Amprius partners with US Army to develop silicon anode batteries for unmanned aircraft
Amprius Technologies has been awarded a contract with the US Army’s Rapid Capabilities and Critical Technologies Office. The 18-month rapid prototyping contract includes the design, development, and validation of high-energy-density silicon anode lithium-ion batteries to be used in unmanned aircraft system applications. Amprius offers a silicon anode battery with high energy density in commercially available… Read more »
Sila’s Drop-In Silicon Anode Technology for Li-ion Batteries
Advancements in the capabilities of lithium-ion batteries have slowed down in the last decade. As conventional electrode materials approach their theoretical limits, substantial gains in battery energy density only come as a trade-off in safety or performance. Kurt Kelty, Vice President of Commercialization for Sila will introduce an innovative drop-in-replacement nanocomposite, silicon-based anode powder that… Read more »
JAIST packs more juice into Li-ion batteries with silicon anodes and polymeric coatings
Although silicon anodes could greatly boost the capacity of Li-ion batteries, their performance rapidly degrades with use. Polymeric coatings can help solve this problem, but few studies have explored the underlying mechanisms. In a recent study, scientists from the Japan Advanced Institute of Science and Technology (JAIST) investigated how a poly(borosiloxane) (PBS) coating stabilizes the… Read more »
Silicon anode nanostructure could increase battery capacity and lifespan
Image caption: In the first stage, the silicon film exists as a rigid but wobbly columnar structure. In the second stage, the columns touch at the top, forming a vaulted structure, which is strong due to arch action. In the third stage, further deposition of silicon atoms results in a sponge-like structure. The red dashed… Read more »
Zenlabs says its silicon anode cells are ready for commercialization after 1,000-cycle testing
Idaho National Laboratory (INL) has successfully tested over 1,000 charge-discharge cycles using high-energy silicon anode pouch cells made by Zenlabs Energy. Zenlabs received a $4.8-million, 50% cost-share development contract from the United States Advanced Battery Consortium (USABC) to develop low-cost, fast-charge EV batteries. As a part of the USABC program, Zenlabs delivered its 12 Ah… Read more »
LeydenJar says its silicon anode boosts battery energy density by 70%
LeydenJar Technologies, a Dutch spinoff of the applied research institute TNO, has developed a new battery anode that’s made from 100% silicon. The company says this provides two key benefits: batteries with a 70% higher energy density (1,350 Wh/L) and 62% lower CO2 emissions than current models. The anode is ready for production, and LeydenJar… Read more »
Nexeon acquires 24 patents for silicon anodes
Silicon anode specialist Nexeon has acquired three sets of patents relating to the use of silicon in lithium-ion battery anodes. The 24 patents cover the manufacture and use of nano-scale silicon particles, alone or combined with graphite, as well as methods for coating carbon particles with silicon using vapor deposition. The patents have global coverage,… Read more »
Dutch startup LeydenJar to open pilot plant for Li-ion batteries with silicon anodes
Dutch startup LeydenJar is opening a pilot plant to manufacture new-generation batteries that utilize pure silicon anodes, which the company says can store 50% more energy than conventional lithium batteries. LeydenJar and its development partners hope to use the pilot plant to demonstrate that batteries with silicon anodes can be manufactured for the same price… Read more »
