Lithium ion battery charging have any impact on battery performance? What are the possible reasons for battery discharge time is short? Different capacity of lithium battery together use will appear what problem? The basic characteristic of the lithium ion battery and security features have those?

A, different capacity of battery together use will appear what problem?

If the different capacity or use old and new batteries together, possible discharge, the phenomenon such as zero voltage. This is because in the process of charging, charging capacity differences lead to some battery overcharge, some of the battery is not full of electricity, high capacity of the battery discharge power, not put up the low capacity is put. A vicious cycle, cell damage and leakage and low pressure (zero) to produce safe hidden trouble.

Second, the basic properties of the lithium ion battery?

1, high energy density, lithium ion battery is the weight of the same capacity of half of the nickel cadmium or nickel metal hydride batteries, volume is 20-30% of nickel cadmium, nickel metal hydride 40-50%.

2, high voltage, a lithium ion battery monomer working voltage of 3.7 V (mean), the equivalent of three series of nickel cadmium or nickel metal hydride batteries.

3, no pollution (environmental protection), lithium ion battery does not contain heavy metals such as cadmium, lead and mercury.

Three, lithium battery is stored in what kind of condition is better?

According to the IEC standard, should think lithium battery in the temperature of the battery is 20 + / - 5 ℃, humidity for RH (20) 65 + % under the conditions of storage. In general, the higher the storage temperature, your battery capacity of residual rate is lower. On the other hand, too. The refrigerator temperature during 0 to 10 ℃ storage battery the best place. Especially the more strict with the battery, and the secondary battery even lost after storage capacity, but as long as to charge and discharge capacity can be recovered after a few times.

Four, short battery of battery discharge time what are the possible reasons?

1, the battery is not full of electricity, such as charging time is not enough, charging efficiency is low;

2, the discharge current is too large, the discharge efficiency so that the discharge time shorten;

3, the battery discharge when the environment temperature is too low, the discharge efficiency decreases.

5, what is the charge have any impact on battery performance?

Charging is refers to the battery charge through a certain process, continue to charge behavior, such as Ni - Cd battery, charging respond as follows: the positive: oh - 4 e2h2o + O2 cathode: 2 Cd + O22CdO because, in the design of the cathode capacity higher than the positive capacity. Oxygen through the diaphragm paper as a result, the anode and cathode produce cadmium composite. So in general, the battery should be fully avoid charging situation, China‘s battery net suggest lithium-ion battery pack needs to be combined with protection board, and battery protection board should have overcharge, discharge function.

Six, lithium ion battery safety features?

Lithium ion battery has very wide application in People‘s Daily life, so it should be absolutely safe performance of lithium ion battery first assessment indicators. For lithium ion battery safety performance evaluation indexes, the international rules on the very strict standards, lithium ion battery there are no fatal flaws in security performance.
