A kind of nano silicon colloid battery

Abstract

The invention belongs to a nano-silica colloid storage battery; it includes a shell, and the inside of the shell includes several grids with a radial arc corrugated structure and a colloidal electrolyte. The grids with a radial arc corrugated structure include a frame, and the top of the frame is arranged There are pole ears, and the inside of the frame is provided with circular arc corrugated horizontal ribs and radial vertical vertical ribs; the cross section of the frame is a hexagonal structure with short and equal upper and lower sides, and the remaining sides are long and equal. The width is equal to 75% to 85% of the length; the tab is set at 1 / 2-(7-12) mm of the total width of the top frame, between the height of the lower part of the arc-shaped tab connection and the height of the top of the side frame The difference is 1-3mm; the weight of the grid does not increase, and the paste amount of the active material is not reduced, which can solve the muddying of the active material during the repeated charge and discharge process of the battery. The overall weight of the battery is light, the temperature adaptability is wide, and it is resistant to vibration. It is resistant to heat and humidity and can significantly improve the cycle life of the battery.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to a nano-silica gel accumulator. Background technique [0002] Generally, the limit of the operating temperature range of lead-acid batteries is -18°C to 40°C, and some standards are even lower. my country's colloidal battery adopts the communication industry standard, YD / T1360-2005, its normal working environment temperature is 20 ℃ ~ 30 ℃, and the lowest detection temperature is only -18 ℃. However, at present, very few batteries produced at home and abroad can meet the above standards; in addition, ordinary lead-acid batteries use liquid dilute sulfuric acid as the electrolyte, and the sulfuric acid mist is relatively large during work, polluting the environment, and causing serious damage to the physical and mental health of producers and users. Huge damage has come, and there is a risk of leakage; in order to overcome the above defects, most manufacturers use...

AI Technical Summary

Problems solved by technology

An important phenomenon was found after dissecting and dissecting the failed battery. The lead paste mud was concentrated in the tabs and the lower 3 / 1 position. The grid is the current collector of the active material of the battery plate. The current derived from each grid node at the lower part of the grid is only 1% to 0.3% of the current derived from the grid node near the tab (varies with the area of ​​the grid). The larger the grid area, the smaller the current derived from the lower grid node of the grid, and the grid node current near the tab is the collection of the lower grid node current, so the current of the grid node near the tab is The grid node current at the lower part of the grid is more than 100 times, resulting in the accumulation of grid current near the tabs, and serious heating and deformation
