The structural energy is combined into the battery portion of the system with the load-bearing structure portion integrally formed by the multi-functional structure, which in the energy supply at the same time satisfy the corresponding force requirements, so as to achieve the purpose of integration of structural bearing force and energy supply . Shaped polymer lithium-ion battery is an excellent performance, can be widely used in aviation, aerospace and other structure in the field of energy. Miniature Unmanned Aerial Vehicle (MAV), the paper profiled polymer lithium ion battery used for the study, positive and negative ratio, laminations way through the systematic study of its molding process, packaging process, and by design, the choice of the high energy density binary cathode material, anode material modification method, prepared to meet the requirements of MAV profiled polymer lithium ion battery samples. The thesis of the size of a particular complex shape shaped polymer lithium ion preparation process. Temperature, time, pressure, and other factors to determine the positive better composite process: temperature 140 ℃, pressure 2MPa, the time 30S; negative better composite process: temperature 150 ℃, pressure 2MPa, time 30S. To heated profiled battery even by force, using the molding method of hydraulic soft film battery was fabricated, by the study of the different thickness of the silicone rubber membrane, composite temperature, time, pressure and other factors, it is determined the battery is first pre-pressure molding, and then the composite Forming the preparation process. The pre-pressure molding allows the battery to the basic shape, and make up the the profiled composite mold pressure uneven. The experiments show that the preload molding and forming composite conditions are: temperature 100 ° C, pressure 1MPa, time 5min. The mold the ABNORMAL package in order to meet the need of the battery package, design and prepare a battery, using the mold greater curvature of the profiled edge package, the package shaped battery to maintain a good aerodynamic shape, meet the MAV's request. The experiments show that better packaging process: voltage 12V, time 20S. Using the same raw materials, profiled battery and the flat battery was prepared, and the electrical properties of the battery and the flat battery of tests show profiled have similar energy density, cycle efficiency and resistance, indicating that the preparation process of the profiled polymer lithium ion batteries feasible. Profiled battery energy density of the battery positive and negative electrode material ratio, laminations manner, and uses a binary higher capacity cathode material prepared shaped battery, the first discharge energy density 169wh/kg . The method to prepare a modified negative electrode material, considering the influence of tin content on the reversible capacity, cycle efficiency, its preferred tin content is determined at 20%, the reversible capacity of the negative electrode material in the modified 20% increase of the sodium borohydride reduction of the tinned or so.
