Researchers make Ceramic-based flexible electrolyte sheets for lithium metal batteries
Researchers at Tokyo Metropolitan University have developed a new method to make ceramic-based flexible electrolyte sheets for lithium metal batteries. They combined a garnet-type ceramic, a polymer binder, and an ionic liquid, producing a quasi-solid-state sheet electrolyte. The synthesis is carried out at room temperature, requiring significantly less energy than existing high-temperature (>1,000° C) processes…. Read more »
Researchers track lithium ions in a fast-charging battery
A team of scientists led by the DOE’s Brookhaven National Laboratory and Lawrence Berkeley National Laboratory has captured in real time how lithium ions move in lithium titanate (LTO), a fast-charging battery electrode material made of lithium, titanium and oxygen. They discovered that distorted arrangements of lithium and surrounding atoms in LTO “intermediates” (structures of… Read more »
Enevate says its silicon-dominant anode technology is ready for EV production
Q&A with Enevate’s Founder and CTO Dr. Benjamin Park Introducing silicon into automotive-grade lithium-ion cells has been a major topic in the EV industry in the past decade. Silicon is widely considered to be the next big thing in anode technology, because it has a theoretical charge capacity ten times higher than that of typical graphite anodes…. Read more »
Enevate says its new silicon-dominant battery tech enables 5-minute charge
Enevate, a battery technology company based in Irvine, California, has launched its fourth-generation XFC-Energy battery technology, which offers 800 Wh/L cell energy density and achieves five-minute charging to 75 percent capacity, according to the company. The XFC-Energy technology is designed for large-format pouch, prismatic, and cylindrical EV cells. It uses pure silicon anode technology with… Read more »
