The difference between a lithium-ion battery and a lithium battery

Introduction The difference between lithium-ion batteries and lithium batteries is their working principle and their ability to be charged. Lithium batteries, including lithium metal batteries and lithium ion batteries, are a type of lithium metal or lithium alloy neg

The difference between a lithium-ion battery and a lithium battery

The difference lies in the principle of operation and the possibility of charging it. Lithium batteries, including lithium metal batteries and lithium ion batteries, are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. However, strictly speaking, lithium batteries refer to lithium disulfuryl chloride batteries, which are primary batteries and can only be discharged but not recharged. They can only be recycled once used up.

Lithium-ion batteries are a common type of battery in daily life. Batteries in mobile phones, tablets and electric cars are secondary batteries and can be recharged and used repeatedly. The main characteristic of a lithium-ion battery is that its negative electrode is made of materialsintercalated structural materials such as graphite. In the battery, lithium ions move between the positive and negative electrodes, which is much safer than lithium batteries.

What is the difference between lithium batteries and lithium-ion batteries? What are their respective characteristics?

The chemical reactions are different, the energy density is different, and the charging and discharging performance is different.

1. Different chemical reactions: Ion battery is a broad concept, including different types of batteries, such as lithium-ion batteries, nickel-metal hydride batteries, etc. Lithium batteries are a specific type of ion battery whose positive electrode material is mainly composed of lithium compounds, such as lithium iron phosphate, lithium cobaltate, etc. Lithium batteries are a subcategoryionic batteries.

2. Different energy density: Lithium batteries have a higher energy density and can store more energy in the same volume or weight. This makes lithium batteries widely used in areas such as portable devices and electric vehicles. Other types of ion batteries, such as nickel-metal hydride batteries, have relatively low energy density.

3. Different charging and discharging properties: Lithium batteries have good charging and discharging properties and can be charged and discharged multiple times without significant capacity loss. Other types of ionic batteries have a memory effect or self-discharge phenomenon, which results in faster loss of capacity or more frequent charging.

Lithium batteries and lithium ion batteries (lithium ion polymer batteries), lithium batteries are a type of materialof lithium metal or lithium alloy negative electrode due to the highly active chemical properties of. lithium metal, lithium The processing, conservation and use of metals have very high environmental requirements. The negative electrode of lithium-ion batteries is made of intercalated structural materials such as graphite. In the battery, lithium ions move between the positive and negative electrodes, making it much safer than lithium batteries. Lithium-ion batteries and lithium-polymer batteries, the electrolyte of lithium-ion batteries is liquid, while the electrolyte of polymer batteries is gel or solid, which is safer. The packaging of lithium polymer battery cases and lithium batteries is slightly different. Lithium batteries are usually packaged in steel cases (18650 or 2320 button type), while lithium polymer batteries are packagedin aluminum plastic packaging films, i.e. flexible batteries. Lithium batteries are divided into liquid lithium batteries and lithium polymer batteries. Lithium polymer battery is an improved product of lithium ion battery. Compared with currently popular lithium-ion batteries, it has the advantages of large capacity, small size (thin) and safety (will not explode).
