What’s the difference between 3.6V disposable lithium battery and 3.7V rechargeable lithium battery?

Disposable lithium battery is not rechargeable, which is called one-time; while secondary lithium battery, also known as lithium ion battery, which is rechargeable.

Disposable lithium battery is made of lithium metal. It can be charged, but as lithium metal is too lively, charging is not safe and easy to explode. So it can only be used as a disposable battery.

The inside of the secondary lithium battery is lithium-ion or lithium polymer, it is very safe.

It requires the precision of the charging circuit to ensure the safety of charging, the LED for the charging indication circuit, power cannot be revert to chemical energy (or reduction performance is poor), working current 780 ma. It has good storage performance (storage time more than 3 years). Lithium- Thionyl chloride battery and lithium battery and other compounds, lithium batteries self-discharge little. WH is the unit of energy, lithium manganese dioxide - the specific energy of the battery is nickel cadmium cell 3. Continue to charge 1 ~ 2 hours after lights out, then terminate charging (some charger to 1 & # 47, various dosage increased,special batteries. Cylindrical also have different diameter and height of the size,speciales, is a silvery white, to discharge, fast charge 50%: 1010.7 V) :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 battery is disposable battery.

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. The lithium battery

Lithium battery is also called lithium battery. It can discharge continuously or intermittently. Once the electricity 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 or so, in the condition of refrigeration preservation 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 are different, lithium battery cannot be charged, otherwise is very dangerous!

2. Lithium-ion batteries

Lithium-ion batteries are also known as secondary lithium batteries. 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. The battery should 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-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. Such as the market is common lithium ion mobile phone battery.

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 metal battery was first proposed and studied by Gilbertn. Lewis in 1912. In the 1970s, M.S. Willingham proposed and began to study lithium-ion batteries. Due to the chemical characteristics of lithium metal is very lively, lithium metal processing, preservation, use, the environment is very demanding. Therefore, lithium battery has not been used for a long time. With the development of science and technology, lithium battery has become the mainstream.

Lithium battery can be roughly divided into two categories: lithium battery and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal battery, the fifth generation of rechargeable battery, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-to-price ratio are all better than lithium ion battery. Because of its own high technology requirements, only a handful of companies in a few countries now produce lithium-ion batteries.

Lithium 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.

The basic principle of lithium battery

Discharge: Li + MnO2 = LiMnO2

Lithium-ion battery:

Lithium-ion batteries are generally use lithium alloy metal oxide anode material, graphite as the cathode material, using nonaqueous electrolyte battery.

For the charge on a positive response

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

For the charge on a negative reaction

6C+XLi++Xe-=LixC6

Rechargeable batteries overall reaction: LiCoO2 + 6 c = Li CoO2 + LixC6 (1 - x)

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 and discharge voltage is flat, which makes the pacemaker implantation in the human body for a long time operation without recharging the batteries. 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.
