Comparison of Lithium-ion Battery Cathode Materials and the Internal Stress Development

The need for development and deployment of reliable and efficient energy storage devices, such as lithium-ion rechargeable batteries, is becoming increasingly important due to the scarcity of petroleum. Lithium-ion batteries operate via an electrochemical process in which lithium ions are shuttled between cathode and anode while electrons flowing through an external wire to form an electrical c...

Report: Photoelectrochemically Rechargeable Zn-Air Batteries

This work aims to design photoelectrochemically rechargeable Zn-air batteries with improved energy and power density, energy efficiency and cycle life. Our plan is to solve the bottle-neck problem associated with air electrocatalysts by developing novel nanocarbon-inorganic hybrid materials for oxygen reduction and/or evolution with high efficiency and durability. Also, we are pursuing active a...

Tuning of voltage and cycle performance of organic-tailored rechargeable battery by organic chemical technique

Organic chemistry plays an important role in the development of high-performance rechargeable batteries exceeding Li-ion batteries using LiCoO2 as a cathode-active material. The authors implemented the high-capacity rechargeable batteries using trioxotriangulene (TOT) stable neutral radicals with four-stage redox ability as cathode-active materials. These batteries showed the capacity of 311 A ...

The birth of the lithium-ion battery.

Throughout the 1980s, the development of portable electronic products such as video cameras, notebook computers, and cell phones led to a growing need for rechargeable batteries with greater capacity, or reduced size and weight for a given capacity. However, conventional rechargeable batteries such as lead–acid batteries and nickel–cadmium batteries, as well as nickel–metalhydride batteries, wh...
