Capaches with 2V300ahgel colloidal battery cost accounting and priceHuizhong high energy battery introduction
1 Magnesium dry high energy cells with magnesium as negative electrode active substances: The structure is substantially the same as zinc-manganese dry batteries. The standard electrode potential of magnesium is relatively low, and the electrochemical equivalent is small, and there is excellent conditions for high energy battery negative active substances. For example, the actual amount of magnesium-manganese dry battery is 4 times the zinc-manganese dry battery, and the voltage is stable in operation, and there is a good working ability at low temperatures, and can be stored with high temperature. The disadvantage is that there is a voltage lag (after the connection is required, the voltage can rise to the termination voltage value), the lag time is about 2 ~ 3 seconds; the magnesium electrode current is low; not suitable for small current long time Intermittent discharge.

2 Metal-Air High Energy Battery: Oxygen in the air as a positive electrode active material, metal as a negative electrode active material.

3 lithium-nonaqueous electrolyte solution High energy cells: lithium electrochemical equivalents is about one-half of magnesium, so as the negative electrode of high energy cells, lithium is more preferable than magnesium. However, lithium is intensely reacted with water, and the electrolyte solution is required to be formulated with an organic solvent or a non-water inorganic solvent to add inorganic salts. The positive electrode material used is mainly solid fluoride, chloride, oxide, sulfide. These batteries are mostly more energy to 1000 watts / kg. Its actual is relatively high. For example, lithium-fluorinated copper (Li / Cuf2) battery When the discharge current density is 2 mA / cm 2, the actual amount of energy can reach 250 watts / kg. Since the specific electrolyte solution is small, the current density cannot be improved, so the lithium-nonaqueous electrolyte solution is a high-proportioned energy, low-power battery. Lithium-sulfide batteries are discharged under heavy load, especially when the external is short-circuited.

4 sodium-sulfur high cells: It is a relatively mature second high energy battery developed in recent years. Its negative electrode is molten metal sodium (Na); the positive electrode active material is molten polyulfide (Na2Sx), usually filled with carbon, carbon as a positive electrode current collector. The electrically conductive ceramic tube needs to be separated from sodium sodium sulfide to prevent self-discharge by direct reactions. In addition, the ceramic tube also causes the electrolyte effect in the battery. When the battery is discharged, the reaction on the negative electrode is 2NA- → 2NA ++ 2e-Na +

The positive electrode and the sulfur were formed by the conductive ceramic tube to form a polysulfide. When the sodium of the negative electrode is exhausted, the discharge is terminated. In order to make sodium and polyulfide are in liquid, the discharge needs to be carried out at around 300 ° C. The actual ratio of sodium-sulfur cells has reached 100 watts / kg, and the charge and discharge cycle life can reach 2000 deep discharge cycles, and therefore is particularly suitable for use as a vehicle’s electric battery.
