Graphene like graphite (GLG) samples containing various amounts of oxygen are prepared from the thermal reduction of graphite oxide (GO) and are used as anodes of lithium ion battery. The oxygen/carbon (O/C) ratios in GLG varied from 0 to 0.08, depending on the thermal reduction temperature, oxygen gas pressure during heat treatment and degree of oxidation of the starting GO. The cell voltage during discharge almost linearly increases below 1 V independent of the oxygen contents in them. The discharge capacity of GLG above 1 V increases with the increase in the oxygen content with a slope of lithium/oxygen ratio of 3 at lower O/C ratios. Then the slope becomes smaller and the discharge capacity reaches 673 mAhg⁻¹ for GLG with O/C = 0.08. When GLG is treated with hydrogen gas, considerable amounts of oxygen atoms are substituted by hydrogen ones. The discharge capacity of the resulting GLG samples is larger than that expected form their oxygen contents and coulombic efficiency is slightly improved up to 59%. Introduction of oxygen atoms within carbon layers results in the large increase in the interlayer spacing during charging, which leads to accommodation of large amounts of lithium ions.

通过氧化石墨（GO）的热还原制备包含各种氧气的石墨烯样石墨（GLG）样品，并将其用作锂离子电池的负极。GLG中的氧/碳（O / C）比在0到0.08之间变化，具体取决于热还原温度，热处理过程中的氧气压力和起始GO的氧化程度。放电期间的电池电压几乎线性地增加到1 V以下，而与其中的氧含量无关。在较低的O / C比下，高于1 V的GLG的放电容量随氧含量的增加而增加，锂/氧比的斜率为3。然后斜率变小，放电容量达到673 mAhg ^-1对于O / C = 0.08的GLG。当GLG用氢气处理时，大量的氧原子被氢原子取代。所得GLG样品的放电容量大于其氧含量所预期的放电容量，库仑效率略有提高，最高可达到59％。碳层中引入氧原子会导致充电过程中层间间距大大增加，从而导致容纳大量锂离子。
