High C-Rate Discharge in Portable Electronics, and its Effect On Cycle Life and Runtime
Brian Fritz, Power Source Engineer, Intel
Battery runtime in portable devices continues to be a primary issue for most consumers. The push for smaller and lighter systems, along with processors that operate at high performance levels for short periods of time, has led to an increase in the peak C rates seen by batteries in portables. An examination of the peak currents and timeframes for those currents in next generation devices is discussed. The effect on cycle life of a variety of cells is presented. The challenge of decreasing cell counts, voltage headroom needed for DC/DC conversion, and the impact this has on runtime and performance is discussed.
Development of Ultrathin Ultracapacitors for Portable Electronic Applications
Dr. Edward Buiel, Coulometrics, LLC
The direction of consumer electronics products such as smart phones and laptop computers favors smaller and thinner devices with greater energy and power densities. Future battery technologies offering higher energy density, such as those based on silicon anodes, or mg-ion, will do so at the expense of power density at least initially. The use of thin supercapacitors connected directly in parallel with next generation batteries may provide higher energy and power densities compared to conventional lithium-ion batteries in certain applications. One such application is the GSM (Global System for Mobile Communication) and in particular, LTE (Long Term Evolution). These communication protocols are low duty cycle and have high power requirements that is particularly well suited for a hybrid battery-supercapacitor energy storage device.

Choosing the Right Lithium Ion Cell for Your Battery Pack
Carl Gallenson, VP of Engineering, iTECH
Designers of portable equipment face many decision points during the development cycle. Ensuring the rechargeable battery pack is well matched to the host equipment is often overlooked or not given sufficient priority until performance and/or supply problems occur. Proper cell selection is key and requires much more than checking dimensions and capacity. Designers need to consider loading, environment, shelf life, and a number of other factors specific to the application. This presentation will provide a systematic approach to cell selection to ensure that the pack is well matched to the application demands as well as providing several specific case examples.
Can Battery Life Modeling Really Aid in Mapping/Optimizing Usage Profiles and Pack Design?
Kevin L. Gering, PhD, Technical Program Manager, Diagnostic Testing and Applied Battery Research, Idaho National Lab
Electrochemical cells are essentially batch reactors that can undergo reactivity of their components in response to a number of environmental and operational conditions. Long-term stability and resilience of these heterogeneous chemical systems is guided by principles involving thermodynamic equilibrium and system compatibility between chemical and physical/mechanical regimes. Fundamental understanding of the relationship between aging conditions (stress factors) and aging mechanisms is key for producing robust prognostic modeling tools that can facilitate optimizing complex usage profiles over extended time to prolong battery life, as well as predict the impact of disparate aging among cells within a given string configuration. Modeling results for such targets will be demonstrated.
High Specific Lithium Cells for Security, Military and Aerospace Applications

In this framework new chemistries for higher energy density Li-ion cells, above 250 Wh/kg, their assembly in a 70 Wh battery pack with 60 percent autonomy increase compared to commercial competitor at equivalent weight and further developments for larger Li-ion cells capacity (40 Ah) reaching 300 Wh/kg will be shown at prototypes level.
Electrodeposition as a Synthetic Route Toward 3D Lithium-Ion Batteries with
Derek C Johnson, Ph.D., Director of Engineering and Technology Development, Prieto Battery, Inc.
Lithium-ion batteries are being sought after for high power applications with long cycle life. To meet the performance requirements, the shortcomings that have relegated the use of conventional Li-ion batteries to low-power applications need to be addressed. The use of a three-dimensional architecture with interdigitated electrodes has been proposed to alleviate the shortcomings because it allows a significant decoupling of energy and power density. A new approach is to fabricate a 3D solid-state Li-ion cell using electrodeposition as the main synthetic technique. Characterization and performance of the individual components as well as the composite 3D structure will be presented.

Analytical Methods for Characterizing Battery Materials
Sanjay Patel, Ph.D, Director of Analytical Services, Evans Analytical Group
Advanced batteries used in mobile devices require good performance at low cost and meet safety requirements. While the industry works to improve batteries used in these devices, there are many challenges with analyzing the complex electrode materials that are inside every battery. Electrochemical processes that occur during battery charge/discharge cycles need to be understood in order identify unwanted side reactions that cause degradation in battery performance. In addition, good battery reliability and safety requires consistency in material quality at every manufacturing step. In this presentation, we show how selecting the appropriate analytical technique results in improvements in R&D and better control of material quality during manufacture. We will present data on a study where we analyze a range of electrode materials prior to battery manufacture and show how impurity levels affect battery performance.
Extended Producer Responsibility: The EU Battery Directive Goes Global
Ofira Varga, Senior Consultant, 1WEEE Services GmbH
After almost seven years of the Battery Directive, producers of batteries and electronic products containing batteries face an increased number of battery take back and recycling legislations worldwide. More and more markets such as Brazil, Canada, Japan and Israel are implementing regulatory frameworks which, in some cases reflect the rules established by the European Battery Directive in others the national rules on waste batteries are based on a different approach. With this in mind, global acting companies are constantly facing new or wider producer responsibilities with respect to waste batteries. The presentation will provide an overview on the principle of producer responsibility of waste batteries, it will summarize the key obligations of producers of batteries and electronic products containing batteries and will outline regulatory differences such as the scope and financing and take back obligations in selected jurisdictions.

