The application of nanometer titanium dioxide RT50S independently produced by Dassinon Nano in the field of battery electrodes is mainly reflected in improving the performance and safety of batteries. The following is a detailed analysis of the application of nano-titanium dioxide RT50S in the field of battery electrodes:
1, improve battery cycle life: nano-titanium dioxide RT50S can reduce the capacity attenuation of the battery during the cycle process and improve the cycle life of the battery. 예를 들어, the fumed nano-titanium dioxide RT50S is added to the silicon carbon negative electrode of the lithium battery, and the nano-titanium dioxide RT50S is wrapped in the silicon carbon negative electrode material through the mechanical fusion machine. The experimental results show that the battery capacity after addition is maintained at 92.8% of the initial capacity, and the decay ratio is 7.2%. The blank sample battery capacity without addition is maintained at 80.5% of the initial capacity, and the attenuation ratio is 19.5%.
2, inhibit the growth of lithium dendrites: nano-titanium dioxide RT50S has high surface energy and small grain size, which can inhibit the growth of lithium dendrites and reduce the short circuit phenomenon inside the battery, thereby improving the safety performance of the battery.
3, improve battery performance: nano-titanium dioxide RT50S is regarded as the most potential to replace graphite-based negative electrode material, because of its good stability, low volume expansion (3-4%), high operating voltage and low cost. The electrochemical performance of lithium-ion batteries can be significantly improved by the functional treatment of nano-scale titanium dioxide materials and the grinding of carbon black together to prepare the electrodes of lithium-ion batteries.
4. Modification research: nano-titanium dioxide RT50S itself has the shortcomings of poor ionic conductivity and low electrical conductivity, which limits its further development. 그러므로, the researchers improved the conductivity and ion transport ability of nano-titanium dioxide RT50S through its own modification, such as crystal face and shape control, and composite with highly conductive materials.
5. Controllable morphological transformation: By introducing conductive materials such as carbon nanotubes (CNTs), controllable morphological transformation of nano-titanium dioxide RT50S can be achieved to improve its dispersion and conductivity in the battery electrode. This composite structure provides an interconnected conductive network for the rapid diffusion of lithium ions and electrons, thereby improving the battery’s cycle performance and high-speed rate performance.
요약, the application of nano-titanium dioxide RT50S in the field of battery electrodes is mainly reflected in improving the cycle life, safety and performance of the battery. By means of modification study and controlled morphological transformation, the performance of nano-titania RT50S in battery electrode can be further optimized, which provides strong support for the development of battery technology.
