The lithium-ion battery is a rechargeable battery that relies mainly on lithium ions to move between the positive and negative electrodes. During the charge and discharge process, Li + is embedded and deserted between the two electrodes: When the charging cell, Li + is escaled from the positive electrode, and the electrolyte is embedded in the negative electrode, the negative electrode is in a lithium state; the discharge is reverse. Generally, a battery containing lithium element as an electrode is a representative of modern high performance cells.The lithium battery is divided into a lithium battery and a lithium ion battery. The mobile phones and laptops are used by lithium-ion batteries, usually people are commonly known as lithium batteries, while real lithium batteries are rarely applied to daily electronic products due to their dangerous.
Lithium ion batteries are generally negative in graphite carbon material.
Li-Ion Batteries is the development of lithium batteries. So before introducing Li-ION, first introduce lithium batteries. For example, the buckle battery used in the previous camera belongs to a lithium battery. The positive electrode material of the lithium battery is manganese dioxide or thionyl chloride, and the negative electrode is lithium. The battery is not charged after the battery is completed. Such a battery can also be charged, but the cycle performance is not good, and lithium crystals are easily formed during the charge and discharge cycle, resulting in short circuit inside the battery, so that this battery is forbidden to charge.
Carbon material lithium battery
Later, Sony, Japan invented the lithium battery with a carbon material as a negative electrode, and a lithium battery with a lithium-containing compound, during charge and discharge, only lithium ions, which is a lithium ion battery.
Rock chair battery
The battery capacity we usually refer to the discharge capacity. During the charge and discharge of Li-ION, the lithium ion is in a motion state from the positive electrode → negative electrode → positive electrode. Li-Ion Batteries is like a rocking chair, the two ends of the rocking chair are the two poles of the battery, and the lithium ions run back in the rocking chair as athletes. So Li-Ion Batteries is also called a rocking chair.

Main type
Depending on the electrolyte material used in the lithium ion battery, the lithium ion battery is divided into a liquid lithium ion battery (Liquified Lithium-Ion Battery, referred to as LiB) and polymer lithium ion battery (PLB).
Lithium ion battery (Li - ION)
Rechargeable lithium-ion battery is currently available in modern digital products such as mobile phones, laptops, but it is more "delicate", which is not supercharged in use, and it will damage the battery or scrapped. Therefore, there is a protective element or protection circuit on the battery to prevent expensive battery damage. Lithium-ion battery charging requirements are high, to ensure that termination voltage accuracy is ± 1%, major semiconductor devices factory has developed a variety of lithium-ion batteries charged ICs to ensure safety, reliably and quickly charge.
The phone is basically used using a lithium ion battery. It is important to correctly use lithium-ion batteries to extend battery life. It can make flat long squares, cylindrical, rectangular and buckle according to different electronic products, and there are battery packs composed of several batteries in series. The rated voltage of the lithium ion battery, because the material changes, typically 3.7V, lithium iron phosphate (hereinafter referred to as the phosphate) positive electrode is 3.2V. The termination charging voltage at full charge is generally 4.2V, phosphate 3.65V. The termination discharge voltage of the lithium-ion battery is 2.75V ~ 3.0V (the battery plant gives the operating voltage range or gives the termination discharge voltage, each parameter is slightly different, typically 3.0V, phosphate is 2.5V). Currently less than 2.5V (phosphate 2.0V) Continue to discharge is called over, and the overlays will be damaged.
The lithium-cobalt type material is not suitable for use as a large current discharge, and excessive current discharge will reduce the discharge time (the inside will produce a higher temperature and loss energy), and the lithium iron phosphate The positive electrode material lithium battery can be charged and discharge at a large current of 20c or even greater (C is the capacity of the battery, such as C = 800 mAh, 1C charging rate, and a charging current of 800 mA), is particularly suitable for electric vehicle use. Therefore, the battery production plant gives a large discharge current, which should be smaller than the large discharge current. Lithium-ion batteries have certain requirements for temperature, and the plant gives the charging temperature range, the discharge temperature range and the storage temperature range, and overprust charge can cause the lithium ion battery to be permanently damaged. Lithium-ion battery charging current should be based on the suggestion of the battery production plant and require a limited flow circuit to avoid overcurrent (overheating). Generally commonly used charging magnification is 0.25c to 1c. The battery temperature is often detected when the large current is charged to prevent overheating damage to the battery or an explosion.
