Study of Polarization Effect and Thermal Stability in Aged Lithium-Ion Battery
Battery Safety 2012 December 6-7, 2012, Las Vegas, NV, USA
Advancements in System Design, Integration & Testing for Safety & Reliability
"Study of Polarization Effect and Thermal Stability in Aged Lithium-Ion Battery"- By Mahmood Tabaddor, PhD, Underwriters Laboratories
Research into the safety performance of lithium-ion cells has increased tremendously in recent years.
Field failures, though rare, may suggest that some failure mechanisms are dependent upon the state of the cell over a period of time, as such rechargeable sources of energy experience many charging and discharging cycles.
UL has hence proposed a project to investigate the safety performance in aged lithium-ion cells.
After a series of study, the polarization effect and the shift in the thermal properties in aged cells are found to be the major causes to safety concerns. >> More

Large Capacity L-ion Battery Technologies and Market Prospects
A book, entitled “Large Capacity L-ion Battery Technologies and Market Prospects”, has been recently published.
The major points discussed in the book are the following two.
1) The material technology and the battery technology are both described.
2) Market prospects of L-ion batteries for medium- and large-scale applications, including electric cars.
The lithium resource is plentiful in amount. Lithium is dangerous due to its nature of corrosive and explosive, however. It is an urgent desire to improve the technology to extract lithium from seawater containing an infinite amount of lithium particularly in Japan. The all-solid-state L-ion battery, which copes with the explosive, has been developed to a significant level. Further, the current social circumstance demanding use of clean energy requires acceleration of the research and development of the L-ion battery which stores and discharges electrical energy.
The L-ion battery is expanding its market to the market of medium- to large-scale L-ion batteries for automotive and industrial applications.
Vigorous efforts are focused on development of elemental technologies of L-ion battery such as electrodes and electrolyte, and materials used for them. >> More

"Characterizing Crash Safety of Cylindrical and Pouch Li-ion Batteries using Computational Modeling"
Battery Safety 2012 – December 6 – 7, LasVegas, NV
- Advancements in System Design, Integration & Testing for Safety & Reliability
"Characterizing Crash Safety of Cylindrical and Pouch Li-ion Batteries using Computational Modeling"- By Elham Sahraei, PhD and Tomasz Wierzbicki, PhD, Massachusetts Institute of Technology
Mechanical integrity of Lithium-ion batteries is one of the most important issues on safety of electric cars, but the least studied topic.
As these batteries are not limited to stationary applications anymore, and are being used in vehicle battery packs, this aspect of their safety is more urgent to be characterized and quantified.
The automotive industry has realized that no battery pack could be rigid enough to ensure zero deformation to battery pack in severe enough crash conditions.
In this research, two common form factors of cylindrical and pouch batteries are characterized for several scenarios of deformation applied to these cells.
A comprehensive testing program was used to characterize the material properties of the cells under combined tension and predominantly compression and shear loading.
Then, computational models of the cells were developed.
The models successfully predict load-deformation trajectory and kinematics of the cell under various types of tests.
Additionally, the models are capable of predicting failure in the jelly-roll of the cell, indicating an internal short-circuit under mechanical deformation.
To compare the pouch and cylindrical cells tested in this research, the cylindrical cell tolerated a load of 5,500N and a deformation of about 7 mm before reaching short circuit,
while the pouch cell tolerated a load of 7,500N and a deformation of 3 mm before failure.
Predicting onset of electric short circuit is a necessary condition for possible thermal runaway.

Small fuel cells, some examples in Japan
The DMFC (direct methanol fuel cell) is a typical example of the small fuel cell. Some types of the DMFC have been commercially available worldwide. The volume and energy density of the fuel cell are both much higher than of other battery cells.
The small fuel cells will be used as the power sources in places where no power infrastructure is installed and the power infrastructure installed does not reach, and emergency power sources in disaster cases. Particularly in Japan, much interest has been placed on how to secure electric power sources in emergency situations after the 3.11 earthquake/tsunami disaster and the Fukushima nuclear meltdown. There is a strong demand for the small fuel cells in the market. >> More

Hitachi’s DMFC, advancing toward the next step
Hitachi has revealed two DMFC technologies recently.
One of them concerns improvements of the high polymer electrolytic membrane. The result is that the methanol penetration of the electrolytic membrane is reduced half and the DMFC power generation efficiency is improved 5%.
The other concerns catalyst technologies to be applied to the fuel and air electrodes of the DMFC. Those catalyst technologies are free from platinum. The result is that the DMFC incorporating the technologies is reduced by 45% when compared with those using platinum.
Hitachi and CPI (The Centre for Process Innovation Ltd.) have signed an agreement to industrialize the DMFC in England. In the agreement, Hitachi will develop the DMFC and CPI will carry out the demonstration test of the developed DMFC. Hitachi has a long history to develop the DMFC, since 2001. > More

"Mechanisms of catastrophic Battery Failure" by Nicholas Willard, University of Maryland
Battery failure can be generalized into two broad categories, slow progressive degradation and immediate catastrophic failure.
To date, most theoretical work has been performed on the former with little work focusing on how to model, predict, or mitigate the onset of catastrophic failure.
This presentation will explain the root cause mechanisms that lead to catastrophic failure and will offer solutions on how to better predict and handle this problem

Victor Cardona, Co-chair of the firm’s Cleantech Group stated, “Solar patents in 2011 reached levels 60% higher than 2010 and about three times those of 2009.
Solar vastly outperformed the other non-Fuel Cell sectors after hitting a record low in the third quarter of 2008.
Solar PV patents spiked in 2011 to record levels with Second Generation Solar PV patents topping the other generations of PV technology.
General Electric led the other Solar PV patent owners while Solar Thermal patents in 2010 were granted to 28 separate entities all with one patent each.”
The Shine On Solar edition analyzes the Solar sector and illustrates where patents are being granted within the Solar arena. This edition of our Shine On Solar edition analyzes solar energy trends in general with an emphasis on solar patenting trends in 2011.
As depicted below, Solar technology patents in continued to shine- reaching levels nearly three times that of 2009 and vastly outperforming the other non-Fuel Cell sectors after hitting a record low in the third quarter of 2008. >> More

New platinum-ruthenium alloy catalyst, Effectively removes carbon monoxide in hydrogen gas
A new alloy catalyst has been developed. An alloyness of the platinum-ruthenium (Pt-Ru) alloy catalyst (a degree of homogeneous mixture of platinum and ruthenium) is increased to a maximum level. The resultant catalyst is stable and has high catalytic activity. Where a trace of carbon monoxide is contained in the hydrogen gas as the fuel to the ENEFARM (residential PEFC CHP system in Japan), the CHP system is efficiently operable.
Additionally, a process in which the catalyzing function appears and the reason why the catalyst highly efficiently functions have been clearly explained with the aide of the tools, including the XAFC station and others in Photon Factory of High Energy Accelerator Research Organization. >> More
