Next-gen seawater batteries stand 380,000 charging cycles, could replace li-ion

As the push for renewable energy intensifies, the demand for effective electricity storage solutions becomes increasingly critical.

Current lithium-ion batteries, commonly used in electric vehicles and portable electronics, are hitting their limits.

According to Xiaolei Wang, a chemical engineering professor at the University of Alberta, these batteries are not well-suited for large-scale energy storage required for the electrical grid.

Survives 380,000 charging cycles Wang and his research team are focusing on an innovative approach to battery technology: grid-level aqueous batteries that utilize seawater as an electrolyte.

Collaborating with the Canadian Light Source at the University of Saskatchewan, this approach could lead to safer, more affordable, and environmentally friendly alternatives to traditional lithium-ion batteries.

Aqueous batteries have been hampered in development mainly due to the absence of suitable materials for anodes, the battery components where electricity flows out.

However, Wang’s team has overcome this challenge by developing a new type of anode material.

This material combines polymer nanosheets with carbon nanotubes, making it capable of storing diverse ions, including those found in seawater.

One of the key advantages of this new anode design is its thickness, which allows for a significantly higher energy storage capacity.

These anodes are incredibly durable, sometimes enduring up to 380,000 charging cycles.

Wang points out that they are also capable of operating efficiently in extreme conditions, including rapid charging and discharging or at low temperatures.

New seawater battery tech The importance of the advanced synchrotron light facility at the Canadian Light Source cannot be overstated.

This facility was crucial in analyzing the microstructure of the anode material and understanding its electrochemical properties.

“Our success is largely thanks to the resources provided by the CLS,” Wang notes.

The potential impact of this new technology is significant. Aqueous batteries based on this innovative anode could enable broader energy storage solutions, expanding the potential for renewable energy usage.

Wang emphasizes that Canada is rich in renewable energy resources. If this new battery technology can effectively capture and store that energy, it could lead to reliable, safer, and more accessible energy storage options for everyone.

Developing new battery technologies is essential as the world shifts towards more sustainable energy sources.

Reliably storing energy generated from solar and wind power sources is crucial for ensuring a stable energy supply, especially when these sources are not producing electricity.

Wang’s research could represent a significant step forward in battery technology, moving away from the limitations of lithium-ion batteries.

These new aqueous batteries might be more suited to meet future energy storage needs by harnessing materials that can work with seawater.

The ongoing research into aqueous batteries could be a game changer for the energy landscape.

As teams like Wang’s work to refine and scale this technology, the promise of a cleaner, more efficient energy system becomes more attainable.

Innovative battery solutions will play a critical role in facilitating that transformation in a future where renewable energy is dominant.

This is how cheap solar in the right places can be. Look at Australia’s insolation...

https://solargis.com/resources/free-maps-and-gis-data?locality=australia-and-oceania

That outback has enough insolation to power the whole planet multiple times over. Not just electricity ALL energy use. That giant thermonuclear reactor in the sky hits Australia with 6+ kWh per day part a meter over a continent sized area. It’s measured in petajoules or exajoules numbers so large mouth breathers struggle to even visualize them.

Solar is so cheap when it comes to raw electrons you can string a 4000+ km high voltage DC cable across oceans and still sell it at reasonable retail prices. This should squash any nonsense that you cannot send power long distances HVDC could make a global energy network even over links of 10,000km at a million plus volts the losses are acceptable when you have sub $10 per MWh electrons.

This is a whole new world its the 21st century not the 1800s with coal and steam ships. Only the Indians and Chinese subjugated populations will tolerate the air and water pollution of air fired coal combustion it is, and never was, or will be clean. Even with huge 100 million dollar sized scrubbers it cannot due to physics be as clean as gas. Only the lack of the people ability to force the government and their corporations to clean up stack exhaust is why India and China have coal plants if they had to be as clean as gas turbines they couldn’t do so and would be shut down , right fully so. Coal is best left in the dust bin of 19th century history. No love lost with any real environmental or atmospheric scientist who can do freshman level chemistry and math the on the stack exhaust products and ash piles.

I agree with you 100% on the physical science of solar. But the political science of solar isn't good. No one should demand solar be on the grid with the idea that it'll placate the eco-Nazi Dims. The Dims will try to ban solar as soon as the grid starts depending on it.

For example, in Australia they're starting to impose a "sun tax" on home solar users who put power onto the grid. Even though the left there pushed for people to get solar in part to help the grid, now the left is punishing people for it. There is simply no pleasing the left.

Therefore, IMHO it's best to do solar in a self-contained environment (decentralized solar). For the past 2 years I've been selling power to the grid (unlike the first 2 years I had solar). I have the means to change a configuration setting on my inverter and quit selling power to the grid if the regulations change against me. I spent a little extra for inverters with the feature to disable the grid sell feature, for the sole purpose of me having the final say on if my solar can be regulated by the grid regulators. If the regulations are in my favor to sell a little power to the grid, fine. If the regulations change and make it not in my favor, that's fine too.

Last year I put 4,208 kWh onto the grid, and pulled 4,386 kWh from the grid (pulling a net 178 kWh from the grid across the entire year).

You are a lobbyist and a liar ( redundant )

"Actually, Texas's energy storage capacity is impressive, but it doesn't quite reach 83,000 megawatt-hours. As of late 2024, Texas had around 9.3 gigawatts (GW) of installed battery storage capacity. This capacity has grown significantly in recent years, making Texas one of the leaders in energy storage in the U.S., second only to California1.

If you're curious about how this storage supports the grid or its role in renewable energy, let me know!"

Texas has an expensive and overly complitcated power grid. Texas should be ashamed. IMO This situation is an economic and national security threat.

Leaches make money off of the hocus-pocus.. So there is that.

All of the money os wind solar and "Storage" ( joke ) could have been spent on clean coal,. NG and nuclear power plants.

I have posted the links to the facts. You are the one who has no leg to stand on. Your opinion is just that an opinion and a wrong one at that. U don’t argue with people who don’t have facts, figures or peer reviewed science to back their point.

If you.choose to be ignorant that’s on you. Stay in Virginia where that kind of thing is common in the backwards hills. I can hear the banjos already.

Fact is Texas is leading the nation in energy of all forms. We have competitive rates today right now you can sign up for 10.3 cents per kWh flat rate power that’s some of the most competitive in the nation.

Http://Powertochoose.org

That’s the public clearing house for retail power providers on ERCOT. At the biz level with a TIN number power can be had in the five cent range. Yeah we have soooo expensive power and should be ashamed. Mind you Republicans have had one party rule in Texas for 20+ years.

Texas is just fine ,please don’t come here we don’t need more yankee foreigners with bad opinions and worse sense.
