The new high-capacity lithium-sulfur batteries can pave way for cheaper electric cars and solar grids.

Researchers have developed a new solution that is capable of powering smartphones for five continuous days or electric cars to run over 1,000 km without needing to refuel.

The new battery solution does away with the traditional lithium-ion combination in modern batteries that power devices such as smartwatches, smartphones, and even pacemakers. Instead, researchers used lithium-sulfur batteries to achieve ultra-high capacity.

Researchers at Australia-based Monash University said the team could re-configure the design of sulfur cathodes using the existing materials in standard lithium-ion batteries. The reconfiguration helped researchers achieve higher stress levels without registering any drop in overall capacity or performance.

0135AE83-8371-4134-A67C-20F351B50928

Tesla has made a lot of battery moves this year and it is closing the year by filing a patent on a new chemistry for better, longer-lasting and cheaper batteries.

Earlier this year, we reported on Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University, unveiling the impressive results of tests on a new battery cell that could last over 1 million miles in an electric vehicle.

The new battery tested is a Li-Ion battery cell with a next-generation “single crystal” NMC cathode and a new advanced electrolyte.

Since then, Tesla has been filing US and international patents on the new battery chemistry.

The U.S. energy storage market is expected to grow by a factor of 12 in the next five years, from 430MW deployed in 2019 to more than 5GW and a value of more than $5 billion by 2024, says Wood Mackenzie Energy Storage Service.

Tesla and GM are making big bets on lithium-ion batteries for energy storage systems and electric vehicles, but billionaire investors and venture capital firms are investing in competing battery technology, such as flow batteries.

Breakthrough Energy Ventures, the group of private investors led by Bill Gates and fellow billionaires Jeff Bezos, Michael Bloomberg, Richard Branson and Jack Ma, invested in iron-flow battery maker ESS in November.

ESS, which makes long-duration, iron flow batteries, secured $30 million in a Series C investment round from Breakthrough Energy Ventures (BEV), the group of private investors led by Bill Gates and fellow billionaires Jeff Bezos, Michael Bloomberg, Richard Branson and Jack Ma, among others.

Although electric cars haven’t quite taken off in the 2010s the way some had anticipated, sheer economics are pointing to the 2020s as the time when EVs will find that market fever pitch.

From 2010 to 2019, lithium-ion battery prices (when looking at the battery pack as a whole) have fallen from $1,100 per kilowatt-hour to $156/kwh—an 87% cut. From 2018 to 2019 alone, that represents a cut of 13%.

Those numbers were part of an annual report released Tuesday by Bloomberg New Energy Finance (BNEF). The report also suggested that we’ll reach the $100/kwh mark earlier than it had previously anticipated—by 2023.

Scientists develop superfast-charging, high-capacity potassium batteries

A7A8A7FA-B1DA-4458-8F56-D77017F88676

Skoltech researchers in collaboration with scientists from the Institute for Problems of Chemical Physics of RAS and the Ural Federal University have shown that high-capacity, high-power batteries can be made from organic materials without lithium or other rare elements. In addition, they demonstrated the impressive stability of cathode materials and recorded high energy density in fast charge/discharge potassium-based batteries. The results of their studies were published in the Journal of Materials Chemistry A, the Journal of Physical Chemistry Letters and Chemical Communications.

Lithium-ion batteries are widely used for energy storage, particularly in portable electronics. The demand for batteries is surging due to the rapid advancement of electric vehicles with high requirements for lithium. For example, Volvo intends to increase the share of electric vehicles to 50 percent of its overall sales by 2025, and Daimler announced its plans to give up internal combustion engines altogether, shifting the emphasis to electric vehicles.

Gas plants will get crushed by wind, solar by 2035, study says

136BB5A5-8131-49A9-885D-D3AABF450FCE

Generators now on drawing boards will be left uneconomical

Natural gas-fired power plants, which have crushed the economics of coal, are on the path to being undercut themselves by renewable power and big batteries, a study found.

By 2035, it will be more expensive to run 90% of gas plants being proposed in the U.S. than it will be to build new wind and solar farms equipped with storage systems, according to the report Monday from the Rocky Mountain Institute. It will happen so quickly that gas plants now on the drawing boards will become uneconomical before their owners finish paying for them, the study said.

