Lithium battery.
Since the lead acid battery contains electrolyte, it is not very useful in cold winter weather and the stored power will decrease. It's easy to run out of energy or cause loss. of power, making it difficult or impossible to start the car. However, relatively speaking, lithium batteries have greater adaptability to high and low temperatures, are less affected by temperature factors, and are more durable in winter. However, all batteries are prone to power loss in low temperature environments and are not as durable as in summer, but lithium batteries lose less power.
Precautions for using lithium batteries
To charge lithium-ion batteries, a dedicated lithium-ion battery charger should be used. Lithium-ion battery charging adopts CC/C methodV (. constant current + constant current). (Voltage) That is, charge with constant current first, then switch to constant voltage charging when the voltage reaches 4.2V*n, and stop charging when the current decreases to 0.01 C.
Lithium-ion batteries can be stored in a clean, dry, ventilated room with an ambient temperature of -5°C to 35°C and relative humidity not exceeding 75%. should be avoided and kept away from fire source and heat source. The battery power remains between 30 and 50% of the nominal capacity. It is recommended to recharge stored batteries every 6 months.
The suitable operating temperature of lithium polymer batteries is normal temperature (25 degrees Celsius ± 5), and the theoretical operating temperature is -40 to 70 degrees Celsius. The storage temperature complies with the theoretical use temperature (-40 to 70 degrees Celsius).
LLithium polymer batteries use lime alloy as the positive electrode of the battery, polymer conductive materials, polyacetylene, polyaniline or polyparaphenol as the negative electrode of the battery, and the electrolyte uses organic solvents. The temperature limit of lithium polymer batteries is that because the electrolyte is made of colloidal material, no gas will be generated from inside the battery under high temperature conditions, thereby improving the safety of the battery .
Detailed informationLithium polymer batteries have the following characteristics and advantages:
1. Lithium polymer batteries have extremely high plasticity and can be made into thin batteries (the minimum thickness can be as thin as possible). such as 0.5mm), can also be made into batteries of different shapes, greatly improving the portability ofe the user.
2. The storage capacity of lithium polymer batteries has been significantly improved compared to previous lithium batteries. Theoretical data obtained from the production process shows that the storage capacity of lithium polymer batteries is 10% higher than that of lithium polymer batteries. ordinary lithium-ion batteries.
