为什么电解铝是出了名的耗电大户？
Why is aluminum electrolysis notoriously power-hungry?
铝非常活泼，只能用电解法从熔融盐中制取。每生产1吨铝约耗电13000–15000度，加上巨大的槽电流，使铝工业成为用电大户。
Aluminum is so reactive it must be won by electrolysis of molten salt. About 13,000–15,000 kWh per tonne plus huge cell currents make it extremely electricity-intensive.

锂离子电池石墨负极充电时为何必须控制截止电压下限以避免锂金属析出?
Why must the lower cutoff potential of a graphitic anode be controlled during charging of a lithium-ion cell to avoid lithium metal plating?
石墨嵌锂后电位随嵌锂量下降,在高倍率或低温大电流充电时,负极表面极化会使局部电位降至0 V(vs Li/Li+)以下,锂离子来不及扩散进入石墨层间而在表面还原为金属锂。析出的锂一部分失去电活性成为死锂并消耗电解液,还会促进枝晶生长刺穿隔膜造成内短路。因此BMS需根据温度与倍率动态限制充电电流,把负极电位维持在析锂阈值之上。
As lithium intercalates, the graphite potential falls, and under high-rate or low-temperature charging the surface overpotential can push the local anode potential below 0 V vs Li/Li+, so Li+ reduces to metallic lithium on the surface instead of intercalating. Deposited lithium partially becomes electrochemically inert dead lithium while consuming electrolyte, and it promotes dendrite growth that can pierce the separator and cause internal short circuits. Battery management systems therefore limit charge current dynamically according to temperature and rate to keep the anode potential above the plating threshold.

锂离子电池石墨负极首次循环的库仑效率通常仅约80%至90%,这与SEI膜的形成密切相关:请说明SEI膜的成因与组成特征,以及碳酸亚乙烯酯作为成膜添加剂的作用机理。
Graphite anodes in lithium-ion batteries typically reach only about 80-90% first-cycle coulombic efficiency owing to SEI formation. Explain why and how the SEI forms, and how vinylene carbonate functions as a film-forming additive.
石墨负极嵌锂电位约0.1 V(相对于Li/Li+),低于常规碳酸酯溶剂的还原分解电位,首次充电时溶剂与锂盐在石墨表面被还原,生成的碳酸锂、烷基碳酸锂与聚合物沉积成一层离子导电而电子绝缘的钝化层,即SEI膜。VC分子中的碳碳双键降低了LUMO能级,使其更易还原,能在溶剂共嵌入石墨之前于更高电位优先分解,形成致密且富有机锂组分的薄界面膜。该膜阻止溶剂分子嵌入导致石墨层剥离,并减少活性锂的不可逆消耗,从而提升首次效率和循环寿命。
Lithium intercalates into graphite at about 0.1 V versus Li/Li+, below the reduction potentials of common carbonate solvents, so during the first charge the solvent and lithium salt are reduced on graphite; Li2CO3, lithium alkyl carbonates and polymers deposit into a passivation layer that conducts ions but blocks electrons - the SEI. The carbon-carbon double bond in VC lowers its LUMO, letting it reduce preferentially at higher potential before solvent co-intercalation starts and form a dense, organic-lithium-rich thin film. This film prevents graphite exfoliation driven by co-intercalated solvent and curbs irreversible lithium consumption, improving first-cycle efficiency and cycling stability.
