SIBs received academic and commercial interest in the 2010s and early 2020s, largely due to lithium's high cost, uneven geographic distribution, and environmentally-damaging extraction process. Unlike lithium, sodium is abundant, particularly in saltwater. 

SIB cells consist of a cathode based on a sodium-based material, an anode (not necessarily a sodium-based material) and a liquid electrolyte containing dissociated sodium salts in polar protic or aprotic solvents. During charging, sodium ions move from the cathode to the anode while electrons travel through the external circuit. During discharge, the reverse process occurs.

Sodium-ion batteries have several advantages over competing battery technologies. Compared to lithium-ion batteries, sodium-ion batteries have somewhat lower cost, better safety characteristics (for the aqueous versions), and similar power delivery characteristics, but also a lower energy density (especially the aqueous versions). 

Companies around the world have been working to develop commercially viable sodium-ion batteries.

In July 2024, the University of Chicago and UC San Diego developed an anode-free sodium solid-state battery that they claimed was cheaper, safer, fast charging, and high capacity.

A research team at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute of the Department of Science and Technology (DST) has developed a super-fast charging sodium-ion battery (SIB) based on a NASICON-type cathode and anode material, that can charge up to 80% in just six minutes and last over 3000 charge cycles.

Australia's Altech is building a 120 MWh plant in Germany.

Germany invested €1.3 million in a sodium-ion project with BASF and Mercedes-Benz.

Altris AB was founded by Associate Professor Reza Younesi, his former PhD student, Ronnie Mogensen, and Associate Professor William Brant as a spin-off from Uppsala University, Sweden launched in 2017 as part of research efforts from the team on sodium-ion batteries. Altris holds patents on non-flammable fluorine-free electrolytes consisting of NaBOB in alkyl-phosphate solvents, Prussian white cathode, and cell production. Clarios is partnering to produce batteries using Altris technology.

BYD in 2023 invested $1.4B USD into the construction of a sodium-ion battery plant in Xuzhou with an annual output of 30 GWh.

Chinese battery manufacturer CATL (world's largest EV battery maker) announced in 2021 that it would bring a sodium-ion based battery to market by 2023. It uses Prussian blue analogue for the positive electrode and porous carbon for the negative electrode. They claimed a specific energy density of 160 Wh/kg in their first generation battery.

Faradion Limited is a subsidiary of India's Reliance Industries. Its cell design uses oxide cathodes with hard carbon anode and a liquid electrolyte. Their pouch cells have energy densities comparable to commercial Li-ion batteries (160 Wh/kg at cell-level), with good rate performance up to 3C, and cycle lives of 300 (100% depth of discharge) to over 1,000 cycles (80% depth of discharge). Its battery packs have demonstrated use for e-bike and e-scooter applications. They demonstrated transporting sodium-ion cells in the shorted state (at 0 V), eliminating risks from commercial transport of such cells.[93] It is partnering with AMTE Power plc (formerly known as AGM Batteries Limited).

The future for sodium-ion batteries is bright, driven by their lower cost, abundance of sodium, and improving performance, making them a strong contender for grid-scale energy storage and budget-friendly electric vehicles. Market growth is projected to be substantial, with forecasts showing significant expansion in annual production and market value over the next decade. Key challenges remain, such as increasing energy density and cycle life, but ongoing research and development are rapidly addressing these issues, and some manufacturers are already producing them for commercial use. 

Renewable energy surpassed coal

For the first time, renewable energy has surpassed coal as the primary source of electricity worldwide, according to a new report, marking a shift in global reliance on environmentally harmful fossil fuels.

Renewable energy contributed 34.3% of all global electricity generated in the first half of 2025, while coal fell to 33.1%. Renewable energies include sources like solar, wind, and hydro, as opposed to fossil fuels like coal and natural gas.

Nevertheless, global coal generation fell 0.6% in the first half compared to the same period a year earlier.

I think that most economies want to expand their clean electricity, but some are more strategic and seizing on the opportunity than others.

China has been particularly clever in decreasing its reliance on fossil fuels. Countries including Hungary, Pakistan and Australia set records in solar energy production, generating 20% or more of their electricity from solar power.

Global carbon dioxide emissions fell slightly in the first half of the year as solar and wind power "exceeded demand growth and led to a slight fall in fossil fuel use."

China has been the largest driver in the move to renewable energy sources, accounting for 55% of global solar generation growth. The United States' share, by contrast, was just 14%. Renewables might slow as the Trump administration moves to sharply reduce clean-energy development.

While the world — including the United States — is making significant gains in making energy cleaner, increased demand leaves renewables struggling to meet consumer needs. The tech race to integrate artificial intelligence into daily life is in part to blame.

This has really been an inflection point for the United States in that power demand in the U.S. had flatlined for a couple decades, and with the growth of data centers, and AI and crypto, and with other growth from industries and air conditioning, and so on, we're starting to see electricity demand grow 3% per year, rather than be flat or 1%.

Populous developing countries like China and India led the charge in adding more renewable energies. Meanwhile, Western societies including the European Union and the United States met some of their increased electricity demand through the use of fossil fuels during this period.

Plant This Shrub - Aronia

Aronia, or black chokeberry, fits well into permaculture landscapes due to its hardiness, ability to tolerate varied soil conditions, high antioxidant properties, and role as a native plant. It provides multi-season interest, self-fertile fruit production, and can be incorporated into edible landscaping, food forests, and systems like swales for its ecological function. While it produces astringent fruit, best suited for use in jams or smoothies, its resilience and contribution to a polyculture system make it a valuable permaculture species. 

Why Aronia is a Good Permaculture Plant

Nativism: 

Aronia is a North American native plant, integrating well into regional ecosystems. 

Toughness: 

It tolerates a wide range of soil types, including wet or clay soils, and can grow in full sun to partial shade. 

Food Production: 

It's a prolific producer of nutritious, high-antioxidant berries, though they are astringent when raw. 

Edible Landscaping: 

Its attractive foliage and fruit make it suitable for edible landscaping and food forest systems. 

Pest & Disease Resistant: 

The shrub is not often plagued by birds or pests and is generally free of disease. 

Integration into Permaculture Design

Polyculture Systems: 

Integrate aronia into a polyculture system with other native, edible, and beneficial plants for a more visually appealing and ecologically functional landscape. 

Food Forests: 

Place it in a food forest, potentially underplanting larger trees, to create edible layers within the system. 

Edible Swales: 

Consider planting aronia near or on swales to help manage water and provide ecological benefits while producing food. 

Care and Harvesting

Planting: 

Plant in spring or fall in a site with at least six hours of full sun for best fruiting. Amend the soil with compost and mulch to retain moisture and suppress weeds. 

Pruning: 

Prune after flowering to remove dead or diseased branches, but avoid heavy pruning after flowering to preserve berry production. 

Harvesting: Berries ripen in late summer and are best harvested when fully ripe, often after the first frost. They can be harvested with rakes or by snipping clusters, and are excellent when processed into jams, smoothies, or dried goods.
