The concept of using water-based electrolytes for battery safety is not new. However, this type of design is more flammable than lithium batteries and is much less expensive, but it also brings about problems such as shorter life, lower power consumption, etc., for consumer electronics products. It's like a pig teammate.
However, research teams from Korea Institute of Science and Technology (KAIST) and Kangwon University in Korea have developed breakthrough equipment. According to the “Interesting Engineering” report, this is the first time that scientists have effectively solved the problem of water-based capacitors and their charging. Speed and high energy density limitations. In addition, this device can achieve a high degree of stability while achieving performance goals.
Basically, the team devised an entirely new cathode-anode structure with a series of different materials. The anode was made of a network of graphene polymers, with a high surface area to store more energy and cathodes from graphene Due to the high energy density, the energy loss between the two electrodes is minimized. After more than 100,000 redox cycles, the capacitance remains about 100%.
Compared with lithium batteries, water-based batteries are more environmentally friendly and easier to manufacture. If they are combined with high capacitance and high stability, they can be quickly recharged. The commercialization road will be smoother. According to Interesting Engineering, related industries are bound to The team will respond to this innovative development. The study was published in the "Advanced Energy Materials" journal.
