2. Aiko's new N-type products were unveiled, opening the era of ABC mass production efficiency of 27%+!
On December 20, Aiko Co., Ltd. held a new product launch conference in Beijing with the theme of "Infinite Innovation and Efficient Duplex", and grandly launched the world's first high bifaciality ABC (All Back Contact) module - Stellar Series. The "Stellar Series" products released this time are AIKO's self-developed ABC high-efficiency modules, which are customized for centralized power station scenarios, with a bifaciality rate of up to 70%, breaking the industry's doubts about the low bifaciality of ABC modules. With the advantages of five breakthrough technologies, higher output power, local shading optimization, high temperature suppression, better temperature coefficient, and higher bifaciality, ABC modules can ensure higher comprehensive power generation for large-scale power stations, and thus bring more value sharing.
3. Norwegian startup achieves a breakthrough in solar energy storage using solid hydrogen
Norwegian startup Photoncycle has developed a groundbreaking solar energy storage technology that involves storing energy in a patented solid hydrogen solution. The company plans to install larger models of storage units near residential areas. Solar panels on the roofs of nearby buildings will provide the system with energy stored in the equipment, and the excess energy will be fed to the grid. The lack of storage of solar energy generated during the summer months has created a serious mismatch between production and consumption, as only about 50% of the electricity generated by the house is currently used. Photoshop aims to solve this challenge by storing surplus energy and releasing it when demand is high.
4. There has been important research progress in the field of energy storage Professor Xu Xijin's team at the University of Jinan synthesized NASICON-type cathode materials
The team of Professor Xu Xijin, Dean of the School of Physical Science and Technology of the University of Jinan, has made important research progress in the field of energy storage, and the relevant results have been reported as the cover article of the first issue of the Year of the Rabbit in Science Bulletin, a leading journal of China's Excellence Program. An advanced calcium-zinc hybrid ion battery was realized by coupling the dendrite-free zinc anode and the reversible de-intercalated sodium vanadium phosphate cathode, a Nasicon-type cathode material (nvp@ac@rgo) coated with amorphous activated carbon and reduced graphene oxide was synthesized for the reversible deintercalation of calcium ions, and a CA ZN ion hybrid battery coupled with the zinc-metal anode and the aqueous hybrid electrolyte was assembled.
5. Chang'an Energy Storage Research Institute: A breakthrough has been made in the research of hard carbon materials for anode of sodium-ion batteries
Recently, the Chang'an Energy Storage Research Group published groundbreaking research results in the journal Advanced Energy Materials. They have successfully broken through the limitations of hard carbon in terms of energy storage capacity and charge-discharge efficiency by using a unique carbon dioxide etching strategy, providing new ideas for the iteration of sodium-ion battery technology. The CO2 etching process was introduced into starch-derived hard carbon materials, which not only enlarged the scale of the closed pores, but also increased the capacity and maintained the morphology of the microspheres. This technology enables a significant increase in the sodium storage capacity of hard carbon materials.
6. Japanese scientists have developed a new type of aluminum battery
According to the "Nihon Keizai Shimbun" on December 21, Chiba University in Japan has developed a battery made of abundant metal aluminum. Compared with lithium batteries, aluminum batteries face a lower risk of resources**, and under the same weight conditions, aluminum batteries can store several times more power than lithium batteries. The battery uses sulfur materials as the positive electrode and aluminum as the negative electrode, which is easier to conduct electricity and has a longer battery life. Content on the web.
