In the process, the electrodes are suspensions of small particles carried by a liquid and pumped through different compartments of the battery.
"We realized that a better way to make use of this flowable electrode technology was to reinvent the lithium ion manufacturing process".
"In the new method, the electrode material remained in a liquid state. Having the electrode in the form of tiny suspended particles reduces the path length for charged particles as they move through the material, a property known as tortuosity.
Less tortuous path simplifies production and proves cost effective. The new system leads to the production of battery that is more flexible and resilient.

#EEJA and Tokyo U Achieve Simultaneous Formation of Contact Electrodes for P-type and N-type Organic semiconductor Crystals Using the Plating Method Tanaka Holdings, Co.,Ltd.
together with Professor Junichi Takeya of the University of Tokyo's Graduate school of Frontier Sciences, has achieved the world's first success in the development of technology for the simultaneous formation of contact electrodes for p-type and n-type*1
this technology enables the formation in the atmosphere of top contact-type OFET (figure 1)* 2 contact electrodes without the use of a vacuum environment,
Also, due to the emergence of high-performance n-type semiconductor materials in recent years, more advanced organic electronic devices can now be formed at a low-cost thanks to the simultaneous formation of contact electrodes for p-type and n-type
the contact resistance of the contact electrodes using this technology is 0. 1kiloohm-cm or less,
which is the lowest value currently on record in terms of the contact resistance of organic semiconductor contact electrodes formed in the atmosphere.
The atmospheric formation of a high-performance OFET (Figure 2) with low-contact resistance electrodes and high-mobility that are among the top levels in the world is achieved by combining the merits of this technology with those of high-performance
This result enables the atmospheric formation of organic electronic devices with high-speed drives and it enables the production of high functionality electronic devices using printed electronics*4. This technology is a process for the formation of contact electrodes with a gold-silver hybrid structure,
which is achieved by applying a silver catalyst solution for plating that includes silver nanoparticles to an organic semiconductor crystal, after
This enables the single-process formation of low-contact resistance contact electrodes for p-type organic semiconductors
While there are several methods for the formation of OFET contact electrodes they all suffer from such issues as requiring a vacuum environment
For example, thin film electrodes can be formed uniformly using the vacuum deposition method, but the equipment used to create a vacuum environment is incredibly expensive,
Also, while electrode formation in the atmosphere is possible using metallic ink and metallic paste,
in September 2014, EEJA together with Professor Takeya's research group jointly developed plating-process contact electrode formation technology for p-type organic semiconductors.
In order to stably form electrodes for organic semiconductor crystals, EEJA developed new gold nanoparticles as an electroless plating catalyst.
The contact resistance of the contact electrodes formed using this technology is 0. 7kiloohm-cm,
which is a remarkably low contact resistance for atmospheric formation contact electrodes. Also, Professor Takeya's research group developed a coating-type organic semiconductor that could be formed in a short time in the atmosphere with a large-surface thin film with uniform crystal orientation
This jointly developed technology contributes to technical innovation in connection to organic electronic devices. EEJA will continue to find further solutions for utilization in organic electronic devices.*
*1 p-type organic semiconductors and n-type organic semiconductors Organic compounds crystalized with uniform crystal orientation acquire the characteristics of a semiconductor.
*2 Top contact-type OFET This is an organic transistor where the contact electrodes are located on the semiconductor crystal.
However, because the electrodes are formed after forming the organic semiconductor crystal, the organic semiconductor is damaged easily, and contact electrodes are difficult to form.*
*3 Mobility This signifies the ease of movement for the charge within the semiconductor. Electronic devices that carry out complex processes require a higher mobility.
