　　4. Lithium-sulfur lithium ion battery 18650

　　Lithium-sulfur batteries are expected to become an alternative to lithium-ion batteries due to their high theoretical capacity, high energy density, abundant reserves, low cost and environmental friendliness.

　　Lithium-sulfur batteries using sulfur as the positive electrode of lithium batteries have the characteristics of high positive electrode capacity (theoretical value is 1675mAh/g), and are highly anticipated as a new generation of storage batteries.

　　When the solar aircraft made its maiden flight in 2008, lithium-sulfur batteries were used. During the day, the photovoltaic panels on the solar aircraft only provide power for flight, and charge their lithium-sulfur batteries to maintain the power required for night flights.

　　5. Graphene lithium ion battery 18650

　　Graphene, as the "King of New Materials" with high hopes, is the thinnest, lightest and strongest new nanomaterial discovered in the world.

　　Its excellent electrochemical energy storage characteristics, ultra-fast charge and discharge, cycle charging, etc. are expected to bring disruptive changes to automobile power batteries. Therefore, graphene lithium ion battery 18650 research has also been favored by many companies and valued by the country.

　　At present, the graphene polymer material lithium ion battery 18650 developed by Jucarbon and Harbin Institute of Technology can store three times the energy of traditional lithium ion battery 18650 products. Electric vehicles powered by this lithium ion battery 18650 can travel more than 1,000 kilometers. The charging time is greatly reduced, and the number of charging times can reach more than 3,000 times. The lithium ion battery 18650 The weight is less than half that of traditional rechargeable batteries.

　　Although these data are still in the experimental stage, there is no doubt that graphene will become the key for new energy vehicles to break through the lithium ion battery 18650 storage bottleneck, create longer cruising range, and further develop and popularize.

　　6. New thin film batteries

　　Scientists at French company Dracula Technologies have developed a new technology that uses light as a new energy reaction to then charge your phone.

　　This is a decal solar cell composed of a unique conductive plastic that can capture energy from outdoor sunlight or indoor artificial light. The thin-film lithium ion battery 18650 is lightweight, non-toxic, foldable, and low-cost.

　　Developers say that a square thin-film lithium ion battery 18650 about 5 centimeters long and wide can be printed in just one hour and can be customized according to shape and color.

　　This means we can print this thin-film lithium ion battery 18650 on a T-shirt or backpack with a larger exposure area, and then charge your phone through other methods. However, these foldable sheets are inexpensive and can be made using an inkjet printer, making the technology more versatile.

　　7. Sodium-based batteries

　　According to the American "Qiaobao.com", researchers at Stanford University have developed a sodium-based lithium ion battery 18650 that can store as much electricity as lithium-ion batteries, but at a much lower cost. Relevant research findings have been published in the journal Nature Energy.

　　Researchers point out that lithium is the best choice for making batteries, but lithium has become rare and expensive, and humans need to use other more abundant elements, such as sodium, to develop higher-performance and low-cost batteries. Currently, the cost of mining a ton of lithium is about $15,000, while the cost of mining a ton of sodium is only $150.

　　In the newly designed sodium-ion lithium ion battery 18650, the sodium ions attach to myo-inositol, a common compound that is extracted from rice bran or a liquid byproduct of corn processing.

　　The new combination of sodium ions and myo-inositol significantly improves ion cycling in sodium-based batteries, allowing ions to move more efficiently through the electrolyte from the cathode to the phosphorus anode, which in turn generates stronger current.

　　8. Water-based lithium lithium ion battery 18650

　　According to foreign media reports, a team of Chinese scientists at the University of Maryland in the United States recently developed a new lithium-ion lithium ion battery 18650 based on water-based electrolyte. Not only did the lithium ion battery 18650 reach the voltage required for home electronics such as laptops for the first time, it also It also avoids the risk of fire and explosion.

　　The researchers used a new type of polymer coating, which has special drainage properties. After coating it on the electrode, water molecules cannot get close to the electrode surface. After the first charge, the gel breaks down into a stable interface that isolates the electrodes from the electrolyte and prevents water molecules from breaking down at the operating voltage.

　　This technology not only improves the energy storage and charge and discharge performance of the lithium ion battery 18650, but also completely avoids the danger of explosion of organic solvent electrolytes.

　　9. Supercapacitor lithium ion battery 18650

　　Recently, NAWA Technologies announced that the "ultra-fast carbon lithium ion battery 18650" it has developed is five times more powerful than standard supercapacitor batteries and can greatly enhance the power of supercapacitor batteries, making many automobile companies interested in this kind of lithium ion battery 18650.

　　NAWA said that the transmission speed of "ultra-fast carbon batteries" is 30-100 times that of lithium-ion batteries, but the energy stored is only equivalent to 10-20% of lithium batteries, which is a disadvantage.

　　Because of this, Ge Weikai promoted the "hybrid system". What are its advantages? Supercapacitors can increase acceleration. When the car decelerates and brakes, it can recover energy, allowing lithium lithium ion battery 18650 cars to run farther.

　　Supercapacitors can be charged again and again without damage. They can withstand the impact of instantaneous power and power regeneration, extending the life of lithium batteries. The technical principles of NAWA are generally similar. NAWA's goal is to provide batteries to high-end European manufacturers and start full production in 2022.

　　10. Liquid metal lithium ion battery 18650

　　Liquid metal batteries convert chemical energy into electrical energy through the redox reaction of liquid metal. The characteristic of the lithium ion battery 18650 is that the metal is in a liquid state. Taking advantage of the fluidity of the liquid, the liquid metal lithium ion battery 18650 has high-rate charge and discharge performance and the scalability of the lithium ion battery 18650 system. This also enables the liquid metal lithium ion battery 18650 to meet the dual applications of energy and power, and is widely used in large-scale applications. There are broad application prospects in large-scale energy storage.

　　A team of researchers from MIT has developed a new all-liquid metal lithium ion battery 18650 system that is cheap to build and has a long service life.

　　According to the research team, this device could allow renewable energy sources such as wind and solar to compete with traditional energy sources.
