Who is the future direction of new energy batteries?

Classification:


【概要描述】New material batteries are constantly emerging, which one can become the future direction? Gao Fei, Deputy Director of the Technology Center of Honeycomb Energy Technology Co., Ltd., stated that the development of lithium batteries has become a consensus in the industry as resource reserves are gradually incorporated into the strategic resources of various countries. At present, sodium batteries have advantages such as low price and good performance. Sodium batteries have excellent low-temperature performance, which is better than lithium iron phosphate batteries. But the core volume energy density is too low, and grid energy storage and lightweight power are its core development directions.

New material batteries are constantly emerging, which one can become the future direction? Gao Fei, Deputy Director of the Technology Center of Honeycomb Energy Technology Co., Ltd., stated that the development of lithium batteries has become a consensus in the industry as resource reserves are gradually incorporated into the strategic resources of various countries. At present, sodium batteries have advantages such as low price and good performance. Sodium batteries have excellent low-temperature performance, which is better than lithium iron phosphate batteries. But the core volume energy density is too low, and grid energy storage and lightweight power are its core development directions.

As the price of lithium batteries increases, the attention to sodium batteries has increased. As an established battery company, Lin Jian, a scientist at Bicke Power Battery Co., Ltd., believes that the cost of sodium ion batteries is much lower than that of lithium batteries. The cycling stability of sodium ion batteries is comparable to that of lithium battery NMC, and with the advancement of materials, the cycling performance can be further improved. The rate and low-temperature discharge performance of sodium ion batteries are significantly better than those of lithium batteries. The performance of sodium ion batteries is between that of lithium batteries and that of iron lithium batteries.

Yue Min, Chairman and President of Shenzhen Yanyi New Materials Co., Ltd., believes that sodium ion batteries are currently very hot, and they will be the first to be industrialized after lithium batteries. However, there are still many problems that need to be solved, and industrialization will not be as optimistic as expected. If the sodium ion battery cannot recover within three years, it will greatly affect the pace of industrialization. Because lithium prices are so high now, if sodium ion batteries cannot still afford it, when the price of lithium carbonate drops to within 150000 per ton, the development of sodium electricity will still be affected.

Hydrogen energy is also a subject of concern. The country should accelerate its layout and increase research and development. In the short term, individuals are not optimistic about fuel cells. The overall trend of the development of the new energy industry will not change, but the industrial layout has become severely surplus, and fierce competition will become the norm, "said Yue Min.

Peng Suping, academician of the CAE Member, said that the country hopes to use less fossil energy and more renewable energy, but China's endowment is mainly fossil energy, and low-carbon utilization of fossil energy is a long-term national policy. The development of hydrogen energy is the development of fuel cells, which has raised the development and utilization of hydrogen to new heights. Hydrogen energy will be an important path for China's low-carbon energy development. Hydrogen energy can be used as both energy and energy storage. Hydrogen energy is an important component of the country's future energy.

The gradual withdrawal of traditional energy must be based on the reliable replacement of new energy. The next 10-20 years will be an important opportunity period for the development of China's hydrogen energy and fuel cell industries. It is necessary to closely connect with China's energy development reality, actively plan from strategic, policy, technology, funding, international cooperation, and other aspects, solve development problems through reform and innovation, and help achieve high-quality development of hydrogen energy and fuel cells. "Peng Suping believes.

Characteristics of New Energy Vehicle Batteries

Lithium batteries are a general term for chemical power sources that use metallic lithium or lithium containing substances as negative electrodes. It is a new type of high specific energy battery system that has been developed in the past decade. The idea of using active metals such as lithium and sodium as negative electrodes for batteries was first proposed by a researcher born in 1958 at the University of California in the United States. In the 1970s, Yasuro Fukuda of Panasonic Electric Company in Japan first invented and applied lithium fluoride carbon batteries. From then on, lithium batteries gradually moved from experimental research to practicality and commercialization. Due to the excellent performance of lithium batteries, various countries are competing to develop various new types of lithium batteries to meet military and consumer needs, such as lithium iodine batteries (1972), lithium chromate batteries (1973), lithium sulfur dioxide batteries (1974), lithium sulfite chloride batteries (1974), lithium copper oxide batteries (1975), lithium manganese dioxide batteries (1976), lithium molybdenum disulfide batteries (1989), lithium-ion batteries (1991), and lithium manganese dioxide batteries (1994). Especially in the early 1990s, the high specific energy and long life lithium-ion batteries invented and launched by Sony Energy Technology in Japan greatly promoted the development of the lithium-ion battery industry.
