Riding high on the crest of the e-mobility wave, Wevo-Chemie has worked with Germany’s electric surfboard manufacturer, Lampuga, to create polyurethane potting compounds which seal the boards’ lithium-ion batteries. The AIR 4 jet-powered surfboard has a 14hp motor and an exchangeable Li-ion battery with a capacity of up to 3.6kWh, allowing it to skim the water at up to 50kph. ...
Chalmers University of Technology in Sweden has revealed its third generation of structural lithium ion battery. “We have created a battery made of carbon fibre composite that is as stiff as aluminium and energy-dense enough to be used commercially, claimed Chalmers researcher Richa Chaudhary. First revealed with KTH Royal Institute of Technology in 2018, by 2021 the material was achieving 24Wh/kg, ...
Integrals Power has started production of its lithium-ion cathode materials in Milton Keynes, UK. “The pilot plant capable of producing 20 tonnes a year, demonstrating that the technology will scale to volume production,” according to the company, which has proprietary nano-material lithium iron phosphate (LFP) and lithium manganese iron phosphate (LMFP) intellectual property. “We believe this is one of the ...
Cambridge electric vehicle battery start-up Nyobolt has revealed a purpose-built testing and demonstration car, created with Callum Automotive of Warwick. “Whilst the priority use for this Nyobolt EV is showcasing and testing the battery technology, Callum’s team has engineered it so that low volume production, for road or track use, is possible,” according to Nyobolt. “Nyobolt’s battery assembly plans are ...
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 ...
