Inventory of 12 new battery technologies, which is the most powerful?

　　OFweek lithium battery is a kind of pretend that the energy produced by chemical reaction is directly converted into electric energy. It has the characteristics of stable voltage, stable current, long-term stable power supply, little influence from the outside world, simple structure, convenient carrying, simple charging and discharging operation, stable and reliable performance, and bringing a lot of convenience to modern social life.

　　1. Domestic super battery unveiled

　　Recently, Extreme Power Technology (Tianjin) Co., Ltd. demonstrated a super battery with endurance and charging ability that can be called "horror", and it only takes 3-5 minutes to fully charge once.

　　2, Honda commercial magnesium battery is here

　　It is understood that researchers who use magnesium in rechargeable batteries have encountered the same difficulties. During the process of charging, discharging, and discharging, the charging performance of magnesium will rapidly degrade. Based on this, the researchers developed a new material, vanadium oxide, It is applied to the positive electrode so that ions flow between the vanadium oxide and the magnesium negative electrode more easily. Vanadium oxide can increase the number of recharges of magnesium and prevent deterioration. In order to improve safety, the researchers added an organic substance, which can reduce the risk of fire in magnesium batteries.

　　3, lithium-sulfur battery

　　The lithium-sulfur battery that uses sulfur as the positive electrode of the lithium battery has the characteristics of high positive electrode capacity (theoretical value is 1675mAh/g), and it is expected to be a new generation battery. When the solar-powered aircraft maiden flight in 2008, lithium-sulfur batteries were used. During the day, the photovoltaic power generation panels on the solar-powered aircraft only provided the ability to fly, and the lithium-sulfur batteries were charged to maintain the power required for flight at night.

　　4, solid-state lithium battery

　　The main difference between solid-state lithium batteries and ordinary lithium-ion batteries is that it replaces traditional organic electrolytes with solid electrolytes. The traditional lithium-ion rechargeable battery using organic electrolyte may cause the electrolyte to heat up due to abnormalities such as overcharging and internal short circuit, which may cause spontaneous combustion or even explosion. Solid-state lithium batteries using solid-state electrolytes not only greatly improve safety, but also greatly improve their service life and energy density.

　　5. New type flow battery

　　Compared with the conventionally used rechargeable batteries, the flow battery has a larger scale. This is because the form and function of the flow battery are different from common lithium-ion batteries. In the flow battery cell, the liquid electrolyte circulates in two container boxes, and the two boxes are separated by a membrane. The ions travel through the membrane to achieve charge transfer, and the whole process is similar to the power generation principle of a hydrogen fuel cell. Flow battery packs are safer than lithium-ion batteries. Even if they are left for a long period of time, there will be no loss of electrical energy, so they are very suitable for storing renewable energy such as solar and wind energy.

　　6, liquid metal battery

　　Liquid metal batteries convert chemical energy into electrical energy through the oxidation-reduction reaction of liquid metal. The liquid metal is the characteristic of the battery. Utilizing the fluidity of the liquid, the liquid metal battery has high-rate charge and discharge performance and the scalability of the battery system. This also enables the liquid metal battery to meet the dual applications of energy and power. There are broad application prospects in large-scale energy storage.

　　A group of researchers from the Massachusetts Institute of Technology has developed a new type of all-liquid metal battery system, which is cheap and has a long service life. According to the research team, this device allows renewable energy sources such as wind and solar energy to compete with traditional energy sources.

　　7, leaf green battery

　　In the experiment, the team found that when oak leaves are heated to 1,000 degrees Celsius, their carbon-based structure will be disintegrated, and then the remaining material can contain electrolytes. Right now, the team is also testing other natural materials, including peat soil and banana peels.

　　8. Fast charge graphene battery

　　It is well known that the life of a battery will gradually decrease as the number of charge and discharge increases. Researchers at Swinburne University of Technology in Australia are trying to solve this problem. They have developed a new type of graphene battery. This battery not only has a super fast charging capacity (a few seconds), but also has an unusual durability. The R&D staff has set a lifetime for the battery. The use of graphene materials overcomes all the shortcomings of traditional batteries. At the same time, this product is also very environmentally friendly and inexpensive.

　　9. Batteries made of sugar

　　The Virginia Tech team developed a battery made of sugar, which has the advantage of super battery life. Researchers separated malt saccharin from sugar, which is the source of energy for this new battery. When maltose is in contact with air, the battery will release electrons to generate electricity. Because sugar is cheap and large in stock, this new battery has a lower cost. The most important thing is that it has degradable properties.

　　10. Nanowire batteries that cannot be charged

　　This battery was discovered by the researchers at the University of California accidentally. It makes traditional lithium batteries useless. Researchers used gold to make nanowires and then combined them with new materials. This combination greatly increases the number of charging and discharging of the battery, while the battery performance will not decrease with the increase in the number of charging.

　　11, self-destruct battery

　　The self-destruct battery is not for the mass market, but it can show its skills in special fields, and it also overcomes the previous problem of environmental pollution caused by disposable batteries. This battery was developed by Iowa State University and is mainly used for military purposes. It can be detonated with light, heat or liquid. In addition, even if it enters the water after detonation, it will not pollute the water body.

　　12, edible salt water battery

　　This battery takes the concept of environmental protection to the extreme. In order to justify the name of its own battery, AquionEnergy’s Witkeri actually ate a battery (it’s certainly not very tasty). The components of this battery are made of bio-derived materials, and they may be dust, cotton, carbon or salt water before transforming into a battery. However, this battery is not prepared for mobile devices. It has to do a "big business", such as a backup power source for a home or company, and it is provided with environmentally friendly wind or solar energy.
