What is the difference between 3.6v disposable lithium battery and 3.7v rechargeable lithium battery

A lithium battery, is not rechargeable, one-time, and secondary lithium battery also known as lithium ion battery, is rechargeable cycle

The lithium in secondary lithium batteries is lithium ion or lithium polymer, which is very safe.

It requires a precise charging circuit to ensure the safety of charging, LED as the charging indicator circuit, cannot restore electrical energy to chemical energy (or poor reduction performance), working current 780 milli-ampere; Good storage performance (storage time of more than 3 years), as shown in figure 1, lithium-thionyl chloride battery and lithium and other compound battery, lithium battery self-discharge small. Wh is a unit of energy, so the specific energy of lithium-manganese dioxide battery is 3 of nickel-cadmium battery. Please continue charging for 1-2 hours after the indicator light is off, and the charging can be stopped (some chargers reach 1/, the amount of various batteries increases greatly, and thespecial. Cylindrical also have different diameter and height size,special, is a silver-white, to be maintained at 50% discharge state, quick charge: 1010.7v) : time T terminal voltage V.

Lithium battery is lithium metal as an electrode, with electron transfer to generate current, because easy to produce dendrites cause explosion, so it has long been out of use. Lithium batteries are primary batteries.

Lithium ion battery is the transfer of lithium ions to complete the charge and discharge, mainly lithium doped metal oxide as the electrode. Lithium-ion batteries are rechargeable secondary batteries.

1. Lithium battery

It also called a lithium battery. It can discharge continuously or intermittently. Once the power is used up, it can no longer be used. It is widely used in low-power electronic products such as cameras. Lithium battery self-discharge is very low, can be stored for 3 years, in the condition of refrigeration preservation, the effect will be better. It is a good idea to store the lithium battery in a low temperature place. Note: lithium battery and lithium ion battery is different, lithium battery can not be charged, charging is very dangerous!

2.Lithium-ion batteries

It is also known as secondary lithium battery. Under the 20 ℃ can be stored for more than six months, it is because of its low self-discharge rate, and most of capacity can be restored.

Self-discharge phenomenon exists in lithium battery. If the battery voltage is kept under 3.6v for a long time, it will lead to over-discharge of the battery and damage the internal structure of the battery, thus reducing the battery life. Therefore, long-term lithium battery should be recharged every 3 to 6 months, that is, the charging voltage is 3.8-3.9v (lithium battery optimal storage voltage is 3.85v or so), keep at 40-60% discharge depth is appropriate, not full. Batteries are to be kept at 4 ℃ ~ 35 ℃ or moisture-proof packaging in dry environment. Keep away from heat sources and from direct sunlight.

Lithium batteries are used in a wide range of temperatures. They can still be used outdoors in the winter in the north, but their capacity will decrease a lot. If they return to room temperature, their capacity can be restored.

It isn't.

Lithium battery is a kind of battery which is made of lithium metal or lithium alloy as negative electrode material and USES non-aqueous electrolyte solution.

Lithium battery can be roughly divided into two categories: lithium metal battery and lithium ion battery. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal battery is a disposable battery, cannot be charged.

Lithium batteries fall into two categories: non-rechargeable and rechargeable. Non-rechargeable batteries are called disposable batteries, which can only convert chemical energy into electrical energy once and for all, and cannot restore electrical energy to chemical energy, such as lithium - manganese dioxide primary battery, lithium - thionyl chloride primary battery. Rechargeable batteries are called secondary batteries. It can change electric energy into chemical energy to store, when using, change chemical energy into electric energy again, it is reversible, be like the lithium ion mobile phone battery on the market commonly.

Lithium metal battery:

Lithium metal battery is generally the use of manganese dioxide as a positive electrode material, lithium metal or its alloy metal as a negative electrode material, the use of non-aqueous electrolyte solution of the battery.

Basic principle of lithium battery

Basic principle of lithium battery

Discharge reaction: Li+MnO2=LiMnO2

Lithium ion battery:

Lithium ion battery is generally the use of lithium alloy metal oxide as a positive electrode material, graphite as a negative electrode material, the use of non-aqueous electrolyte battery.

The reaction on the positive electrode of charge is

LiCoO2 = = Li (1 -) x CoO2 + XLi++ Xe - (electronic)

The reaction on the negative electrode of charge is

6 c + XLi++ Xe - = LixC6

Total rechargeable battery reaction: LiCoO2+6C=Li(1-x)CoO2+LixC6

The anode

Anode material: many cathode materials are available, and lithium iron phosphate is widely used in mainstream products. Comparison of different anode materials:

Lithium batteries were first used in pacemakers. Lithium battery self-discharge rate is very low, discharge voltage gentle advantages, so that the implanted pacemaker can operate for a long time without recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts, more suitable for integrated circuit power supply. Manganese dioxide batteries are widely used in calculators, digital cameras and watches.

In order to develop better performance varieties, various materials have been studied to produce unprecedented products.

In 1992, Sony successfully developed lithium-ion batteries. Its practicality has greatly reduced the weight and volume of portable electronic devices such as mobile phones, laptops and calculators.
