Portable electronic devices (PEDs) are promising information‐exchange platforms for real‐time responses. Their performance is becoming more and more sensitive to energy consumption. Rechargeable batteries are the primary energy source of PEDs and hold the key to guarantee their desired performance stability. With the remarkable progress in battery technologies, multifunctional PEDs have constantly been emerging to meet the requests of our daily life conveniently. The ongoing surge in demand for high‐performance PEDs inspires the relentless pursuit of even more powerful rechargeable battery systems in turn. In this review, we present how battery technologies contribute to the fast rise of PEDs in the last decades. First, a comprehensive overview of historical advances in PEDs is outlined. Next, four types of representative rechargeable batteries and their impacts on the practical development of PEDs are described comprehensively. The development trends toward a new generation of batteries and the future research focuses are also presented.

“…Besides, Chen et al. reported a flexible Li‐CO 2 battery with liquid‐free electrolyte, showing a long cycle life at moderate temperature (55 °C) very recently . However, the low ionic conductivity of liquid‐free electrolyte limits the cycling capability and rate performance at room temperature.…”

A Rechargeable Li‐CO₂ Battery with a Gel Polymer Electrolyte

The utilization of CO in Li-CO batteries is attracting extensive attention. However, the poor rechargeability and low applied current density have remained the Achilles' heel of this energy device. The gel polymer electrolyte (GPE), which is composed of a polymer matrix filled with tetraglyme-based liquid electrolyte, was used to fabricate a rechargeable Li-CO battery with a carbon nanotube-based gas electrode. The discharge product of Li CO formed in the GPE-based Li-CO battery exhibits a particle-shaped morphology with poor crystallinity, which is different from the contiguous polymer-like and crystalline discharge product in conventional Li-CO battery using a liquid electrolyte. Accordingly, the GPE-based battery shows much improved electrochemical performance. The achieved cycle life (60 cycles) and rate capability (maximum applied current density of 500 mA g ) are much higher than most of previous reports, which points a new way to develop high-performance Li-CO batteries.

“…However, Li–S batteries generally suffer from poor cycling stability . The stability of the Li anode is one of the most important factors that can influence the stability of Li–S batteries . On the one hand, lithium dendrites are easy to generate because of the inhomogeneous deposition of Li + ions during the charge and discharge processes .…”

Lithium-sulfur (Li-S) batteries have shown great potential as high energy-storage devices. However, the stability of the Li metal anode is still a major concern. This is due to the formation of lithium dendrites and severe side reactions with polysulfide intermediates. We herein develop an anode protection method by coating a Nafion/TiO composite layer on the Li anode to solve these problems. In this architecture, Nafion suppresses the growth of Li dendrites, protects the Li anode, and prevents side reactions between polysulfides and the Li anode. Moreover, doped TiO further improves the ionic conductivity and mechanical properties of the Nafion membrane. Li-S batteries with a Nafion/TiO -coated Li anode exhibit better cycling stability (776 mA h g after 100 cycles at 0.2 C, 1 C=1672 mA g ) and higher rate performance (787 mA h g at 2 C) than those with a pristine Li anode. This work provides an alternative way to construct stable Li anodes for high-performance Li-S batteries.