Until a few years ago, the mobility of organic semiconductors was generally about 0. 1cm2/Vs, but materials have been developed in recent years with a mobility of 10cm2/Vs or more.*
*4 Printed electronics This is a technology for the atmospheric formation of electronic circuits and devices on substrates using printing technology and so on.##
and reception at the same frequency in a wireless radio A team of Columbia Engineering researchers has invented a technology--full-duplex radio integrated circuits (ICS)--that can be implemented in nanoscale CMOS to enable simultaneous transmission and reception
transmitters and receivers either work at different times or at the same time but at different frequencies. The Columbia team, led by Electrical engineering Associate professor Harish Krishnaswamy,
So the ability to have a transmitter and receiver reuse the same frequency has the potential to immediately double the data capacity of today's networks.
Krishnaswamy notes that other research groups and startup companies have demonstrated the theoretical feasibility of simultaneous transmission and reception at the same frequency,
"The biggest challenge the team faced with full duplex was canceling the transmitter's echo.

#High performance, lightweight supercapacitor electrodes of the future Abstract: Researchers have developed a novel electrode to make low-cost, lightweight supercapacitors with superior performance,
a development that could mean faster charging time and longer battery life in electric vehicles and portable electronics.
Now two researchers from the S n. Bose National Centre for Basic Sciences, India, have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide
from AIP Publishing, the researchers report the fabrication technique of the hybrid nanostructure electrode. They also demonstrate its superior performance compared to existing, non-hybrid supercapacitor electrodes.
Since nickel oxide and iron oxide are environmental friendly and cheap materials that are widely available in nature,
the novel electrode promises green and low-cost supercapacitors in future.""This hybrid electrode shows the superior electrochemical performance in terms of high capacitance the ability to store electrical charge of nearly 1415 farad per gram, high current density of 2. 5 ampere per gram,
low resistance and high power density,"said Ashutosh K. Singh, the primary researcher at the Department of Condensed Matter Physics and Material Sciences at the S n. Bose National Centre
the electrode could retain nearly 95 percent of initial capacitance after cycling or charging and discharging 3, 000 times."
"The Promise of Supercapacitors Supercapacitors are used electronic devices to store an extremely large amount of electrical charges.
reliable and potentially safer power source for electric and portable electronic devices in future, said Singh.
How Scientists Built the New Electrode Inspired by previous research on improving conductivity via doping different metal oxide materials, Singh and Kalyan Mandal, another researcher and a professor at the S n. Bose
National Centre for Basic Sciences, mixed nickel oxide and iron oxide as a hybrid material and fabricated the novel core/shell nanostructure electrode."
"By changing the materials and morphologies of the electrode, one can manipulate the performance and quality of the supercapacitors,
and transporting ions through another material at the interface between electrode and electrolyte. Larger redox reaction surfaces are essential for achieving a higher power density for supercapacitors."
and electrochemical properties of the electrode, realizing high-performance supercapacitors,"Singh noted. How the New Electrode Performed Using techniques called cyclic voltammetry
and galvanostatic charge/discharge methods, Singh and Mandal studied the electrochemical properties of the hybrid material electrode.
Comparing with the counterpart, non-hybrid electrodes like nickel/nickel oxide and iron/iron oxide core/shell nanostructure electrodes, the hybrid material electrode demonstrated higher capacitance,
higher energy density and higher charging/discharging time.""For example, the current density of the hybrid electrode is three and 24 times higher than that of nickel/nickel oxide and iron/iron oxide electrodes, respectively,
"Singh said.""The comparative results show remarkable enrichment in the electrochemical activities of nickel/nickel oxide
and iron/iron oxide electrodes after combining them together, which suggests the hybrid electrode's better supercapacitive properties."
"One feature of Singh's fabrication technique is that it doesn't require extra binder materials.
According to Singh, binding materials are used commonly in the fabrication of carbon or graphene based supercapacitors for attaching redox active material on the current collector.
Without the mass of binding materials, the hybrid electrode is a good candidate to make lightweight supercapacitors."
and green supercapacitor electrodes for real life application, "Singh said. The researchers'next plan is to develop a whole supercapacitor device based on the hybrid electrode and test its functional performance,
