Do you know the basic concept of lithium batteries?

From an energy point of view, a device that converts other forms of energy directly into DC power is commonly known as a battery. Battery press can be reused can be divided into primary and secondary batteries. Non-rechargeable batteries are called primary batteries; The rechargeable battery is called a secondary battery. The exact definition of a secondary battery: Using the reversibility of a chemical reaction, a new battery can be constructed, that is, when a chemical reaction is converted into electrical energy, it can also be used to repair the chemical system and then use the chemical reaction to convert it into electrical energy. Batteries with the above characteristics are called secondary batteries. In a nutshell, a secondary battery is a battery that can continue to be used after the battery is discharged by recharging the active substance.

Lithium Cell refers to the most basic electrochemical unit containing Lithium(metallic lithium, lithium alloy, lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into three categories: lithium metal batteries, lithium-ion batteries, and lithium-ion polymer batteries.

(1) Lithium battery: The strict lithium battery is a lithium primary battery(lithium metal battery) containing a pure lithium metal. Lithium primary batteries generally use manganese dioxide as a positive electrode material, lithium metal or its alloy metal as a negative electrode material, and batteries using non-aqueous electrolyte solutions. One-time use for a battery.

(2) Li-ion batteries are secondary batteries that do not contain metallic lithium. Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and batteries using non-aqueous electrolytes. It mainly relies on lithium ions to transfer charges between positive and negative poles to form currents.

(3) Lithium-polymer batteries: A secondary lithium ion battery that replaces liquid organic solvents with colloidal or solid polymers and has better safety. Also known as "lithium polymer batteries."

It is customary to refer to a secondary lithium ion battery as a lithium ion battery, and a lithium ion battery is also referred to as a lithium battery.
