Introduces some basic concepts of lithium battery

Source: 2020 - 04 - 11 after clicks: first lithium batteries of some basic concepts in terms of energy, and other forms of energy directly into direct current device is often referred to as the battery. Whether according to the reusable is divided into a battery and a secondary battery. Don't charge the battery as a battery; Rechargeable battery is called the secondary battery. The exact meaning of the secondary battery: use the chemical reaction is reversible, you can build into a new battery, that is to say, when a chemical reaction into electrical energy, you can also use electricity to repair the chemical system, and then converted to electrical energy in a chemical reaction, the characteristics of the battery is called the secondary battery. Generally refers to the secondary battery cells activated by means of charge after discharge. Lithium battery refers to the electrochemical system contains lithium ( Metal lithium, lithium metal and lithium ion, lithium polymer) The basic electrochemical unit. Lithium battery can be roughly divided into three broad categories: lithium batteries, lithium ion battery and lithium ion polymer battery. 1) Lithium battery: strictly speaking, lithium battery, Lithium battery) Contain pure lithium metal. Manganese dioxide as the commonly used lithium battery cathode materials, anode materials for lithium metal or its alloy metal, using nonaqueous electrolyte solution. Disposable, used in the cell. Lithium ion battery is not including metallic state lithium secondary battery. Lithium ion batteries commonly used lithium alloy metal oxide as the anode material, graphite as the cathode material, using nonaqueous electrolyte battery. It mainly rely on lithium ion move to move between the positive and negative electric charge, so as to generate an electric current. ( 3) Lithium-ion polymer battery: is a kind of colloid or solid polymer instead of liquid organic solvent of secondary lithium ion battery, with better security. Also known as' lithium polymer batteries. Traditionally, the secondary lithium ion battery is referred to as lithium ion battery, lithium ion battery is referred to as lithium batteries.
