Researchers demonstrate Li-ion anode with silicon-nanolayer-embedded graphite/carbon
Larger figure Researchers from South Korea’s Ulsan National Institute of Science and Technology (UNIST) and Stanford University have demonstrated the feasibility of a hybrid anode for Li-ion batteries using silicon-nanolayer-embedded graphite/carbon. In “Scalable synthesis of silicon-nanolayer-embedded graphite for high-energy lithium-ion batteries,” published in Nature Energy, Minseong Ko and colleagues explain that this architecture allows compatibility… Read more »
Chinese researchers develop aluminum-graphite dual-ion battery
A team from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences has developed a novel, environmentally friendly low-cost battery. In “A Novel Aluminum-Graphite Dual-Ion Battery,” published in Advanced Energy Materials, Yongbing Tang and colleagues present a new aluminum-graphite dual-ion battery (AGDIB) that they say offers higher energy density than conventional LIBs, as… Read more »
Leclanché’s new Li-ion battery cell features Echion’s niobium-based anode material
Swiss energy storage provider Leclanché has developed a new Li-ion battery cell called XN50, which features Echion Technologies’ XNO, a niobium-based active anode material. “The cell provides integrators and OEMs with a differentiated battery option that outperforms existing chemistries in heavy-duty e-mobility, rail and marine applications,” says the company. Leclanché is set to replace its… Read more »
New findings could lead to more stable and safer lithium metal batteries
New research from Chalmers University of Technology shows why lithium metal batteries have short lifespans and how to extend them by creating the metal electrode directly in the battery cell. Lithium-ion batteries with metal electrodes instead of graphite electrodes are gaining attention. However, metal electrodes are reactive, making it hard to produce a long-lasting cell…. Read more »
