“…The influence of the copolymer architecture on the thermodynamic properties has been first studied without LiTFSI on the block copolymers as well as on the pure A blocks, i.e., PEO 35 and cEO 23 (see Table 1). Figure 1a represents the PEO melting temperature, T m , as a function of ϕ EO , while Figure 1b shows the PEO degree of crystallinity, X c , as a function of ϕ EO .…”

“…These linear triblocks are labeled SEO x S_Y where x corresponds to the PEO molecular weight in kilograms per mole and Y to the proportion of PEO in weight percent. For the purpose of comparison, PEO homopolymers with molecular weights (M n ) of 35 and 100 kg mol −1 have been also characterized and are labeled PEO 35 and PEO 100 , respectively. For the comb A block, the NMP route requires the copolymerization of the poly(ethylene glycol) methyl ether methacrylate macromonomer (M n = 1.1 kg mol −1 ), with a comonomer to ensure polymerization control.…”

Optimization of Block Copolymer Electrolytes for Lithium Metal Batteries

et al. 2015

International audienceSafety is one of the most important criteria for electrochemical energy storage devices used in large scale applications such as wind or solar farms. In this context, solid polymer electrolytes based on nanostructured block copolymer electrolytes (BCEs) are promising because their properties can be finely tuned by adjusting simultaneously their block chemistries and polymer architectures. However, there is a need to rationalize the different properties of BCE that are optimal for battery applications. We produced by controlled radical polymerization a large number of BCEs based on either (1) linear poly(ethylene oxide) (PEO) or (2) comb PEO as the ionic conductor block, and polystyrene as the structural block. We varied the molecular weight of the PEO-based block, the composition, and the architecture (diblock vs triblock). We performed a systematic analysis of their thermodynamic, ionic transport, and mechanical properties. To verify the potential of BCEs as electrolytes, we evaluated their electrochemical stabilities. Laboratory scale batteries comprising the best BCEs and LiFePO4 as a positive active material were cycled at different rates and temperatures. This process allows the selection of the best architectures and compositions that had been successfully tested in battery prototypes and cycled for more than 600 cycles at high rates without any dendritic growth

The full potential of wireless devices remains unattainable due to limitations in battery performance. It is the thesis of the guest editors and contributing authors of this issue of MRS Bulletin that there is much room for improvement, that we are still far from the practical limits of the technology, and that materials research has the capability to pave the way for a new generation of rechargeable batteries that will offer a dramatic improvement in power delivery over anything available today. The basics of battery operation, including the relevant electrochemistry, are reviewed, unsolved problems are enumerated, and prospective solutions are indicated.

“…Approaches to further reduce battery size were typically based on self-assembly, by integrating nano scale components into macro/microscopic systems. Techniques included layer-by-layer deposition [11], and the use of aerogels [12], of self-organizing polymer composites [13], or of porous alumina membranes [14]. Most of these systems are, however, limited with respect to size, biocompatibility, drain rate, processing conditions, and/or surface passivation [15].…”

Nonobatteries: Decreasing Size Power Sources for Growing Technologies

Increasing need for portable nanoelectronic devices triggers the development of dimensionally small batteries. Nanobatteries are being designed for specific applications, including computer chips, micro-electromechanical systems (such as micro-actuators, micro-instruments, or micro-robots), or nanostructured medical devices. As the size of power source should be commensurate with the device it powers, battery miniaturization is an important design challenge faced by the battery community. Further advantages of such minute batteries include the long shelf life and a quick ramp up to full power. Hence, design may enable the nanobattery to stay dormant for several years, and then getting reactivated, so that it can provide immediately a burst of high energy.
