Some people say that the key to new energy technology is batteries. Indeed, whether it is new energy vehicles, mobile phones and other electronic products, or even the emerging UAV, battery is one of the most important factors restricting product performance. In order to achieve breakthroughs in the field of batteries, both the battery as a whole and the components of batteries are the focus of research and development. New technologies and new materials have been applied continuously.
Japan's National Institute of Material Science recently announced that a new type of lithium battery with very high energy density has been developed, which is called "lithium air battery". Its energy density per unit volume is close to the limit, and its cost can be well controlled. According to the organization, "lithium air batteries" use carbon nanotubes as air electrode materials, through the optimization of the electrode structure, can achieve a high energy density, 15 times more than ordinary lithium batteries. Researchers at the organization said that the current "lithium air battery" is only a test product, and will continue to optimize design in the future to further improve energy density.
Battery endurance is one of the most important indicators. The world's first solar-powered cell phone battery has come out recently. The battery, called Hybbi, consists mainly of lithium-ion batteries and solar modules. This charging method has very low energy loss and is twice as efficient as other solar charging products. Hybbi solar panels are covered with gorilla glass and cut by laser. The thickness of the panels is less than 1 mm. In the case of direct sunlight, the charging speed can reach 20% per hour.
At the same time, new technologies have also been applied to the development of battery materials. Toyota has announced that it will invest $35 million in research and development of new energy battery materials in the next four years. In Toyota's view, artificial intelligence will be the key way to find new energy future materials. As a new method, the computational model based on artificial intelligence has recently been applied to the study of material science. It may take decades to find new materials manually, but this process can be accelerated by incorporating artificial intelligence technology into computational models.
Inspired by the structure of trees, engineers at the University of Maryland in the United States modified wood as a special structure for lithium-metal battery anodes to avoid battery failures caused by some key factors. They proposed a new design for storing lithium ions in batteries in natural channels used to transport water and nutrients in wood. The resulting battery is very safe and can be charged and discharged quickly.
