“…Many researchers have effectively adjusted and controlled the tunnel volume in electrode materials for nonaqueous batteries, which is easy in those with 2D diffusion tunnels. [ 76 ] H 2 O molecules (coinserted and/or lattice H 2 O) can provide the ions with new topological pathways to achieve fast energy storage. Thus, in this section, the materials are classified by the tunnel dimension to discuss their unique electrochemical properties for fast ionic storage.…”

The highly dynamic nature of grid‐scale energy systems necessitates fast kinetics in energy storage and conversion systems. Rechargeable aqueous batteries are a promising energy‐storage solution for renewable‐energy grids as the ionic diffusivity in aqueous electrolytes can be up to 1–2 orders of magnitude higher than in organic systems, in addition to being highly safe and low cost. Recent research in this regard has focussed on developing suitable electrode materials for fast ionic storage in aqueous electrolytes. In this review, breakthroughs in the field of fast ionic storage in aqueous battery materials, and 1D/2D/3D and over‐3D‐tunnel materials are summarized, and tunnels in over‐3D materials are not oriented in any direction in particular. Various materials with different tunnel sizes are developed to be suitable for the different ionic radii of Li+, Na+, K+, H+, NH4+, and Zn2+, which show significant differences in the reaction kinetics of ionic storage. New topochemical paths for ion insertion/extraction, which provide superfast ionic storage, are also discussed.

“…In the previous work, it has been proved that the electronic conductivity can be enhanced by doping, coating, and 3D conductive network, [ 43–47 ] while the ions diffusion of the materials can also be enhanced by various nanostructures and decreased tortuosity ( Figure 3 a). [ 48–50 ] Readers could refer to a few references [ 51–53 ] for a good review of strategies to improve conduction in SIBs.…”

Sodium‐ion batteries, with their evident superiority in resource abundance and cost, are emerging as promising next‐generation energy storage systems for large‐scale applications, such as smart grids and low‐speed electric vehicles. Accidents related to fires and explosions for batteries are a reminder that safety is prerequisite for energy storage systems, especially when aiming for grid‐scale use. In a typical electrochemical secondary battery, the electrical power is stored and released via processes that generate thermal energy, leading to temperature increments in the battery system, which is the main cause for battery thermal abuse. The investigation of the energy generated during the chemical/electrochemical reactions is of paramount importance for battery safety, unfortunately, it has not received the attention it deserves. In this review, the fundamentals of the heat generation, accumulation, and transportation in a battery system are summarized and recent key research on materials design to improve sodium‐ion battery safety is highlighted. Several effective materials design concepts are also discussed. This review is designed to arouse the attention of researcher and scholars and inspire further improvements in battery safety.

“…The most widely used energy storage system is lithium ion battery, however, the lack of lithium has forced us to develop an energy storage device that can replace lithium ion batteries. And more scholars turn their attention to sodium ion battery, potassium ion battery, magnesium ion battery and aluminum ion battery (AIB) . AIB is a promising energy storage system to substitute for lithium ion battery owing to advantages such as low‐cost, abundant Al source, low flammability and high theoretical specific capacity .…”

Aluminum ion batteries have attached more attention because of inherent advantages such as abundant Al source, low flammability, three‐electron‐redox property and high theoretical capacity. However, many problems exist in the electrolyte system of aluminum ion battery, such as high price, low capacity. We prepare a novel AlCl3/Benzyltriethylammonium chloride electrolyte for aluminum ion battery. The battery displays a good performance at high current densities: 102 mA h g−1 at 5 A g−1 with a coulombic efficiency of ∼98% and 91 mA h g−1 at 10 A g−1 after 1500 cycles. It only takes 13 seconds to be fully charged/discharged at the current density of 25 A g−1. The mechanism of intercalation/de‐intercalation of chloroaluminate anions is confirmed by characterization and we believe AlCl3/Benzyltriethylammonium chloride will be a promising electrolyte for aluminum ion batteries.
