Although organic electrode materials have many advantages, their applications in batteries still face many technical challenges. 11 First of all, the low density of organic electrode materials (<2 g cm −3) leads to a low bulk energy density of the battery. Moreover, the low electronic and ionic conductivities of organic electrode materials

Battery Capacity. Battery capacity or Energy capacity is the ability of a battery to deliver a certain amount of power over a while. It is measured in kilowatt-hours (product of voltage and ampere-hours). It determines the energy available to the motor and other elements. The rate is dependent on the amount of current being transferred by the battery as the voltage is

Therefore, cathode materials with high-capacity and high-voltage as well as anode materials with high-capacity and low-voltage have been developed to improve the energy densities of LIBs. This review will mainly focus on the anode materials. C, P, Si, and Li delivers a theoretical specific capacity of 372, 2596, 3579, and 3861 mA h g
An obvious approach to increasing the energy density of an ion battery is to use insertion cathodes with higher potential or charge capacity. High voltage cathodes for LIBs have been a popular research topic over the past couple of decades as a result, most of which are based on polyanion oxides due to the inductive effect, such as LiCoPO 4
Lithium-ion (Li-ion) batteries are considered the prime candidate for both EVs and energy storage technologies , but the limitations in term of cost, performance and the constrained lithium supply have also attracted wide attention , .
The new development overcomes the persistent challenge of voltage decay and can lead to significantly higher energy storage capacity. Lithium-ion batteries (LiBs) are widely used in electronic devices, while lithium- (Li) and manganese-rich (LMR) layered oxides are a promising class of cathodes for LiBs due to their high capacity and low cost.
Aqueous rechargeable batteries based on organic-aluminum coupling show promise as alternatives to lithium-ion batteries but require further research for improved performance and scalability.

A pivotal breakthrough in battery technology that has profound implications for our energy future has been achieved by a joint-research team led by City University of Hong Kong (CityU). The new development overcomes the persistent challenge of voltage decay and can lead to significantly higher energy storage capacity.
Columbia Engineers have developed a new, more powerful “fuel” for batteries—an electrolyte that is not only longer-lasting but also cheaper to produce. Renewable energy sources like wind and solar are essential for the future of our planet, but they face a major hurdle: they don’t consistently generate power when demand is high.
Higher energy density batteries can store more energy in a smaller volume, which makes them lighter and more portable. For instance, lithium-ion batteries are appropriate for a wide range of applications such as electric vehicles, where size and weight are critical factors .
