SMM News: the core of electric travel is rechargeable battery technology, which has made great progress in charging time and efficiency in the past few years. Now, players in this field are still trying to find different types of rechargeable battery technology to power electric vehicles, as well as looking for a variety of power sources, such as regenerative braking systems that power rechargeable batteries. It is worth mentioning that the key factor in choosing an electric car is mileage. Through the efforts of automobile manufacturers, vehicle mileage has been optimized and is expected to be further developed on the basis of existing technology. Here are the players' major innovations and achievements in the field of battery technology.
Hyundai: the company is developing solid-state rechargeable batteries and has begun trial production at its Nanyang R & D center, (Namyang R & D Center). The company shifted its focus from hydrogen fuel cells to electric cells, powering the plug-in hybrid (PHEV) and the all-electric (BEV).
Bosch: Bosch acquired Seeo Inc, a California-based solid-state battery company. The company plans to enter the manufacturing field of rechargeable batteries, developing 50kWh lithium-ion battery packs that weigh about 190kg. In addition, the license for lithium polymer batteries was obtained from Lawrence Berkeley National Laboratory (Lawrence Berkeley National Laboratory).
Fisker Automotive: the company is working on solid-state rechargeable batteries with three-dimensional electrodes. Its energy density is expected to be more than 2.5 times that of traditional rechargeable batteries and can last 500 miles in one minute.
BMW: BMW has partnered with Solid Power ((Colorado) to develop solid-state rechargeable batteries. The company integrates lithium-ion batteries with high-capacity metal lithium negative electrodes, which will provide three times more energy capacity than conventional batteries.
Dyson: Dyson is a vacuum cleaner manufacturing company that entered the rechargeable battery manufacturing field by acquiring Sakti3, which operates solid-state rechargeable batteries. The company plans to build a battery manufacturing plant and launch its own electric car in 2020.
Toyota: the company plans to launch its first electric vehicle based on solid-state rechargeable batteries in 2022. The company attaches great importance to solid-state rechargeable battery technology and is expected to increase vehicle mileage compared with vehicles currently on the road.
Ohio State University: researchers at Ohio State University have designed a thin film that allows the battery to charge quickly and stop Discharge when it's not working. According to reports, this smart membrane technology combines polycarbonate filters and conductive polymers, or will create a powerful redox transistor battery.
American Battery 500 Alliance: this alliance, which includes four U.S. Department of Energy national laboratories and five universities, aims to increase the specific energy of batteries to three times that of current technology. This will propel electric vehicles to achieve 1000 cycles and make lighter, smaller and cheaper battery packs.
Storedot, Israel: the company's goal is to develop a new type of car battery using organic compounds in (flash battery), a mobile phone flash battery. The electric vehicle's flash battery can be recharged in about five minutes, enabling the vehicle to travel 480 kilometers, the company said.
Changchun Institute of Applied Chemistry: researchers at the institute have launched a "proof-of-concept" design for capturing atmospheric nitrogen. Such batteries operate at room temperature and are recharged by the reaction of nitrogen with lithium, taking into account the nitrogen in the atmosphere.
Enevate: the company has developed a silicon-based lithium-ion battery that is expected to charge and discharge safely below minus 40 ℃, capture more energy during regenerative braking and extend mileage in cold climates. The company is expected to license its silicon-based technology to battery and electric car makers.
