In this era of race against time, everyone is working hard to expand, seize the market, invest in research and development, battery development can be described as ever-changing, do not want to fall behind, you must pay attention to the latest industry news, real-time understanding of the most advanced battery technology, today Xiaobian Let’s summarize what new batteries are there! 1, solid state battery Solid-state batteries are extremely promising new-generation power batteries. They are called subversive technologies. Their safety is better than lithium batteries and their energy density is high. It is considered to be the best choice for solving the energy life of new energy vehicles. Samsung Giant companies such as Tesla are already in mass production. Although there are still many technical problems, the electrode current density and the like are subject to many restrictions, and the mass production scale and price competitiveness are not as good as lithium batteries. However, recently, electric car dealer Fisker Motors announced a breakthrough, the patent shows that its newly developed solid-state battery for vehicles can be fully charged in one minute, and the car can travel 500 miles per charge. 2, fuel cell A fuel cell is a power generation device that directly converts the chemical energy of a fuel and an oxidant into electrical energy through an electrochemical reaction. The isothermal electrochemical method directly converts chemical energy into electrical energy without going through a heat engine process, and is not limited by the Carnot cycle. The energy conversion efficiency is high, and there is no noise and no pollution. It is becoming an ideal energy utilization mode. In theory, it can operate at nearly 100% thermal efficiency, which is highly economical. Fuel cell units contain little or no moving parts, are reliable, require less maintenance, and are quieter than conventional generator sets. In addition, the electrochemical reaction is clean, complete, and rarely produces harmful substances. All of this makes fuel cells a highly promising energy powerplant. 3, lithium air battery South Korea's Samsung Electronics will develop a third-generation rechargeable battery for pure electric vehicles. The battery life of a single charge will be nearly twice that of current lithium-ion batteries for pure electric vehicles. It is planned to commercialize lithium-ion batteries in 2030. The lithium-ion battery recently developed by Samsung Labs has a capacity of 520 watts per kilogram and is considered the holy grail of the industry. According to the Nikkei News, if Nissan's latest Leaf electric vehicle uses Samsung's lithium-ion battery, the maximum range can be increased from 400 kilometers to more than 700 kilometers. 4, lithium sulfur battery 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. A lithium-sulfur battery using sulfur as a positive electrode of a lithium battery has a high positive electrode capacity (theoretical value is 1675 mAh/g), and is expected as a new generation battery. In the first flight of the solar-powered aircraft in 2008, lithium-sulfur batteries were used. During the daytime, the photovoltaic panels on the solar-powered aircraft provided only flight capacity and charged lithium-sulfur batteries to maintain the power required for night flight. 5, graphene battery As the “king of new materialsâ€, graphene is the newest nanomaterial that has been found to be the thinnest, lightest and strongest in the world. Its specific excellent electrochemical energy storage characteristics, ultra-fast charge and discharge, cyclic charging, etc., are expected to bring subversive changes to automotive power batteries. Therefore, graphene battery research has also been favored by many companies and the country's attention. At present, Polycarbon and Harbin Institute of Technology have developed graphene polymer materials that store three times as much energy as conventional battery products. Electric vehicles that use this battery to provide electricity can travel more than 1,000 kilometers, charging time is greatly reduced, and charging times can reach more than 3,000 times. The weight is less than half of the traditional rechargeable battery. Although these data are still in the experimental stage, there is no doubt that graphene will become the key to breaking the storage bottleneck of new energy vehicles, creating longer cruising range and further developing and popularizing. 6, the new thin film battery Scientists at Dracula Technologies in France have developed a new technology that uses light as a new energy response and then charges your phone. This is a decal solar cell consisting of a unique conductive plastic that captures energy from outdoor sunlight or indoor artificial light. The thin-film battery has the advantages of light weight, non-toxicity, folding, and low cost. The developer said that a square-shaped thin-film battery with a length and width of about 5 cm can be printed in an hour and can be customized according to shape and color. This means we can print this thin-film battery on a T-shirt or backpack with a larger exposure area and then charge your phone in other ways. However, these foldable sheets are not costly and can be manufactured using inkjet printers, making this technology more versatile. 7, sodium-based battery According to the US "Qiaobao.com", researchers at Stanford University have developed a sodium-based battery that can store as much electricity as a lithium-ion battery, but at a much lower cost. Related 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 richer elements such as sodium to develop higher performance and lower cost batteries. Currently, the cost of mining one ton of lithium is about $15,000, while the cost of mining one ton of sodium is only $150. In newly designed sodium-ion batteries, sodium ions can be attached to inositol, a common compound that can be extracted from liquid by-products from rice bran or corn processing. The new combination of sodium and inositol significantly improves the ion cycling of sodium-based cells, allowing ions to move more efficiently from the cathode through the electrolyte to the phosphorous anode, which in turn produces a stronger current. 8, water-based lithium battery According to foreign media reports, a team of Chinese scientists at the University of Maryland recently developed a new lithium-ion battery based on water-based electrolyte, which not only meets the standards required for home electronic products such as notebook computers for the first time in voltage. At the same time, the danger of fire and explosion can be avoided. The researchers used a new polymer coating that had special drainage properties, and after it was applied to the electrodes, water molecules could not get close to the electrode surface. After the first charge, the gel decomposes into a stable interface that isolates the electrode from the electrolyte and prevents water molecules from decomposing at the operating voltage. This technology not only improves the energy storage and charge and discharge performance of the battery, but also completely avoids the danger of the organic solvent electrolyte being explosive. 9, super capacitor battery Recently, NAWA Technologies announced that it has developed five times the power of ultra-fast carbon batteries, which can greatly enhance the power of super-capacitor batteries, and many auto companies are interested in such batteries. NAWA said that the transmission speed of "ultra-fast carbon battery" is 30-100 times that of lithium-ion battery, but the stored energy is only 10-20% of lithium battery, which is a disadvantage. For this reason, Ge Weikai will promote the "hybrid system". What advantages does it have? Supercapacitors can increase the acceleration, and when the car slows down, it can recover energy and let the lithium battery car run farther. Supercapacitors can be charged again and again without damage. It can withstand the impact of instantaneous power and power regeneration, and extend the life of lithium batteries. The technical principle of NAWA is similar. NAWA's goal is to supply batteries to high-end European manufacturers, which will be fully operational in 2022. 10, liquid metal battery A liquid metal battery converts chemical energy into electrical energy through a redox reaction of a liquid metal. The liquidity of the metal is the characteristic of the battery. The liquid metal battery has high rate of charge and discharge and the scalability of the battery system. This also enables the liquid metal battery to meet both energy and power applications. Large-scale energy storage has broad application prospects. A team of researchers from the Massachusetts Institute of Technology has developed a new all-liquid metal battery system that is inexpensive and has a long service life. According to the research team, the device allows wind and solar renewable energy to compete with traditional energy sources.
