ABSTRACT
The improvement in battery science and technology is a critical link in the transition from fossil fuels to alternative energy sources. In particular, the emerging eld of nanotechnology promises not only higher-energy-density batteries but also rechargeable batteries with a longer lifetime. This chapter is an effort to elaborate on technological developments that are currently being undertaken for improving cathodes, anodes and electrolytes for rechargeable batteries by keeping the common characteristic of all these components as their nanoscale structure. After a brief summary of advances in lead-acid and nickel-based batteries, this chapter concludes with a brief summary on advances in lithium batteries, which are a major attraction for R&D at present.
