Water-in-salt electrolyte could enable high-voltage aqueous Li-ion chemistries
A team of researchers from the University of Maryland (UMD) and the US Army Research Laboratory (ARL) have devised what they call a “water-in-salt” electrolyte that could offer power, efficiency and longevity comparable to Li-ion batteries, but without the toxic chemicals and fire risk. In “Water-in-salt electrolyte enables high-voltage aqueous lithium-ion chemistries,” published in the… Read more »
Cambridge scientists claim promising lithium-oxygen battery advancements
Cambridge scientists have developed a working demonstrator of a lithium-oxygen battery that is more than 90% efficient, and can be recharged more than 2,000 times. Lithium-oxygen, or lithium-air, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of lithium-ion solutions. In “Cycling Li-O2 Batteries via LiOH Formation… Read more »
Solid-state battery innovator Seeo acquired by Bosch
Giant German automotive supplier Bosch has announced that it will acquire the Silicon Valley startup Seeo, a pioneer in solid-state battery technology. Seeo’s cell design combines a solid lithium metal anode with a conventional porous lithium iron phosphate cathode and Seeo’s proprietary DryLite solid polymer electrolyte. Seeo says its cells achieve specific energy of around… Read more »
Advanced Battery Consortium awards funds to Seeo to test solid polymer battery modules
The US Advanced Battery Consortium (USABC) has awarded a $299,000 contract to Seeo Inc. of Hayward, California. The nine-month technology assessment program will focus on testing of Seeo’s elevated-operating-temperature solid polymer battery modules. Under the contract, Seeo will deliver its DryLyte battery modules to USABC for testing and third-party validation. These modules are based on… Read more »
PolyPlus scores $9 million DOE grant for its battery technology
The PolyPlus lithium-water battery has achieved the highest energy density ever recorded – 1,300 Wh/kg, far more than the maximum delivered by current lithium-ion batteries.
