Technology Lithium-ion batteries: Why they're so valuable in high-tech world
Galaxy S11 or Note 11 might get crazy new tech that can recharge a battery in minutes
Real-life Galaxy Note 10 tests have already shown that the phone's 25W battery charging tech is faster than 30W chargers from competitors. What that means is that you only need just over an hour to recharge the massive battery of the Note 10+ model from empty to 100%. Swap that 25W charger for a 45W one, and charging times will be further reduced. But Samsung has been working on a battery charging breakthrough for several years, and we might finally see it deployed in commercial handsets as soon as next year. If that were to happen, the Galaxy S11 or Note 11 might be able to fully recharge a battery in mere minutes or even seconds.

Y Combinator-backed Holy Grail is using machine learning to build better batteries
For a long, long time, renewable energy proponents have considered advancements in battery technology to be the holy grail of the industry. Advancements in energy storage has been among the hardest to achieve economically thanks to the incredibly tricky chemistry that's involved in storing power. Now, one company that's launching from Y Combinator believes it has found the key to making batteries better. The company is called Holy Grail and it's launching in the accelerator's latest cohort.
The lithium-ion battery is a technological breakthrough that helped its creators earn the Nobel Prize in Chemistry on Wednesday.
"They created a rechargeable world," according to a statement from the Royal Swedish Academy of Sciences, the presenters of the Nobel.
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.
'A rechargeable world':
When were lithium-ion batteries created?
Stanley Whittingham,, 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 ( ), 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.
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?
, 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.
The 40mm Apple Watch Series 5 comes with a new battery design
Apple's latest smartwatch model isn't that different from Series 4, but its 40mm version is apparently hiding a component that's dramatically different from its peers. iFixit has discovered that the smaller Series 5 watch uses a battery encased in metal instead of in black foil pouch like typical lithium-ion batteries. Its larger 44mm sibling is powered by one of those standard batteries. The teardown website found a patent that could explain the change: the new metal casing is apparently more space efficient and can free up valuable real estate for a small device.
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,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.
Pioneers of lithium-ion batteries win the 2019 Nobel Prize in Chemistry
This year's Nobel Prize in Chemistry has been awarded to three scientists credited with the invention of the rechargeable lithium-ion battery. John B Goodenough of the University of Texas at Austin, M Stanley Whittingham of Binghamton University and Akira Yoshino of Meijo University will receive equal shares of the 9m Swedish kronor ($905,000) prize, which was announced today by the Royal Swedish Academy of Sciences in Stockholm. RechargeableRechargeable lithium-ion batteries can be found in pretty much everything from mobile phones to electric vehicles, and can store significant amounts of energy from solar and wind power.
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, experts said.
