  High-tech cameras to catch drivers on their phones could be mobile The government insists the technology, which captures clear and accurate photos in all weather conditions, will be introduced in Queensland soon - although it has not committed to a time frame for the roll-out. An "astounding" number of law-breakers, more than 100,000 in just three months, have been caught by the cameras in NSW, according to Bernard Carlon from the NSW Road Safety Centre. © Supplied This man was captured speaking on the phone. © Supplied This driver was captured texting with a passenger beside him.

Police negotiate with person hanging 10 metres from Story Bridge in Brisbane

  Police negotiate with person hanging 10 metres from Story Bridge in Brisbane Police are trying to negotiate with a person hanging on a harness 10 metres from the underside of Brisbane’s Story Bridge as peak hour traffic builds. Officers were called to the bridge just after 5:50am to find a person swinging from a makeshift harness about 10 metres below.The left lane inbound on the Story Bridge was closed but has since seen reopened as officers attempt to speak with the person.Queensland Ambulance Service medical director Dr Stephen Rashford photographed the scene, describing it as "a waste of valuable emergency services".

Lithium - ion batteries are the workhorses of modern-day gadgets; they ' re found in everything from smartphones to jumbo jets to the Tesla Model S. They are typically made with two layers of material, called the anode and the cathode, separated by an electrically conducting fluid. Lithium ions start off

The prizes come with a $918,000 cash award, a gold medal and a diploma.

Since entering the market in 1991, lithium-ion batteries have "laid the foundation of a wireless, fossil-fuel-free society, and are of the greatest benefit to humankind," the Nobel committee said in a statement. 

When were lithium-ion batteries created?

Stanley Whittingham, a distinguished professor of chemistry at Binghamton University, created the foundation of the lithium-ion battery in the 1970s during the oil crisis. Although that battery could hold up to 2 volts of energy (most modern batteries are 1.5 volts), it was too explosive to be viable, the Nobel committee said.

In 1980, John B. Goodenough of the University of Texas-Austin, created a component better at handling lithium ions, or charged lithium atoms that have lost one of their three electrons.This led to more powerful batteries. 

Pioneers of lithium-ion battery win 2019 Nobel chemistry prize

  Pioneers of lithium-ion battery win 2019 Nobel chemistry prize Scientists John Goodenough, Stanley Whittingham and Akira Yoshino won the 2019 Nobel Prize for Chemistry on Wednesday for the development of lithium-ion batteries, an important technology in enabling the world to move away from fossil fuels. American Goodenough, at 97, becomes the oldest winner of a Nobel prize. He shared the award equally with Whittingham from Britain and Yoshino of Japan."This rechargeable battery laid the foundation of wireless electronics such as mobile phones and laptops," the Royal Swedish Academy of Sciences said in a statement on awarding the 9 million Swedish crown ($906,000) prize.

Lithium - ion batteries are often in the news for terrible reasons, but the problems go Lithium - ion batteries have been making headlines for all the wrong reasons. But unlike most mature tech , they seem to get more volatile as time goes on. That's because we demand higher -capacity batteries in

Five years later, Akira Yoshino of Asahi Kasei Corp. and Meijo University in Japan, created the first commercially viable lithium-ion battery.

How do they work?

According to the Department of Energy, a lithium-ion battery has an anode and a cathode,  or electric conductors we know as the "-" and "+" ends of a battery, that store lithium; an electrolyte and a separator that help in the distribution of lithium ions through the battery; and collectors for positive and negative electrical currents. 

When a lithium-ion battery discharges, a flow of ions is created from the anode to the cathode, generating power. When you charge the battery, the flow reverses from the cathode to the anode.

A critical piece of modern technology

The development of the lithium-ion battery was revolutionary in the tech world, powering devices such as mobile phones and laptops. The batteries last much longer because users  can recharge them hundreds of times.

"The advantage of lithium-ion batteries is that they are not based upon chemical reactions that break down the electrodes, but upon lithium ions flowing back and forth between the anode and cathode," the committee said.

The batteries have been used to store energy for solar and wind power, which the committee said is critical to moving away from fossil fuels.

One of the big issues with lithium-ion batteries is their tendency to overheat, said the Clean Energy Institute based at the University of Washington. "Because of the risks associated with these batteries, a number of shipping companies refuse to perform bulk shipments of batteries by plane," the CEI said.

The batteries help power electric vehicles

Lithium-ion batteries have become crucial to the deployment of electric vehicles, ranging from the Tesla Model 3 to the Chevrolet Bolt to the Nissan Leaf.

Unlike hybrid cars, which typically use nickel-metal hydride batteries, electric cars use higher-performance lithium-ion batteries. Their high power-to-weight ratio, energy efficiency and temperature control are particularly useful for transportation purposes, according to the Department of Energy.

Although prices have come down significantly, electric vehicles remain more expensive than gasoline-powered cars because of the costs associated with lithium-ion batteries. International Trade Commission analysts projected that electric car costs would fall to the same level as conventional vehicles by 2025 or 2030, according to a report published in December.

In the long term, electric vehicles could graduate to other power storage technologies, such as solid-state batteries or lithium-air batteries, experts said.

The two Americans Christina Koch and Andrew Morgan exchanged old batteries for new and more powerful lithium-ion batteries on the outer wall of the ISS. After more than six hours of successful outdoor use, the two astronauts returned to the interior of the ISS.
