There are many kinds of positive electrode materials of the lithium-ion battery, which can be divided into lithium cobaltate, lithium manganate, three-yuan material, lithium iron phosphate, etc. according to the positive electrode material. Trimer lithium battery refers to a lithium battery using three transition metal oxides using nickel, cobalt, manganese, as a positive electrode material. Since it is combined with lithium cobaltate, lithium nickellate and lithium manganese acid three types of materials, better than the above performance Any single set of positive electrode materials. The experimental analysis indicated that the elements of three differentiated prices formed a superlattice structure, and there was a significant synergistic effect between the three components, so that the material was more stable, and the discharge platform was as high as 3.6V, so it was considered to be * application prospects One of the positive materials. The ternary battery has excellent energy density, good safety and stability, support high-magnification discharge, etc. Widely used, and show strong development potential in the field of smart robots, AGV logistics vehicles, drones and new energy vehicles. At present, the study of the three-dimensional materials is mainly concentrated on the preparation of precursors, the synthesis of materials and the relationship between electrochemical properties and structures. Most of the transition metal elements Ni, Co, and Mn are present in + 2, + 3, + 4 valence, and only Ni2 + / Ni4 + and CO3 + / CO4 +, Mn are substantially not in the electrochemical reaction during charge and discharge process, respectively. Participate in electrochemical reactions, just play a function of stabilizing the structure. Regarding the preparation method, the industrially used synthesis method is: high temperature solid phase method, common precipitation method, sol - gel method, hydrothermal synthesis method, combustion method, etc. Trimetal materials are a combined lithium battery positive electrode material that changes the molar ratio of three materials in a certain range, and adds corresponding additives (binder, conductive agent, collective body, etc.), which can be obtained On the one hand, there are highlighted performance characteristics, such as power-type three-dimensional lithium batteries, capacity triples lithium batteries, ultra-low temperature ternary lithium batteries, etc.

Trimer polymer lithium battery
The ternary polymer lithium battery refers to a lithium battery having a positive electrode material using a three-dimensional positive electrode material of nickel cobalt-manganese acid (Li (Nicomn O2), and a lithium battery using a gel polymer electrolyte. The electrolytic solution is used as the transmission medium of ion motion, which is generally composed of a solvent and a lithium salt, and the electrolyte of the lithium secondary battery mainly has a liquid electrolyte, an ionic liquid electrolyte, a solid polymer electrolyte and a gel polymer electrolyte. The gel polymer electrolyte consists of a polymer, an organic solvent, and a lithium salt, and is prepared by mixing an organic electrolyte and solid polymer matrix. Due to the presence of gel state, the advantages of solid electrolytes and liquid electrolytes are combined. Since the electrolyte is limited to the polymer chain, there is also a high ionic conductivity in a wider temperature range (up to 10 -3S / cm). Its * large advantage is that the mechanical strength of the separator is high, and the film provides a large surface area. The thinner of the thin film, the higher the energy density, because more active substances can be embedded in the battery. In addition, the electrochemical stability is also very good, high temperature resistance, and most of the high temperature batteries on the market use polymer electrolytes.

Three-duty power lithium battery
The so-called power battery means that the battery supports high-magnification large current discharge, high power density, and is more energy released within the unit time. The magnification discharge capability refers to the capacity of the battery capacity in the case where the charge and discharge rate is increased. The magnification of charge and discharge is expressed by XC, and 1C means that the nominal capacity of the battery can be used in 1 hours, while the magnification discharge in 2C can be used for 30 min.
The power / magnification performance of the battery is closely related to the design of the battery, affected by various factors, such as electrolyte, diaphragm, active material, and the magnitude of the active particles, and the like. In the middle of these factors, the thickness of the electrode is the main factor affecting the capacity of high current discharge. The magnification discharge capacity can be greatly improved by thinning the electrode, since the thin electrode has a small electron impedance and ion impedance, but the electrode is thinned to cause less active quality in the electrode, so the battery capacity will be reduced. Therefore, the main technical challenge of the three-dollar power lithium battery is to increase the large current discharge capacity without reducing capacity.
For the three-dimensional lithium battery, the current research * Many, technical * mature is a Japanese Panasonic company, and the experimental phase has been able to achieve 30C discharge, which has successfully realized the commercial mass-produced power type 18650 three-dimensional lithium battery discharge The magnification is up to 12C, and the capacity is also up to 3300mAh. Domestic also has a high discharge rate, but the stability of the battery needs to be improved, especially after using a period of time, its cycle life and magnification discharge capacity will be greatly reduced. There is a study report that the magnification performance of lithium batteries can be improved by granules and modification.
