From the 1980s onwards, electronic technology has advanced by leaps and bounds development, the progress of human civilization in the footsteps of a variety of electronic devices rely on the rapid growth, with the rapid development of the information age, this dependency is growing. The constraints of these new ibm 92p1102 battery high-performance electronic devices is a major obstacle to the development of power. In particular the civilian portable electronic devices are small, lightweight direction, which requires energy to provide you with a battery of advantages: small size, light weight, high-energy, long service life, maintenance, pollution-free And so on. At present, in order to position the portable mobile communications systems, notebook PCs represented by portable electronic equipment, applications and so on batteries made higher. Ever-changing information age and electronic systems must adapt to the power requirements of the development of science and technology.
Lithium, atomic number 3, located in the periodic table in the first main group of the first, in known Metal atoms in the lightest (6.94), the most negative electrode potential (-3.045V), were elements from Greek, Is the intent of the “stone.” 1817 Swiss scientists have Afu Wei-tsung, through analysis of lithium in the long quarry found. Because of its potential in the most negative, with the appropriate matching cathode material consisting of hp HSTNN-LB31 power with superior performance. This has led to the world wide attention from researchers, from the 1970s to date research, lithium – manganese dioxide batteries, lithium – sulfur dioxide batteries, lithium – thionyl chloride lithium battery into a cell in the three most widely used System, the product series, as many as dozens.
Lithium – manganese dioxide battery features:
1, relatively low price: manganese dioxide as cathode active material used electrolytic manganese dioxide, lithium battery cathode active material of a relatively low-cost, large scale application.
2, high-performance compaq Presario 2100 power: its energy than the dry battery is 5 to 10 times (about 230Wh/kg or 500Wh / L), load voltage of 2.8V, voltage discharge relatively stable. Can be -40 ~ 50 ℃ within the scope of work;
3, long-life battery storage: at room temperature under the conditions of the storage battery life for more than 10 years, the drop in capacity of about 1%;
4, safe and reliable battery: The battery in the storage and discharge-free gas in the process of precipitation, good security;
5, a wide variety batteries: batteries, including button, column, rectangular three categories, each category there are different size and structure of the battery capacity from dozens to hundreds of milliamperes when an ranging. Therefore, to meet a variety of applications.
The development of lithium – manganese dioxide battery research significance
Since the lithium – manganese dioxide battery system for the use of non-organic electrolyte water, at low temperature viscosity increases, the conductivity dropped, resulting in Li-Mn02 batteries at low temperature only a small power output, even in battery design Structural changes are still unable to raise the nature of the battery system from the low-temperature performance. This has seriously hampered the system in the field of civilian applications. However, due to lithium – and lithium sulfur dioxide battery – Asia-sulfur battery, with the storage time, the output current and an increase in the use of toshiba PA3383U-1BRS ambient temperature of the lower electrode surface in the form of compact passive film, leading to the use of batteries will be significant Hysteresis voltage, according to different circumstances, the time lag can be as long as ten minutes, and there are two types of batteries have safety problems: Lithium – thionyl chloride battery system, when the 40y6799 battery aused by improper use of battery temperature, the product of the cathode discharge of sulfur And took place Lithium exothermic reaction, or lithium-carbon embedded with the possibility of thionyl chloride, or sulfur occurred in the intense heat response system allows the battery’s poor security; lithium – sulfur dioxide battery system itself, there is pressure, when the battery Improperly can cause an explosion or leak of sulfur dioxide gas, there is less security. The United States have begun using lithium – and lithium sulfur dioxide battery – thionyl chloride batteries appear endanger the safety of the reported incidents, with the twenty-first century has been increasing emphasis on environmental protection and reliable security system, the safety of lithium-good — Dioxide battery system further in-depth study will be the first lithium battery research priorities.
Domestic and foreign research and development trend
Europe and the United States from the mid-1990s, the transfer of energy research center of gravity, when lithium – manganese dioxide battery began to be taken seriously. Is the first multi-small cell type column, and then in the market interested in high-capacity battery technology has made remarkable progress. In front of the United States the use of a large number of Canadian development of the Blue Star Technologies, Inc., Ultralife Batteries Ltd, NY and Hternacell the company’s production of lithium – manganese dioxide battery, and can be higher than the capacity and power than the battery. Uitralife Co., Ltd. of the United States through the lithium battery – manganese dioxide battery of in-depth study, now in the same volume conditions, the lithium – than the lithium manganese dioxide battery – sulfur dioxide batteries to provide more than 50% of the energy, breaking the researchers over the years that the Lithium – as lithium manganese dioxide battery – sulfur dioxide battery than the high-energy point of view.
China’s momentum from the beginning of the end of the lithium-ah – manganese dioxide battery of independent development research, the development of a series of cylindrical lithium – manganese dioxide batteries and lithium-button campaign – manganese dioxide battery, in a number of large-scale research institutes focus on the general High characteristics of lithium – manganese dioxide battery, in the book-type lithium – manganese dioxide battery in underwater applications, special applications in the field of exploration of technology-based foundation. Typical of technology Success: book-type lithium – manganese dioxide battery 1mm can do the following; lithium – manganese dioxide battery power than to meet and exceed 580W/kg; lithium – manganese dioxide battery-to-weight ratio and energy to achieve more than 300Wh / kg.
Lithium – manganese dioxide battery is a lithium battery in the 21st century the most promising high-reliability, power and chemical pollution, with the nano-material technology, as well as low viscosity, good security system of multi-organic electrolyte Further research, lithium – manganese dioxide battery performance of the chemical will also be a greater degree of improvement with the establishment of specific energy, high-power, light and micro-electro-chemical characteristics of the new system, and enhance our high-tech electronics hp Pavilion ZE2000Market competitiveness. .
