[交流] Ceder被Goodenough鄙视了。。。 已有13人参与

最新的power sources上,Ceder最近发在Nature上ultra fast charge/dishcarge的文章被Goodenough等严重鄙视了。。。

To suggest that it is possible to charge lithium batteries
for an electric vehicle in seconds or even minutes is a misleading conclusion that is not
justified in the paper by Kang and Ceder (1); and although appealing, is particularly
deceptive for those less experienced in Li-ion battery technology。

Unfortunately, this is typically what you need to heat a four-story building! The problem is
further exacerbated by the heat being concentrated in the small volume of the battery, so
that this heat must be removed if you do not want your battery to be volatilized before the
end of the first charge. To water-cool the battery, for instance, dissipation of 60x106 J
would cause 170 liters of water to rise from room temperature to boiling point. So, an
electric current of 900 A on recharging is not recommended for safety even if charge
storage at his rate were possible.

太搞笑了。。。
