New SES Li-metal battery reaches 107 Ah

Battery supplier SES has released Apollo, a 107 Ah Li-metal battery for EVs. The company also announced plans for its Shanghai Giga plant, a 300,000-square-foot facility that the company hopes will be capable of producing 1 GWh of batteries annually by 2023. SES has addressed the dendrite safety problem associated with Li-metal batteries by coating… Read more »

SK becomes third-largest shareholder of battery company SES

SK has invested an additional $35.9 million in SES (formerly SolidEnergy Systems), a developer of lithium-metal batteries. Coupled with its original $26.7 million investment in 2018, SK now becomes the third-largest shareholder of the battery company. SES, which launched in 2012 as an MIT research lab startup, is headquartered in Singapore, and operates labs and… Read more »

Factorial Energy unveils 40 Ah solid-state EV battery cell

Factorial Energy has introduced what it says is the first 40 Ah solid-state EV battery cell.  The Factorial Electrolyte System Technology (FEST) is a proprietary solid electrolyte material designed to enable safe and reliable cell performance with high-voltage and high-energy-density electrodes. Solid electrolytes like FEST are considered safer than conventional lithium-ion technology, as they replace… Read more »

Wildcat ramps up its focus on EV Supercell breakthroughs

The lithium-ion battery has proven to be an excellent fuel tank for EVs, but there remains much room for improvement. We’re still far from what’s theoretically achievable in terms of Li-ion capacity, safety, cost and charge times. As battery manufacturers continue their quest for improved chemistry and material combinations, they rely on applied researchers like… Read more »

MIT researchers use semisolid electrode to prevent short circuits in lithium metal batteries

Researchers may have found ways to prevent dendrite formation in solid-state batteries. Their findings are described in the journal Nature Energy, in a paper by MIT graduate student Richard Park, MIT Professor Yet-Ming Chiang and researchers at MIT and other institutions. Chiang explained, “The only way you can reach the energy densities that are interesting… Read more »

Oxis Energy’s ultralight Li-sulfur batteries are aimed at aviation

Oxfordshire-based Oxis Energy has been working on lithium-sulfur battery technology since 2004 (Charged has reported on the company several times over the years). In a recent article in  IEEE Spectrum, the company’s Head of Battery Development and Integration, Mark Crittenden, explains why lithium-sulfur tech is uniquely suited to electric aviation. Weight is a critical constraint… Read more »

Researchers develop novel battery electrolyte for lithium metal batteries

A new lithium-based electrolyte invented by Stanford University scientists could pave the way for the next generation of EVs. In a study published in Nature Energy, Stanford researchers demonstrated how their novel electrolyte design boosts the performance of lithium metal batteries. “Most electric cars run on lithium-ion batteries, which are rapidly approaching their theoretical limit… Read more »

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 »
