In 21, the global energy saving and emission reduction is very prominent, environment pollution and energy crisis has caused extensive attention all over the world. China government announced that by 2020 carbon emissions per unit of GDP than in 2005 dropped 40%-50%. The people more and more attention to the environment today, with the rapid development of green power.
Lithium ion battery with its high reversible capacity, high voltage, high energy density of karma, cycle stability, long cycle life, low self discharge, no memory effect, no environmental pollution and other beneficial properties favored, known as the twenty-first Century green energy and leading power, has the widespread civil and defense applications.
High purity spherical graphite as anode materials for lithium ion batteries, with high capacity, high cycle efficiency compared with the characteristics of the traditional artificial graphite. High purity spherical graphite charge discharge capacity is 360mAh/g, but the price is only half of the artificial graphite. As the anode materials for lithium ion batteries using high purity spherical graphite, not only reducing the cost, but also improve the performance of lithium ion battery.
