Cost remains one of the biggest hurdles to electric vehicle adoption. Most of today’s EVs sell for higher prices than fossil fuel-powered vehicles, and that’s keeping a lot of people from purchasing one. That might soon change. Coreshell, a battery materials startup, revealed a breakthrough this week that could lower the cost of lithium-ion batteries. […]

Research and industry worldwide work on the commercialization of perovskite photovoltaics. Most research laboratories focus on solvent-based manufacturing processes because these methods are versatile and easy to use. Established photovoltaic industries, however, almost exclusively apply vacuum processes for the deposition of high-quality thin films. An international consortium led by Karlsruhe Institute of Technology (KIT) and […]

The race is on to generate new technologies to ready the battery industry for the transition toward a future with more renewable energy. In this competitive landscape, it’s hard to say which companies and solutions will come out on top. Corporations and universities are rushing to develop new manufacturing processes to cut the cost and […]

A breakthrough could help lead to the development of new low-power semiconductors or quantum devices. As the integrated circuits that power our electronic devices get more powerful, they are also getting smaller. This trend of microelectronics has only accelerated in recent years as scientists try to fit increasingly more semiconducting components on a chip. Microelectronics […]

A new industrial-scale ‘sand battery’ has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant that’s been running since 2022. The sand battery, […]

There is a lot of mechanical energy in human activities, but human activities are low frequency and irregular. As such, traditional electromagnetic power generation mode cannot efficiently collect this energy without affecting the normal activities of the human body. A new energy harvesting method, called triboelectric nanogenerator (TENG), can efficiently collect low-frequency and irregular mechanical […]

“Big Three” automaker Chrysler will use lithium-sulfur batteries instead of the more traditional lithium-ion batteries in its new line of electric vehicles. Chrysler has contracted battery technology developer Lyten to provide the batteries. The California-based company opened its first automated lithium-sulfur battery production line in San Jose last year and recently told The Cool Down […]

Conventional lithium-ion batteries based on inorganic cathode materials containing transition metals (e.g., Co and Ni) are facing the ceiling of energy density and the concern of resource sustainability. Therefore, it is necessary to develop novel, highly efficient electrode materials, and rechargeable battery technologies without the limitation of resources. Organic electrode materials (OEMs), primarily comprised of […]

As NASA and Boeing enter the early stages of producing the X-66, the first X-plane specifically focused on helping the United States achieve net-zero aviation emissions by 2050, the team is already picturing what the aircraft will look like soaring above the clouds. A new rendering of the X-66 from Boeing demonstrates the aircraft’s signature […]

Rivian surprised everyone today by not only revealing the hotly-anticipated R2 SUV at a starting price of just $45,000, but also showing us another car, the R3, as well as a new battery cell that underpins both cars. The cell is called the 4695 due to its diameter of 46 millimeters and height of 95 […]
