Red phosphorus is a potential anode material for lithium-ion and sodium-ion batteries, but like sodium itself, its positive values are counter-balanced by considerable challenges. Academics in China and Poland have done a detailed systematic review of phosphorus anode research, which has been published for anyone to read. “The development of cost-effective and high-performance red phosphorus anode materials for Li-ion and ...

Custom lithium battery pack maker Alexander Battery Technologies has installed “the world’s most advanced laser welding machine”, it said, at its factory in Peterlee, UK. “The EV Flex laser welder uses machine vision and configurable optics to produce micrometer-accurate welds between the terminals on a battery cell and busbar,” according to the company. “Employing optical laser depth detection, the EV ...

Microsoft and the US Pacific Northwest National Laboratory (PNNL) have teamed up in a multi-year project to explore material science using AI and super-computing, and discovered a promising solid electrolyte for lithium-ion and sodium-ion batteries as a proof-of-concept. The multi-step process used to search for possible electrolytes reduced a list of 32 million inorganic materials to 18 in 80 hours, ...

The University of Birmingham has found a new reason why ball-milling, a technique over 100 years old, makes high-capacity Li-ion electrode materials. The use of ball milling has been a huge area of growth in the lithium-ion battery space, according to the university. It involves rotating precursors to the desired electrode material in a barrel along with hard heavy balls ...

Tokyo Institute of Technology has created a strategy to produce high ionic conductivity solid electrolytes for all-solid-state batteries with lithium metal electrodes. Such solid batteries could offer better battery safety – lithium metal (as opposed to lithium-ion) liquid electrolyte batteries have a poor safety record – but inferior ion conductivity is hampering their development. Inferior conductivity can be intrinsic to ...

Custom battery pack manufacturer Alexander Battery Technologies has opened an e-mobility battery engineering and production unit on its Peterlee campus in County Durham. “The Battery Technology Centre will add engineering and service capabilities as the company begins its first projects, developing and prototyping for e-mobility customers,” according to the company. “The 1,850m2 [20,000ft2] centre complements the company’s existing facilities in ...

Amprius Technologies of California is claiming energy density of 500Wh/kg and 1.3kWh/litre from its latest demonstration of lithium-ion battery technology. This is about double the capacity of today’s general purpose cells. “The energy density performance was verified by [test house] Mobile Power Solutions. The results indicate that this cell model provides >504Wh/kg and >1,321Wh/litre at 25°C,” according to Amprius. This ...

Varta has announced the next generation of its CoinPower flagship rechargeable lithium-ion cells range. “Cells of the A5 generation are suitable for TWS headphones and the current trend of gaming TWS Earbuds, wearables and IoT devices,” according to the company. “Customer project discussions are already taking place. The production of the new cells will start at the beginning of 2023.” ...

NGK Insulators, Ltd. (NGK) will exhibit at electronica 2022 at Hall B.430 under the theme of “Making smart society more comfortable by contributing to digital society with ceramic technology.” The company is expecting to discuss further collaboration opportunities with engineers and partners. NGK will show demonstrations of IoT device power supply, EnerCera® and unique ceramic technologies such as gallium nitride ...

Skoltech researchers have developed a novel material for lithium-ion batteries powering electric vehicles. The material is a familiar nickel-rich layered transition metal oxide, but with an altered microstructure that packs more energy per unit volume. “The cathodes in batteries powering electric cars tend to use layered transition metal oxides, including nickel-rich ones. We improved two commonly used materials of this kind, achieving a ...
