First Grade pole pieces impregnate five component colloidal sols in it is compound, gel permeation is proposed in graphite felt hole from microwave mixer compound
Good graphite felt spontaneously dries 2 days, is sent into after drying in microwave agglomerating furnace and is calcined 2h at 600 DEG C, after with 2 DEG C/min of speed liters
1200 DEG C of roasting 2h are warming up to when temperature is to 1054 DEG C, after constant temperature 1H with 2 DEG C/min of speed again, and Na β "-Al is made2O3Ceramic membrane,
Then normal temperature is naturally cooled to, vacuum saves backup after coming out of the stove；
（3）Sodium chlorine medium temperature switch-board thermoelectric pond encapsulates, by positive/negative plate by monomer voltage and Capacity design requirement positive/negative plate
Intersection stacks, and after being fastened with aramid fiber, both positive and negative polarity collector bar is welded, by polyimides/aromatic diacid acid anhydride/
Aromatic diamines press 1：1：The mass ratio of 1 molar ratio addition low boiling methanol solution, methanol solvate and mixture is 1：1, micro-
In Wave heating mixer, 450 DEG C of constant temperature are heated to by 5 DEG C/min of speed, fill polyimides/aromatic diacid acid anhydride/aromatic diamines
Divide dissolving polymerization, obtaining Thermocurable polyimide solution turns into the premix encapsulated, and the cell fixed is put into premix
Taken out after impregnating 5s in material, then natural cooling is standby；
（4）Battery case encapsulates, and selects, with 1mm thickness stainless steel plate materials, container of different sizes to be made up of punching press, interior
Layer container and outer layer container facade distance 20mm, lower plane distance 10mm, upper plan range 20-50mm, internal layer iron-holder 50%
Stainless steel, with CaO, SiO2, ethanol in molar ratio 1：1：2 are mixed evenly clay are made, then clay is painted in
Wound clockwise diameter 1-2.5mm copper binding wires, then application 10mmCaO, SiO are pressed after the 10mm of layer outside2Ethanol clay, it is sent into drying
Room is dried, and wire circle and diameter are prepared by design power, then by two layers by stainless steel welder into hollow, be embedded in
CaO、SiO2The hollow cell shell of alcohol mixture and U-shaped stainless steel parting bead, battery core is loaded in hollow cell shell, will
PTC300 DEG C of temperature switch and temp probe are arranged on battery core medium position, and are connected with control panel, then by each list of battery
