1. Nickel -metalized battery system of Type I (OH) 2

　　Because of its number of electrons that transform the number of electrons to the Y -type NIOOH than β, it has always been a hot spot for the research of new materials. At the same time, it is considered to be the most ideal nickel -metalized battery positive pole material during the transformation of Type A when transforming to Y. Essence Its weakness is the instability in the strong base solution, which is easily transparent and transformed into β hydrocarbon nickel. At the same time, its loosening density is too small to achieve the needs of filling. Solving these two problems will be the focus of technological development research. Essence

　　2.AB2 hydrogen storage alloy powder in nickel -metal hydride battery system

　　The AB2 hydrogen storage alloy powder is considered an ideal negative electrode material. The capacity of 420mAh/G has always been a research hotspot, but its service life is short and low -temperature performance. The research on improving these two technologies targeted is the focus.

　　3. Battery width temperature range

　　By studying the oxides of CA, Y, ER, TI, TM, and the composition and matching ratio of electrolytes in the positive electrode, improve the nickel electrode oxygen analysis level to improve the rechargeability of batteries at high temperatures, especially in high temperatures, especially in high temperature, especially The charging efficiency in large current, thereby reducing the thermal effects caused by oxygen generation and composite in the system; reducing the internal resistance of the system in the production of battery production

　　Microelectronics chemical polarization, thickness polarization and ohms polarization to reduce the generation of corresponding heat. Reduce the thickness of the single battery, design a proper battery gap and be equipped with a cooling system to facilitate the distribution of battery heat, and at the same time equipped with the thermal management system. Choosing a highly hydrogen storage alloy with high drilling content to reduce the pressure of negative hydrogen analysis platforms is also the main solution to the application of battery high temperature performance. The main problem used at low temperatures is negative. The use of a richly stored hydrogen storage alloy, and the use of low diamond alloys and high diamond alloy can effectively improve the performance of negative electrodes at low temperatures.

　　4. Battery fast charging technology

　　The battery must be able to solve the problem of end pressure and fever in the battery. To reduce the internal pressure of the battery, it is necessary to improve the analogenic oxygen analysis, improve the efficiency of positive charging, and inhibit the oxygen generated by the positive charging. By adding diamond additives in the positive electrode, and adding substances that improve the positive charging efficiency to the electrolyte, the improving the reserved capacity of the negative electrode and the surface treatment of the negative electrode are effective ways to reduce the internal pressure of the battery. Adjust the battery pre -charging capacity, increase the capacity of the negative activation and the battery's negative pre -charging amount and reservation, keep the negative reservation of the negative electrode, so that the negative electrode will maintain a good absorption of hydrogen when the positive electrode is overcharged, and improve the positive charging charging. Efficiency and setting cooling device on the combined structure are also a way to solve the problem of fever to increase battery charging speed.
