Reports Of Fossil Fuels’ Death Are Greatly Exaggerated

Great efforts are underway to decarbonize the global economy. It’s not just that Western political leaders pledge commitments to net-zero emissions by 2050 or shortly thereafter. Corporations are also investing in a green-energy future as if a carbon-free world is…

Battery Parts Can Be Recycled Without Crushing or Melting, Saving Valuable Raw Materials

Researchers in Finland have discovered that electrodes in lithium batteries containing cobalt can be reused following a special process. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process—which newly saturates the electrodes with lithium—saves valuable raw materials, and likely also energy. The rechargeable batteries […]

Microorganisms on the Rio Grande Rise are a basis for life and a possible origin of metals

(Fundação de Amparo à Pesquisa do Estado de São Paulo) Researchers conducted the first large-scale survey of the microbiota present in the seamount’s ferromanganese crusts, describing bacteria and archaea involved in the nutrient cycle and formation of metals. Brazil has mineral exploration rights to the Rise, but mining there will have a major environmental impact.

A lightweight and durable radiator for cooling electric vehicle batteries

(Peter the Great Saint-Petersburg Polytechnic University) Researchers from Peter the Great St. Petersburg Polytechnic University (SPbPU) invented a durable and compact radiator for lithium-ion batteries, which in the future can be used for electric vehicles. The radiator was developed using friction stir welding technology.

Charged up: revolutionizing rechargeable sodium-ion batteries with ‘doped’ carbon anodes

(National Korea Maritime and Ocean University) Rechargeable batteries like lithium-ion batteries (LIBs) are seeing a surge in demand as technologies like electric propulsion ships and other vehicles become increasingly popular. However, lithium is costly, which has driven the search for other options. Sodium-ion batteries (SIBs) are a more sustainable alternative but are thermodynamically unstable with graphite–the usual anode material. Now, researchers in Korea have developed a “heteroatom-doped” (modified) carbon-based anode that helps SIBs to surpass the performance of LIBs.

The Importance of Battery Recycling For Our Future

What do you do when your batteries are dead? How do you get rid of rechargeable electronics when they no longer hold a charge? Battery recycling is mandated in many areas, but consumers don’t always understand the process. If your hauler tells you not to put batteries in your recycling bin, you probably think they […]

New NiMH batteries perform better when made from recycled old NiMH batteries

(Stockholm University) A new method for recycling old batteries can provide better performing and cheaper rechargeable hydride batteries (NiMH) as shown in a new study by researchers at Stockholm University.

MRI scanning assists with next generation battery design

(University of Birmingham) Magnetic resonance imaging (MRI) can provide an effective way of supporting the development of the next generation of high-performance rechargeable batteries, according to research led by the University of Birmingham.

Scientists develop high-performance lithium-sulfur batteries

(Chinese Academy of Sciences Headquarters) Recently, research groups led by Prof. LIU Jian and Prof. WU Zhongshuai from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have developed Fe1-xS-decorated mesoporous carbon spheres as the nanoreactor, which can be applied as lithium-sulfur battery cathode.

Potassium-driven rechargeable batteries: An effort towards a more sustainable environment

(Tokyo University of Science) Concerns about the scarcity of lithium and other materials necessary in the now-ubiquitous lithium-ion batteries have recently driven many researchers to look for alternatives, such as sodium and potassium. Prof Shinichi Komaba from Tokyo University of Science, Japan, and his team have worked for over a decade on this topic. In his latest review article, he extensively discusses his findings on the recent advances, promises, and limitations of potassium-ion batteries.
