Composition Analysis And Application Market Of Rechargeable Lithium Batteries
Jun 30, 2017

    Rechargeable battery, is the charge of a limited number of rechargeable batteries, with the use of chargers. The market generally sells 5th, 7th, but also has 1th. The benefits of rechargeable batteries are economic, environmental protection, power, suitable for high-power, long time use of electrical appliances (such as Walkman, electric toys, etc.). Rechargeable battery voltage than the same type of disposable battery low, AA battery (No. 5th charge) is 1.2 volts, 9V rechargeable battery is actually 8.4 volts. Now the general charge can be around 1000 times. As of February 2012, there were only five kinds: Ni-CD, Ni-MH, lithium-ion, lead-storage and iron-lithium.Rechargeable Lithium Batteries
    The cathode plate material of Ni-MH battery is nickel oxide powder, the negative plate material is a hydrogen absorption alloy, and the electrolytic solution is potassium hydroxide solution. , the open circuit voltage of the battery is 1.2V. Lithium-ion batteries with LiCoO2 composite metal oxides on the aluminum plate to form an anode, using lithium-carbon compounds in copper coins to form a cathode, a polyolefin membrane separator with submicron pores between the plates is an organic solvent. The open-circuit voltage is 3.6V. Lithium polymer is an improved type of lithium-ion battery, no battery fluid, polymer electrolyte, more stable than ion battery. Open-circuit voltage 3.6V.Rechargeable Lithium Batteries
    Memory effect: The new battery, the electrode material of small grains, can get the largest surface area of the electrode. Because of the use of the battery content produced crystallization, crystal formation, the grain increase, also known as (passivation), reduce the usable electrode area, and the growth of the grain will cause self-discharge increase, so that the battery capacity is reduced, the performance is damaged. This is the memory effect. The memory effect occurs because the battery is partially charged and the discharge is not completely caused. Self-discharge rate: After charging the battery, even if not in use, will also gradually lose their electricity, the general temperature higher, self-discharge more significant.Rechargeable Lithium Batteries
     A new type of high performance, Low-cost potassium dual-ion battery technology, without changing the existing lithium battery cathode materials, the development of a new high efficiency and low cost lithium battery technology with universal aluminum foil cathode/integrated fluid design can not only reduce the weight and volume of the batteries, but also improve the quality and volume energy density, and greatly reduce the cost of manufacturing, and it also has wide universality. Using the technology of the battery, greatly improve the battery capacity, to provide continuous power for mobile phones, the results in the one years, not only in the basic research has made a number of breakthroughs and layout; At the same time, quickly out of the laboratory, toward the direction of industrialization of rapid production exhibition. With the progress of Chinese science and technology, more and more Chinese technology leading the world, mobile phone production of all aspects of rapid development, China from the manufacturing power, developed into a technology power.Rechargeable Lithium Batteries
