Batteries 2018 Annual Progress Report

This document summarizes the progress of VTO battery R&D projects supported during the fiscal year 2018 (FY 2018). In FY 2018, the DOE VTO battery R&D funding was approximately $101 million. Its R&D focus was on the development of high-energy batteries for PEVs and very high-power devices for hybrid vehicles. The electrochemical energy storage roadmap describes ongoing and planned efforts to develop electrochemical storage technologies for PEVs. To advance battery technology to improve the market penetration of PEVs and hybrid vehicles, the program focuses on overcoming specific technical barriers typically related to the battery’s cost, performance, life (both calendar life and cycle life), its tolerance to abusive conditions, and its recyclability/sustainability. Various battery chemistries are being investigated with that aim.

Perspectives of automotive battery R&D in China, Germany, Japan, and the USA

Lithium(-ion) batteries are and will be the battery technology of choice for a wide range of applications - including electric vehicles - for several years to come. Nonetheless, to foster the transition from combustion engine vehicles to a fully electrified transportation, further progress is needed. In this regard, the annual International Conference on Advanced Lithium Batteries for Automobile Applications (ABAA) targets the intensive exchange of the involved industrial and research entities to jointly ensure the further progress of this technology. During the past meeting, ABAA-10, held in October 2017 in Chicago, IL, USA, representatives of China, Germany, Japan, and the USA provided a comprehensive overview of the current and future battery R&D activities in their countries, depicting a highly insightful survey about partially concurrent, partially complementary research and funding strategies. Here, the given presentations are provided in the Supplementary Material for this Special Perspective, while this perspective paper may serve as brief introduction to the general development in the field concerning the overall EV sales and common considerations regarding future material developments.

Program For Generating Interactive Displays

Sun/Unix version of Transportable Applications Environment Plus (TAE+) computer program provides integrated, portable software environment for developing and running interactive window, text, and graphical-object-based application software systems. Enables programmer or nonprogrammer to construct easily custom software interface between user and application program and to move resulting interface program and its application program to different computers. Plus viewed as productivity tool for application developers and application end users, who benefit from resultant consistent and well-designed user interface sheltering them from intricacies of computer. Available in form suitable for following six different groups of computers: DEC VAX station and other VMS VAX computers, Macintosh II computers running AUX, Apollo Domain Series 3000, DEC VAX and reduced-instruction-set-computer workstations running Ultrix, Sun 3- and 4-series workstations running Sun OS and IBM RT/PC and PS/2 compute

Data storage systems technology for the Space Station era

The paper presents the results of an internal NASA study to determine if economically feasible data storage solutions are likely to be available to support the ground data transport segment of the Space Station mission. An internal NASA effort to prototype a portion of the required ground data processing system is outlined. It is concluded that the requirements for all ground data storage functions can be met with commercial disk and tape drives assuming conservative technology improvements and that, to meet Space Station data rates with commercial technology, the data will have to be distributed over multiple devices operating in parallel and in a sustained maximum throughput mode.
