Advances in Solid State Batteries
Speaker: Kevin S. Jones, Professor MSE, University of Florida, Co-Director, Software & Analysis of Advanced Materials Processing Center and Collaborator with Planar Energy
The intense focus on renewable energy and the increasing interest in developing electric drive vehicles (EDVs) has generated renewed interest in solving many energy storage challenges. Currently, Li ion battery (LIB) technology provides the highest energy density and specific energy of any rechargeable battery chemistry with an annual market of $5-6B that is projected to exceed $20B within the next 10 years. The vast majority of state-of-the-art LIBs utilize liquid electrolytes. However, because of the challenges of safety, cycle life and capacity, all of which are particularly important considerations in EDV applications, there is substantial interest in developing alternatives including an all solid-state LIB technology. In the early 1990s, the solid-state battery market started to grow rapidly after the discovery of Li-P-O-N solid-state electrolytes, which exhibit high Li ion conductivities. Several small thin-film solid-state battery companies grew out of the discovery of LIPON; these companies relied upon traditional vacuum-based deposition processes for battery fabrication, which limited the thicknesses of the films and added significantly to the capital equipment cost. Additionally, as the thickness of the anode and cathode are increased to enable higher capacity batteries the inherent strain at solid-solid interfaces upon cycling can compromise interface integrity and reduce cell performance. Therefore, these factors have, to date, limited commercial penetration of solid-state batteries to micro- and Li polymer batteries where the performance requirements justify the higher manufacturing costs. The solid-state battery market is currently around $50M or 1% of the total LIB market. Therefore, without changes in the cost of manufacturing or the materials used, it is difficult to envision the solid-state battery market exceeding $500M. Recently, a new method of inexpensive, non-vacuum electroless deposition has been developed by Planar Energy to fabricate solid-state batteries using a roll to roll approach. This process has been combined with a new solid thio-LISICON electrolyte and novel approaches to the cathode and anode to produce solid state batteries with greatly increased capacity. These recent developments offer the potential development of low-cost solid-state LIBs for use in EDVs. Here, a review of solid-state LIB technology is presented from the first viable micro-batteries to the current technology being developed for use in EDV and future applications.
9:30 to 10:25 a.m.
Ceramic Components for Fuel Cells and Other Energy Applications
Speaker: John Olenick, CEO & President, ENrG, Inc.
Since 1960, the planet has changed due to increasing levels of carbon dioxide in the atmosphere. Similar increases over the next 50 years will reach a level beyond that which is comfortable for all species. At the same time, the global demand for energy, water and food will soar. Today’s commercialization efforts of fuel cell technology and other advanced energy methods can be an important piece of the overall solution to provide more clean energy. Ceramic components are becoming increasingly important in the Cleantech market space providing means for ion transport, thermal management, catalysis of gases and liquids, power generation, energy storage, hydrogen purification and storage generation of light, and energy from waste processes.
10:45 to 11:40 a.m.
The Market Outlook for Energy-Related Technologies
Speaker: Kevin See, Analyst, Lux Research
Emerging markets provide great opportunity for materials suppliers and researchers, as they spur the growth of new supply chains for novel applications. Here we review the drivers creating opportunities for ceramic materials in several areas, including electric vehicles, advanced coatings and composites, and water treatment. In order to sort through the hype surrounding these markets, we will examine trends in each of these areas and discuss the economic, regulatory, and technical factors that affect adoption now and in the future.
1:00 to 1:55 p.m.
Small Modular Nuclear Reactors
Speaker: Terry Michalske, Lab Director, Savannah River National Laboratory
Michalske will discuss new developments in small modular reactors (SMR). The SMR concept is changing paradigms in nuclear power by providing small, grid-appropriate reactors with enhanced features, including passive safety controls. Additionally, SMRs are generally shop-fabricated; greatly reducing capital costs and opening new opportunities to the manufacturing sector, including materials manufacturing. Michalske will discuss these opportunities and provide an overview of recent SMR development.
2:00 to 2:55 p.m.
Material Needs in Alternative & Renewable Energy for the Automotive Industry
Speaker: Mark Verbrugge, Director, Chemical Sciences and Materials Systems Lab, GM Research & Development Center
The first portion of the lecture will relate global energy challenges, trends in personal transportation, and electrochemical energy storage technologies. Great progress has been made in recent years relative to battery technology. Primary concerns associated with lithium ion batteries and high-volume traction applications are associated with cost, life (cycle and calendar), and performance over a wide temperature range. Despite these concerns, it is well recognized that soon lithium ion batteries will be used in a variety of electrified vehicles, spanning from engine start/stop applications to hybrid electric vehicles to pure electric vehicles. Hence, it is critically important to understand phenomena governing the durability of lithium ion cells within the context of traction applications and to indentify improved electrode materials. We focus the technical part of this talk on (1) the combined mechanical and chemical degradation of lithium ion electrode materials, including both recent theoretical and experimental methods to clarify the governing phenomena and (2) new materials offering promising for high energy and high power applications.
