![]() Xin Li is an associate professor of materials science at School of Engineering and Applied Sciences (SEAS) at Harvard University, who was an assistant professor at SEAS from 2015 to 2019. ![]() A combination of electrochemical battery tests, SEM, XAS, XPS and XRD characterizations, and DFT simulations was used. On the cathode side, 5V all-solid-state batteries using layered LiCoO2 and spinel as cathodes will be presented and the stabilization mechanisms will be discussed. The decomposition pathway of LGPS at the anode interface is modified by this mechanical constriction and the growth of lithium dendrite is inhibited, leading to excellent rate and cycling performances. ![]() An advanced mechanical constriction technique is applied on all-solid-state batteries constructed with Li10GeP2S12 (LGPS) as the electrolyte and lithium metal as the anode. Experimental evidence and theoretical understanding of stability window expansion as the result of mechanical constriction will be discussed. Such swelling has been shown to provide viable means by which to stabilize electrochemical decomposition in lithium ion batteries. Adden Energy, Inc., a startup developing innovative solid-state battery systems for use in future electric vehicles (EVs) that would fully charge in minutes, announced the grant of an exclusive technology license by Harvard University’s Office of Technology Development (OTD) and a seed round financing of 5.15 million. Ceramic sulfides are known to substantially swell during electrochemical decay. The researchers paired the new design with a commercial high energy density cathode material. In this talk, methods for the stabilization of both the bulk electrochemical decompositions and the interfacial reactions will be discussed. Now, Li and his team have designed a stable, lithium-metal solid state battery that can be charged and discharged at least 10,000 times far more cycles than have been previously demonstrated at a high current density. In addition, ceramic sulfides are frequently plagued by interfacial reactions when combined with common electrode active materials. The ionic conductivities can meet or exceed liquid-electrolytes for such ceramic sulfides, however, there is a theoretical concern about the narrow electrochemical stability window of approximately 1.7-2.1 V vs lithium metal. Rinehart approves electrifying mine vehicle fleet.Ceramic sulfide solid-electrolytes are amongst the most promising materials for enabling solid-state lithium ion batteries. Mining giant accelerates automation after fewer accidents Mining giant approves electric driverless trucksĮmployer unveils zero emission electric truck An exclusive technology license has also been granted by the university’s office of technology development.Ī full scale vehicle-sized battery is expected to take three to five years to develop. Primavera Capital Group, Rhapsody Venture Partners and MassVentures have approved US$5.15 million (A$7.91M) in seed round financing. Our recent study shows that this nice feature can also be maintained at scale-up,” Adden chief technology officer Luhan Ye said. “As a result the device can sustain its high performance over a long lifetime. This is because the unit uses a “novel structural and material” design to defeat dendrite growth that penetrates and damages cathodes in conventional batteries.

Algorithms for Battery Management Systems: University of Colorado Boulder. The battery can be recharged up to 10,000 times throughout its lifespan, allowing the technology to be used for more than a decade before a replacement is required. In summary, here are 10 of our most popular battery courses. “EVs need to recharge at comparable times to internal combustion vehicles, essentially in the time you would currently spend at the gas pump.” “Complete electrification of the vehicle fleet is one of the most meaningful steps we can take to fight climate change,” Adden CEO William Fitzhugh said in a public statement. ![]() This is significantly faster than conventional recharging cycles that last between 10 and 24 hours. The research team, led by materials science associate professor Xin Li, confirmed the lithium-metal battery completely recharged in as little as three minutes – about the time it takes to refuel a diesel-powered light vehicle. Paulson School of Engineering and Applied Sciences. An energy storage company will begin mass producing an eco friendly alternative to at least one fossil fuel.Īdden Energy is preparing a commercially deploy solid-state battery systems for electric vehicles (EVs) that can be recharged up to 400 times faster than conventional units.Ī lab scale, coin-cell prototype has already been developed at Harvard University’s John A. Harvard University researchers have developed a solid-state lithium-metal battery that can be charged and discharged at least 10,000 times at a high current density marking a big leap. ![]()
