Composition Analysis And Development Prospect Of Lithium Ion Battery

    The lithium-ion battery was first developed in 1990 by Sony Corp. of Japan. It is the lithium ion embedded in carbon (petroleum coke and graphite) to form a negative electrode (traditional lithium batteries lithium or lithium alloy as cathode). Cathode materials are commonly used in LixCoO2, also with LixNiO2, and LixMnO4, electrolyte with Lipf6 two vinyl carbonate (EC) + two methyl carbonate (DMC).Lithium Ion Battery
    Petroleum coke and graphite as cathode materials are non-toxic, and sufficient resources, lithium ions embedded in carbon, to overcome the high activity of lithium, to solve the traditional lithium battery security problems, the positive LixCoO2 in charge, discharge performance and longevity can reach a higher level, so that the cost is reduced, in short, the comprehensive performance of lithium-ion batteries improved. It is expected that lithium-ion batteries will occupy a large market in 21st century.Lithium Ion Battery
    Difference: Lithium-ion batteries are easy to confuse with the following two kinds of batteries: (1) Lithium battery: lithium metal as cathode. (2) Lithium-ion battery: The use of water-liquid organic electrolyte. (3) Lithium-ion polymer batteries: The use of polymers to gel liquid organic solvents, or directly with all solid-state electrolytes. Lithium-ion batteries are usually graphite-like carbon materials as cathode.Lithium Ion Battery
    Throughout the history of battery development, it can be seen that the current development of the world battery industry three characteristics, one is the rapid development of green environmental protection batteries, including lithium-ion batteries, Ni-MH batteries and so on; second, a battery to the battery to convert, which is in line with the sustainable development strategy; In the commercial rechargeable pool, the lithium-ion battery has the highest energy, especially the polymer lithium-ion battery, which can realize the thin shape of the rechargeable pool. Because the volume of lithium-ion batteries than energy and quality is higher than energy, can be charged and non-polluting, with the current battery industry development of the three characteristics, so in the developed countries have a faster growth. The development of telecommunications and information markets, especially the large use of mobile phones and laptops, has brought market opportunities to lithium-ion batteries. Lithium-ion batteries in the polymer lithium-ion battery with its unique advantages in safety, will gradually replace the liquid electrolyte lithium-ion battery, and become the mainstream of lithium-ion batteries. Polymer lithium-ion battery known as the "21st century Battery", will open up a new era of battery, the prospects for development is very optimistic.
