402030 battery

release time:2024-05-20 Hits: Popular:AG11 battery

　　Columbia University develops new 402030 battery

　　Inspired by the structure of biological spines, Guoyu Qian and others at Columbia University developed a flexible lithium-ion battery that maintains good flexibility while maintaining the advantage of high volumetric energy density.

　　The basic structure of a flexible battery can be divided into a trunk and branches connected to the trunk. These branches will be wound around the trunk, eventually forming a structure similar to an animal spine, which is connected to the external circuit by the trunk. Such a structure not only ensures good flexibility of the battery, but also greatly improves the energy density of the flexible battery. When LiCoO2/graphite is used as the active material, the volume specific energy of the battery with this structure can reach 242Wh/L.

　　In the electrochemical performance test, the cycle performance of the battery with this structure was not affected whether it was bent (bending radius 20mm, 10,000 times) or twisted (twisted 90 degrees 1,000 times), and cycled 100 times at a rate of 0.2C , the capacity retention rate can reach 94.3%, and the Coulomb efficiency reaches 99.9%.

　　Comment: To be honest, although wearable devices such as Bluetooth headsets have become more common, "smart clothing" with flexible batteries as the core is still far away. A friend told me during the chat that the current smart coat, not to mention cost control, has very low reliability. In particular, folding and cleaning will cause great damage to the battery. Therefore, this friend is trying to transfer the battery to the belt. , the current sample weighs 7 pounds and cannot be used yet. Therefore, as a consumer, don’t expect too much and just buy traditional clothes honestly.
