The development trend of notebook batteries
Laptop batteries as an important part, since the birth of a mobile office caused widespread concern in the group. With notebook computers and handheld electronic products, rapid technological development, and stability of their people, time, size and even the number of charge, charge time, and so on have a higher demand, and the battery technology to market demand, in many Has made the improvement and development.
To reduce the volume, at the same time to extend the use of time, increasing the frequency of use, to reduce the memory effect by the negative impact of purpose, taking into account the cost of batteries and the use of the safety, battery material in the continuous refinement. To the lithium-ion battery cathode material, for example, the current can be broken down as a lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide and other raw materials. From a technical point of view, the current lithium cobalt oxide battery to the main. In order to further enhance the product’s energy reserves, higher levels of technology for lithium nickel materials is expected to enter the market in 2000. However, as cathode materials for batteries have a limited impact on the characteristics of their own, according to expert estimates that by 2000, the volume of lithium-ion battery energy density of about 400wh / l, while single battery should be the minimum thickness of 4 ~ 5mm, Performance in almost do not have much room for development.
Overall, the development of lithium-ion battery to replace the battery urgent new generation, professional and battery manufacturers are also actively carry out research and development and material selection. In the lithium cobalt oxide is expected to replace the new materials, rechargeable lithium batteries became the focus of attention. Rechargeable lithium battery anode materials belonging to the direct use of a new type of rechargeable lithium metal batteries, the largest of its features can give full play Anode metal battery materials, so that a new type of battery energy reserve to meet the traditional lithium-ion battery more than two times in the discharge Capacity, and even reach 10 times that of conventional products. Lenovo computer company has been dedicated high-performance notebook PC’s battery development, in putting in a lot of funds to carry out independent research, professional and battery manufacturers to maintain close ties to China to provide efficient and economical battery-to-date technology.
Zinc air battery is replaced by lithium cobalt oxide in the best new materials, and its use of zinc anode, the very characteristics. At present, the zinc air battery charge in the free area there is still a problem, but the majority of battery manufacturers are actively seeking solutions to believe that the mature cells of zinc products will be available soon. —- It is envisaged that in the near future, be it notebook computer manufacturers or users will face more and more efficient and more practical choice, and many new technologies and new materials of the birth of battery The battery market in the future will have a revolutionary impact.116314-001 , 134111-B21 , 135214-002 , 138184-001 , 146252-B25 , 159524-001 , 182281-001 , 190336-001
