Lithium ion battery: It is a type of battery that uses materials that can undergo lithium ion insertion/extraction reactions as positive and negative electrode active materials, and uses organic electrolytes or polymer electrolytes containing lithium salts. It is a secondary battery (i.e. rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to function.
Ferrous lithium phosphate: It is an electrode material for lithium-ion batteries, with the chemical formula LiFePO4 (LFP). It has the advantages of high energy density, high safety, and long lifespan.
All solid state rechargeable Li ion battery: As the name suggests, it refers to a lithium-ion battery in which the electrodes (positive and negative electrodes) and electrolyte are both in solid state. This type of battery consists of three parts: positive electrode material, solid electrolyte, and negative electrode material, and does not contain any liquid components. The positive electrode is usually made of lithium metal or lithium-ion compounds, while the negative electrode is made of carbon materials or lithium titanate salts. Solid electrolytes are composed of inorganic solid materials such as oxides, sulfides, or phosphates.
Gel polymer rechargeable Li ion battery: it is a kind of lithium ion battery that uses gel polymer electrolyte as the ion conduction medium. This type of battery is structurally similar to liquid lithium-ion batteries, but the main difference lies in the electrolyte. Gel polymer electrolyte is composed of a mixture of polymer and salt, and may add plasticizers and other additives to improve ionic conductivity. The electrolyte can be "dry" or "colloidal", most of which are polymer gel electrolytes.
Half solid state Li ion battery: refers to a battery in which one electrode does not contain liquid electrolyte and the other electrode contains liquid electrolyte, or where the mass or volume of solid electrolyte in a single cell accounts for half of the total mass or volume of electrolyte in the cell. This type of battery combines some of the characteristics of liquid and solid-state batteries, retaining the high ionic conductivity of liquid batteries while also possessing the high safety and structural stability of solid-state batteries.
