The current is too high. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The first lithium battery came from the great inventor Edison. The reason why the voltage is high and the discharge is high. high is due to the current being too high. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements.
Normally, the fully charged lithium iron phosphate battery cell is 3.2V. Although it is resistant to overcharging, charging at a higher voltage will still damage the battery.
Charging voltage increases as battery power increases. In order to guarantee a constant charging current, the segmented charger continuously increasesGenerally the battery charging voltage is 60*1.2=72V.
The charging voltage should be set to 3.65V, the rated voltage is 3.2V. Generally , the maximum charging voltage can be 20% higher than the rated voltage, but too high voltage can easily damage the battery. The voltage of 3.6 V is lower than these indicators, no overload.
If the battery needs to be charged if the minimum setting is 3.0 V, then 3.4 V is 0.4 V higher than the lowest, and 3.6 is 0.6 V higher than the lowest lower. The extra 0.2V can free up half. of power, which means that each time, charging takes half as long as 3.4 V. Since the battery is used a certain number of times, the lifespan is increased by half. Therefore, increasing the charging voltage without damaging the battery will increase the battery. life.
Detailed information:
The limit ofe 3.6V charging for lithium iron phosphate and other battery designs should be From the practical application of lithium batteries, the battery capacity can be fully activated to the maximum without damaging the battery. The charge number refers to the number of complete charge and discharge cycles, although the 3.4V design does not do this. Due to overload, there will be a small part that will not participate in the cycle. After charging and discharging, most participants will still experience performance deterioration as the number of cycles increases up to a certain number, leading to a vicious cycle until they are. are no longer usable.
This is due to its service life limit, the superposition of various unavoidable harmful and unfavorable factors, and the performance is inevitably unable to maintain the original design parameters.
TheRechargeable lithium batteries have been widely used. Lithium iron phosphate batteries are increasingly used due to their unique advantages. The charger for lithium iron phosphate batteries is different from ordinary lithium batteries. The maximum end-of-charge voltage is. 4.2 volts.
The lithium iron phosphate battery is 3.65 volts (some people on the internet say the maximum cannot be higher than 3.8 volts. Now the question is: a phone charger portable (with a slight modification) can it be). used for lithium iron phosphate? Charging the batteries; or use of discarded (slightly modified) lithium battery protection circuit boards for charge protection of lithium iron phosphate batteries.
