Embodiment 1
[0033] A kind of method utilizing peanut shell to prepare sodium ion battery electrode carbon material, comprises the following steps:
[0034] Step 1. After washing the peanut shells with ethanol and deionized water respectively, place them in a blast drying oven for 24 hours at 60°C;
[0035] Step 2. Place the dried peanut shells in a porcelain boat, use a high-temperature tube furnace to heat up to 800°C at a rate of 30°C / min under the protection of an inert atmosphere, and then heat-preserve and carbonize for 4 hours;
[0036] Step 3, after grinding the carbonized peanut shells into powder, sieve them through a 100-mesh sieve to obtain a peanut shell-derived carbon powder with uniform particles, which is the electrode carbon material for sodium ion batteries; image 3 It is the peanut shell derived carbon XRD pattern prepared in Example 1. Where the abscissa is the angle and the ordinate is the relative intensity. Depend on image 3It can be seen that there are obvious ...
