Published Stabilizing lithium-ion batteries with microbially synthesized electrolyte additive
(via sciencedaily.com) Lithium-ion batteries with high-energy-density cathodes are necessary to meet the energy demands of next-generation electronics and electric vehicles. At high voltages, however, the battery electrolyte undergoes excessive decomposition, compromising cathode performance. To tackle this, researchers have now synthesized a bio-based, non-toxic additive material that stabilizes the cathode by forming a passivation layer on its surface and suppressing its decomposition. Eco-friendly and low-cost, the novel compound could promote a wider utilization of bio-based resources.
Published Nanoengineers develop a predictive database for materials
(via sciencedaily.com) Nanoengineers have developed an AI algorithm that predicts the structure and dynamic properties of any material -- whether existing or new -- almost instantaneously.
