiny diamonds (diamond particles 10,000 times smaller than the diameter of a hair) can prevent short-circuits and fires in lithium batteries widely used in various mobile devices from smartphones to laptops.

The new process that uses tiny diamonds can turn electrolyte solution – a key component of most batteries into a safeguard against the chemical process that leads to battery-related disasters.

In the study, published in the journal Nature Communications, the researchers described a process by which tiny diamonds curtail the electrochemical deposition, called plating, that can lead to hazardous short-circuiting of lithium ion batteries.

“We anticipate the first use of our proposed technology will be in less critical applications, not in cell phones or car batteries,” said Yury Gogotsi, Professor at Drexel University Philadelphia Pennsylvania, US.

“To ensure safety, additives to electrolytes, such as nano diamonds, need to be combined with other precautions, such as using non-flammable electrolytes, safer electrode materials and stronger separators,” Gogotsi added.

As batteries are used and charged, the electrochemical reaction results in the movement of ions between the two electrodes of a battery, which is the essence of an electrical current.

Over time, this re-positioning of ions can create tendril-like buildups almost like stalactites forming inside a cave.

These battery buildups, called dendrites, are one of the main causes of lithium battery malfunction.

As dendrites form inside the battery over time, they can reach the point where they push through the separator, a porous polymer film that prevents the positively charged part of a battery from touching the negatively charged part.

When the separator is breached, a short-circuit can occur, which can also lead to a fire since the electrolyte solution in most lithium-ion batteries is highly flammable.

To avoid dendrite formation and minimize the probability of fire, current battery designs include one electrode made of graphite filled with lithium instead of pure lithium.

The use of graphite as the host for lithium prevents the formation of dendrites. But lithium intercalated graphite also stores about 10 times less energy than pure lithium.

The new study showed that mixing nano diamonds into the electrolyte solution of a lithium ion battery slows dendrite formation to nil through 100 charge-discharge cycles.

The finding means that a great increase in energy storage is possible because dendrite formation can be eliminated in pure lithium electrodes.

The discovery is just the beginning of a process that could eventually see electrolyte additives, like nano diamonds, widely used to produce safe lithium batteries with a high energy density, Gogotsi noted. (IANS)
