Research progress of analysis of quick charge lithium ion battery

Source: 2020 - 04 - 11 19:08 hits: time fast rechargeable lithium ion batteries from the current research progress of analysis of quick charge lithium ion battery research, mainly concentrated in the anode materials, anode materials and electrolyte materials: the anode with lithium compounds or LiCoO2, LiNiO2, LiMn2O4, carbon anode with lithium compound LixC6 between the layers. A typical battery system are as follows: C | lipf6 - ec +DEC | LiCoO2 ( +) Positive response: LiCoO2 = Li1 - xCoO2 + xLi + + xe - The negative reaction: 6 c + li + xe - x = LixC6 total cell reaction: LiCoO2 + 6 = Li1 - c XCoO2 + LixC6 as anode materials embedded lithium compound reservoir is lithium ion. In order to obtain higher single battery voltage, should choose to have a high potential of lithium compounds. At present, in the study of the anode material, the embedding method of lithium ion and lithium ion compound choice has become the important direction of the anode materials research, the performance of the lithium ion battery play an important decisive role. Generally speaking, the name of the lithium ion polymer battery is 6 to 7 digits, thickness/width/height respectively. For example, PL6567100 is thickness is 6. 5 mm, width is 67 mm, height is 100 mm lithium-ion polymer battery. PL said battery belongs to polymer category. Lithium-ion polymer battery manufacturing process generally USES laminated flexible packaging, so the size of the change is very flexible and convenient. 3. Quick rechargeable lithium ion battery application prospect of lithium polymer battery ( Also known as polymer lithium battery) : high energy density, small volume, thin, light weight, high safety and low cost. Many obvious advantages, is a new type of battery. In shape, polymer lithium battery has the characteristics of thin, can according to the needs of different products made into any shape and capacity of the battery. The battery, the minimum thickness can reach 0. 5mm。 Compared with lithium ion batteries, lithium polymer battery has the following characteristics: ( 1) Leakage, no battery, battery does not contain liquid electrolyte, using colloidal solids. ( 2) Can be made into thin battery: 3. 6 v400mah capacity, its thickness can be thin to 0. 5mm。 ( 3) The battery can be designed into various shapes. ( 4) The battery can be bending deformation: the maximum bending capacity of the polymer battery is about 90 & deg; 。
