本文综述了锂离子电池技术的最新进展。我们首先描述了电解质领域的发展，特别注意离子液体，讨论了这些室温熔盐的预期应用，并列出了仍然阻止其实际实施的问题。然后，注意力集中在目前被认为是最有前途的提高电池的能量密度的电极材料。在阳极方面，讨论了高容量锡和硅锂合金的发展状况。我们表明，最有可能确保这些合金电极的商业开发的形态是涉及碳基纳米复合材料。我们最后谈到了超高容量电池，讨论了锂硫电池和锂空气电池的关键案例，并试图预测它们最终达到实际吸引人的储能系统地位的机会。最后，我们简要回顾了锂的储量，因为在全球从汽油动力汽车向混合动力和电动汽车转变的情况下，锂的大量使用。
A critical overview of the latest developments in the lithium ion batteries technology is reported. We first describe the evolution in the electrolyte area with particular attention to ionic liquids, discussing the expected application of these room temperature molten salts and listing the issues that still prevent their practical implementation. The attention is then focused on the electrode materials presently considered the most promising for enhancing the energy density of the batteries. At the anode side a discussion is provided on the status of development of high capacity tin and silicon lithium alloys. We show that the morphology that is the most likely to ensure commercial exploitation of these alloy electrodes is that involving carbon-based nanocomposites. We finally touch on super-high-capacity batteries, discussing the key cases of lithium-sulfur and lithium-air and attempting to forecast their chances to eventually reach the status of practically appealing energy storage systems. We conclude with a brief reflection on the amount of lithium reserves in view of its large use in the case of global conversion from gasoline-powered cars to hybrid and electric cars.
