3+ hour, 18+ min ago  (207+ words) Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla's batteries. If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant alternative…...

1+ day, 3+ hour ago  (207+ words) The global cobalt supply chain is more interconnected'and more vulnerable'than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries. Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn…...

1+ week, 3+ day ago  (247+ words) At the heart of these systems is an electrolyzer, which converts electricity from solar cells into chemical energy. That energy is then stored in the form of fuels such as formic acid. However, conventional MPPT setups typically depend on batteries…...

4+ week, 1+ day ago  (724+ words) Demand for lithium is soaring as automakers ramp up electric vehicle production and energy companies build larger battery systems to support wind and solar power. But producing lithium remains a slow and environmentally costly process. Current extraction methods work best…...

1+ mon, 3+ day ago  (611+ words) Scientists have developed a surprising new way to power materials that normally cannot conduct electricity, opening the door to a new generation of ultra pure near infrared LEDs for medical imaging, communications technology, and advanced sensors. The breakthrough relies on…...

1+ mon, 6+ day ago  (207+ words) Scientists at UC Santa Barbara have created a remarkable new material that works like a "rechargeable solar battery," storing sunlight inside tiny molecules and releasing it later as heat " even long after the sun goes down. Inspired by reversible changes…...

4+ mon, 2+ day ago  (298+ words) A team at the University of Oxford has created an advanced technique that makes it possible to clearly see a vital component inside lithium-ion battery electrodes that scientists have struggled to track. The findings, published on February 17 in Nature Communications,…...

10+ mon, 3+ week ago  (386+ words) One of the key determinants to the lifespan of a battery - aqueous or otherwise - is the anode. Chemical reactions at the anode generate and store the battery's energy. However, parasitic chemical reactions degrade the anode, compromising the battery lifespan. The…...

5+ mon, 3+ week ago  (704+ words) The United States may already be producing most of the critical minerals it needs, but much of that material is currently going unused. A new statistical study led by Elizabeth Holley and her research team shows that valuable minerals could…...

11+ mon, 1+ week ago  (234+ words) Scientists in China have developed a precise method to grow titanium dioxide nanorod arrays with controllable spacing, independent of rod size. This innovation boosts solar cell efficiency by allowing light capture and charge movement to be fine-tuned. New Nanotech Boosts…...
