Solid polymer electrolyte lithium ion battery. The electrolyte is a mixture of polymer and salt. This battery has low ionic conductivity at room temperature and is suitable for high temperature use.

In terms of improving the room temperature ionic conductivity of gel polymer electrolyte and enhancing its mechanical strength, composite gel polymer electrolyte is undoubtedly a good choice. In compo

Electrolyte is an ionic conductor for conducting between the positive and negative electrodes of lithium-ion batteries.

In terms of the voltage of each unit cell, nickel hydrogen is 1.2V, while lithium-ion battery is 3.6V, and the voltage of lithium-ion battery is 3 times.

The active balance abandons the passive balance method of consuming current and changes to the method of transmitting current.

The discharge termination voltage of lithium-ion battery is an important application parameter related to the service life of lithium-ion battery.

For the sake of safety, the cathode material should have good compatibility and stability with the electrolyte.

The gravure roller coating process is a commonly used coating method at present. The micro gravure roller takes the slurry out of the slurry box, scrapes off the excess coating with a constant thickne

First, the potential of the material itself is high, so that a large potential difference can be formed between the material and the negative electrode material, resulting in a high energy density cel

The positive electrode material is an important source of lithium-ion batteries. When the lithium-ion batteries are separated from the positive electrode, in order to maintain the electrical neutral s

These two types of chargers cannot be mixed, or the battery will be directly scrapped. Because the charging modes of the lithium battery charger and the lead-acid battery charger are different.

Energy density: at present, the energy density of lead-acid batteries is about 5070wh / g, while the energy density of lithium-ion batteries is generally 200260wh / g.