Thermal Protection for Lithium Cells in Ultra-Thin Portable Electronics
Barry Brents, Application Engineer, TE Circuit Protection
Designers are turning to high-capacity LiP (Lithium Polymer) cells to optimize space in media tablets, ultra-thin PCs and other slim electronic devices. At the same time, battery suppliers have been challenged to find ultra-compact overtemperature protection devices that are compatible with the higher discharge currents typically found in these applications. In response to these new technology requirements, TE Circuit Protection has developed the MHP-TA (Thermally Activated) series of ultra-low-profile resettable thermal cut-off (TCO) devices for lithium battery protection. The presentation will cover the key end-market and battery market trends driving the need for this new circuit protection technology. It will provide an overview of the MHP-TA technology concept, device design, an application example and technical advantages.

Christopher Lang, Group Leader, Energy Technologies, Physical Sciences, Inc.
Higher performance, safer secondary batteries are necessary to meet the demands of current and future electronic devices. Increasing energy densities of batteries tighten the required tolerances and the potential for catastrophic system failure. Recent research efforts have been successful in developing novel coating techniques that significantly improve the abuse tolerance of cells. This presentation will summarize these efforts and highlight the performance benefits these technologies offer.
Understanding Battery Behavior in Multi-Cell Configurations
Bor Yann Liaw, Hawaii Natural Energy Institute
Portable power electronic applications require reliable and safe operation of battery packs. The operation of such battery systems in portable devices is inevitably becoming more complicated. To meet the power and energy demands in these applications, multi-cell configurations are often required for the applications. The safety and reliability of these battery systems hinges on better understanding of the battery performance in the multi-cell configurations. Here we discuss the study of three-cell strings to derive useful information regarding the performance and aging behavior of the cells in the strings. With vigorous data analysis using techniques such as incremental capacity analysis as functions of battery selection and SOC, we found that the SOC and SOH of multi-cell strings can be determined by the rationalization of battery behavior. The process explains how the limiting cell is identified and how such cell affects performance in the multi-cell configurations.
Nanofiber/Microfiber Lithium Ion Battery Separators
Dr. Brian Morin, CEO, Dreamweaver International, Inc.
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow. In this work, linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60 percent) and much higher ionic flow. Batteries made with these separators are able to give similar performance at much higher electrode coat weights, reducing the surface area of both current collectors and separator and also the volume of electrolyte needed. Applications include all power source applications that require high energy density, high power, high temperature stability, including cell phones, laptop and tablet computers, power tools, and electric and hybrid vehicles.

Cutting the Cord: Choosing a Battery Architecture to Satisfy Product & Safety Requirements
Ryan Striker, Senior Electrical Engineer, Logic PD
In markets ranging from industrial to military to consumer and medical, user expectations have been raised by the smart phone. Application-specific devices are now expected to have a touchscreen and be portable, compact and lightweight. The aims to be portable and compact often find themselves at odds. Products could be smaller if on-demand power were delivered through a power cord. But portable devices must cut the cord, and so batteries are implied. Experience has shown multiple ways to safely and efficiently integrate batteries into an overall system design. Different products value different parameters and different approaches are appropriate to each. The chosen architectures for recent medical and consumer devices will be presented and discussed.
Battery Management in High Power, Compact and Low Cost Applications via Impedance Spectra-Based Dynamic Voltage Correlation
Yandong Zhang, Algorithm Engineer, Texas Instruments
Discover the dynamic voltage correlation (DVC) technology that enables accurate capacity gauging without a sense resistor. In DVC technology, we treated the battery itself as a sensor resistor and the current and the passed coulomb are estimated from the measured voltage by using the voltage-current correlation. Then other batteries states (OCV, SOC, FCC) are obtained based on the estimated current (and passed coulomb). For characterization of batteries’ voltage-current correlation, we developed a comprehensive battery impedance model so that batteries’ fast, middle and slow dynamic processes are all covered. The battery impedance model includes several hundred parameters and these parameters can be automatically generated after a set of standard tests.

From Processor to Power: The Copernican Moment for
Sam Jaffe, Senior Research Analyst – Energy, Pike Research
For the last three decades, portable device designers focused their decisions around the processor. It determined size and specifications of everything else in the device. That is now undergoing a transformation: the power supply (battery, BMS and charging controller) is now the central design decision of any portable device. A better battery has more of a sales impact than any increase in speed of the processor. This presentation will focus on how batteries will impact the portable power market in the coming years. New market research models by Pike Research will be revealed, including the overall market size and ten year forecast for batteries for the consumer electronics, portable power tool and other markets (non-traction automotive, mining, defense, etc.) The talk will also explore the place of emerging battery technologies (new lithium ion formulations and beyond Li-Ion concepts) in this new battery-centric universe.
