[Abstract]:In order to improve the electrical performance and safety of lithioyl chloride primary battery, the main aspects affecting the performance of lithioyl chloride battery are studied in this paper. The battery can meet the requirements of the relevant military standards and users. Through the characterization of acetylene black, a cathode material with the best performance, the specific surface area and conductivity of the electrode can be improved. The binuclear metal phthalocyanine complexes of highly active electrocatalyst were characterized and the optimum additive morphology and dosage were determined to increase the working voltage and capacity of the battery and reduce the voltage lag problem of the battery. By studying the appropriate safety electrolyte additive and selecting the best dosage of additive, the safety of lithioyl chloride battery under the condition of abuse is improved, and the positive forming process of the battery is optimized through the improvement of the new process. To improve the specific surface area of the cathode electrode, colleagues improve the production process of stainless steel shell, the sealing process, the diaphragm process, the winding process, the liquid injection process for the battery, for the common problems in the production and use of the battery. It improves the production efficiency of the battery, improves the problems in the use and storage of the battery, improves the performance and production capacity of the battery in an all-round way. After defining the materials and processing technology with the best performance, the sample battery is trial-produced. Test the performance and safety of lithium battery according to relevant test requirements. The experimental results show that the improved lithioyl chloride battery has better performance than the conventional battery, such as battery capacity, voltage lag and so on. At the same time, the battery safety can also meet the relevant requirements of military standards and user requirements.