The development would be a dramatic reversal of fortune for gas plants, which 20 years ago supplied less than 20% of electricity in the U.S. Today that share has jumped to 35% as hydraulic fracturing has made natural gas cheap and plentiful, forcing scores of coal plants to close nationwide.

Renewables meet 50% of electricity demand on Australia’s power grid for first time

A59EECBC-442D-4498-93D6-E3BB446C510A

For a brief moment solar, wind and hydro combined to deliver more than half the power into the National Electricity Market

Australia’s main electricity grid was briefly powered by 50% renewable energy this week in a new milestone that experts say will become increasingly normal.

Data on the sources of power in the National Electricity Market showed that at 11.50am on Wednesday, renewables were providing 50.2% of the power to Queensland, New South Wales, Victoria, Tasmania and South Australia – the five states served by the market.

How cheap must batteries get for renewables to compete with fossil fuels?

8B238BD5-F4BD-40BD-84F1-E244C60118AE

Production of lithium batteries for environmentally friendly electric cars future of energy

 While solar and wind power are rapidly becoming cost-competitive with fossil fuels in areas with lots of sun and wind, they still can’t provide the 24/7 power we’ve become used to. At present, that’s not big a problem because the grid still features plenty of fossil fuel plants that can provide constant baseload or ramp up to meet surges in demand.

But there’s broad agreement that we need to dramatically decarbonize our energy supplies if we’re going to avoid irreversible damage to the climate. That will mean getting rid of the bulk of on-demand, carbon-intensive power plants we currently rely on to manage our grid.

Alternatives include expanding transmission infrastructure to shuttle power from areas where the wind is blowing to areas where it isn’t, or managing demand using financial incentive to get people to use less energy during peak hours. But most promising is pairing renewable energy with energy storage to build up reserves for when the sun stops shining.

The approach is less complicated than trying to redesign the grid, say the authors of a new paper in <emJoule, but also makes it possible to shift much more power around than demand management. A key question that hasn’t been comprehensively dealt with, though, is how cheap energy storage needs to get to make this feasible.

First fully rechargeable carbon dioxide battery is seven times more efficient than lithium ion

B76D6966-742D-4972-BE5E-8F2914D2158A

 Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. Until now, however, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.

Researchers at the University of Illinois at Chicago are the first to show that lithium-carbon dioxide batteries can be designed to operate in a fully rechargeable manner, and they have successfully tested a lithium-carbon dioxide battery prototype running up to 500 consecutive cycles of charge/recharge processes.

Their findings are published in the journal Advanced Materials.

Tesla battery researcher unveils new cell that could last 1 million miles in ‘robot taxis’

E1B67386-E015-4D1E-A17B-EF8D738CE355

Tesla’s battery research partner has released a new paper on a battery cell that could last over 1 million miles, which they say is going to be particularly useful in ‘robot taxis’ — something that Tesla wants to bring to market.

When talking about the economics of Tesla’s future fleet of robotaxis at the Tesla Autonomy Event, Tesla CEO Elon Musk emphasized that the vehicles need to be durable in order for the economics to work:

The cars currently built are all designed for a million miles of operation. The drive unit is design, tested, and validated for 1 million miles of operation.

But the CEO admitted that the battery packs are not built to last 1 million miles.

Lamborghini Sián: The world’s first supercapacitor-hybrid supercar

81EC609D-BC49-4AAD-94ED-5DA035261A01

Sensual curves meet jagged angles in the remarkable Sian, Lamborghini’s first hybrid and the first car in production history to use a supercapacitor hybrid system

Lamborghini has chosen a radically different way of dipping its toe in the waters of hybridization with the announcement of its new Sián, which couples a screaming, naturally aspirated V12 engine with a supercapacitor-based secondary electric system.

Supercapacitors, as opposed to batteries, offer a unique set of advantages and drawbacks to automakers. They have enormous charge and discharge rates, meaning they can put out huge amounts of power, charge up almost instantly, and pull in a much larger amount of energy through things like regenerative braking, in which a battery’s ability to accept charge becomes a limiting factor. They also don’t deteriorate over time, maintaining their performance over millions of cycles.
