The new lithium battery electrolyte substantially increase the efficiency and service life

Image
US Department of Energy scientists at Pacific Northwest National Laboratory have developed a new type of electrolyte, lithium-ion batteries can not only solve the problem of short circuit fire, but also a substantial increase in battery performance and life. The researchers said the discovery could lead to the next generation of more powerful and practical rechargeable batteries, such as lithium sulfur and lithium-air and lithium metal batteries.

Super Capacitors and Super Capacitor Battery Technology Becoming Popular

When the industry agreed that the lithium-ion battery is still the main mode of electric vehicles energy reserves, some companies have already begun to consider the use of forward-looking ultracapacitor products as a lithium-ion battery is good supplementary equipment. Compared to conventional batteries, super capacitor can store electricity is not much, so the super capacitor and can not be used as a power supply device. Super capacitor has the ability to quickly release the stored energy, while the performance will not be completed in a short time to reduce the charge and repeatedly after charging. Recently, the South Korean electronics company claims will invest $ 9 million to expand its transportation, power systems and consumer electronics products with super capacitor capacity. In the United States, has the ability to design and manufacture products for the material and super capacitor electrolyte companies Graphene Energy, EnerG2 and Ioxus three. Another company from a ven

Mapping Mechanical Properties of Lithium/Polymer Battery Composites with Nanoindentation

Introduction The primary purpose of the work presented herein is to investigate the mechanical properties of a lithium rechargeable battery cathode 1-3 by utilizing both the classic XP CSM and newer, ultrafast DCM Express Test methods with a Nano Indenter G200 (Keysight Technologies) . Scanning electron microscopy analysis is used as a support to understand the obtained results and gain information about the differences between the two adopted nanoindentation methods. Particular attention is focused on the analysis of the mechanical and elastic properties of new-generation lithium/polymer electrodes, with the final aim of correlating the life cycle and the number of charge and discharge cycles with the mechanical properties of the electrodes. By employing an improved grid nanoindentation method 4-6 , it is possible to perform a statistical deconvolution of the mechanical properties and to understand how many (and which) heterogeneous material phases there are as well as how they i
