the idea of developing new batteries for electric vehicles with trees has been questioned by many scientists. But a Japanese paper maker is determined to try to develop the technology. According to foreign media reports, Nippon Paper Industries Co is committed to making new breakthroughs in the use of cellulose nanofibers, with the aim of manufacturing capacitors that can store and release more energy than existing batteries, thereby greatly improving performance and reducing the impact on the environment. Among them, cellulose nanofibers are materials produced by refining wood pulp to a size of 1% micron or less, and are currently used in products such as diapers or food additives

Toru Nozawa, CEO of Nippon Paper Industry Corporation, said, "we must speed up our cooperation with other companies to find practical applications. Supercapacitors based on cellulose nanofibers or CNF (carbon nanofibers) can be used in lithium-ion battery applications, such as automobiles and intelligence."

supercapacitors keep massless electrons in the electric field, while batteries store energy in chemical form. This difference shows that supercapacitors are very suitable for providing short and strong energy bursts (such as the burst sound of camera flash), but their storage capacity is only a small part of that of lithium-ion batteries

for decades, according to the measurement type, superelectric has been divided into fatigue testing machine, creep testing machine and other containers, which play an important role in special application fields, such as memory backup system for notebook computers, pitch control of wind turbine motors, or regenerative braking of some hybrid and plug-in vehicles. In addition, the company also made a commitment to launch the energy storage system, which can not only greatly shorten the charging time and reduce safety risks, but also achieve zero dependence on precious metals such as cobalt or nickel

industry consultant Sam Jaffe said, "as a technology, supercapacitors still have great potential for sustainable development, but compared with batteries, they are in a completely different technical field. Therefore, supercapacitors and lithium-ion batteries will never become competitors." Mikio Fukuhara, a researcher at Northeastern University who cooperates with Japan Paper Industry Corporation, said that the energy density has been improved. By using CNF, this component can also make significant progress

in a paper in the journal Nature in March, Fukuhara and other scientists proved that the supercapacitor that uses the C main thread to mainly process the human-machine interface NF can be used to store a large amount of power, and can be applied to the storage of handheld electronic products, transportation and renewable energy. Fukuh can prepare SiC particle reinforced MoSi2 matrix composites. Ara said that the early use cases used low-voltage devices, such as smartphones or watches. The deployment of supercapacitors in electric vehicles from 2014 will be the "final application". Therefore, capacitors need to make progress in other aspects, partly because cars will use high voltage

fukuhara said: "I am confident that supercapacitors will replace lithium-ion batteries in the future, and will become a decisive factor in protecting the environment and guide a new industrial revolution." "Even the supercapacitor development competitors of other projects are very confident about this." Professor Yoo Seung Joon, a laboratory of electromechanical chemistry and energy materials at Kwangju Institute of technology in South Korea, said: "after the development is completed, this technology will be used to improve the capacity and service life of electric vehicles and energy storage systems

Nippon Paper Industry Corporation is also seeking development opportunities to provide materials to existing battery manufacturers while continuing to develop competitors' technologies. Nozawa said that the company has at least one leading manufacturer as a customer and is considering establishing supply centers in emerging markets such as Europe. Nozawa said, "the development of electric vehicles is bound to accelerate, so we must keep up with the development trend."
