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 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 »
Sponsored by Arkema The lithium-ion battery market is demanding higher energy density, extended lifetime, and improved power performance. Arkema’s Battery Solutions address many of these demands. Advances in electrode materials are addressing energy density, while new electrolyte systems can significantly improve lifetime and power performance. LiFSI, in particular, is a good candidate to replace LiPF6,… Read more »
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 »
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 »
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 »
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 »
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 »
With a fresh round of funding, Wildcat Discovery Technologies is busy expanding its facilities, building up its battery team and doubling down on promising solid-state research projects. We asked the energy storage experts to help clear up the hype around solid-state batteries. Whenever Charged needs to better understand the complexities of the latest and greatest battery… Read more »
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 »
