Problems solved by technology

[0002]At present, the low-temperature performance of lead-acid batteries used in electric mopeds is not good, and generally can only meet or slightly exceed the national standard: the low-temperature capacity at -15°C reaches 0.7C 2, and at present, domestic batteries with better low-temperature performance can reach: -20°C low-temperature capacity of 0.75C2; but their charging and receiving performance is relatively poor, generally only Slightly exceeds the national standard value: Ica/I0≥2 (Ica is the charging current, I0 is the discharge current: 0.1C2) , generally can reach: 2.0~2.3
It cannot meet the requirements of low temperature environment below -20°C, especially in the northeast and northwestern regions of our country, some of which can reach -30°C in winter
Therefore, in the cold northern regions of our country, there are common phenomena

Embodiment 1

[0048] Example 1 Preparation of expansion agent

[0049] (1) Add 12.0L of sulfuric acid into the lead bucket (density at 15°C is 1.40±0.05g / cm 3 ), the lead skin barrel is heated by steam.

[0050] (2) Open the valve of the heating steam on the lead drum, and when the sulfuric acid is heated to 80°C, adjust the steam valve to keep the temperature of the sulfuric acid between 80°C and 100°C.

[0051] (3) Put 3.0Kg of cotton (pure seedless cotton) into the lead bucket within 10 minutes, and at the same time, keep stirring with a plastic rod until all the cotton is semi-carbonized into a yellow-brown slurry (it cannot be carbonized and blackened) , close the steam valve.

[0052] (4) The expansion agent can only be used when the temperature drops to no higher than room temperature by 5°C. The storage period of the prepared expansion agent shall not exceed 3 days.
