The biodegradable battery

The number of data-transmitting microdevices, for instance in packaging and transport logistics, will increase sharply in the coming years. All these devices need energy, but the amount of batteries would have a major impact on the environment. Empa researchers have developed a biodegradable mini-capacitor that can solve the problem. It consists of carbon, cellulose, glycerin and table salt. And it works reliably.

Battery parts can be recycled without crushing or melting

Researchers at Aalto University have discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.

Creating Higher Energy Density Lithium-Ion Batteries for Renewable Energy Applications

Lithium-ion batteries that function as high-performance power sources for renewable applications, such as electric vehicles and consumer electronics, require electrodes that deliver high energy density without compromising cell lifetimes. In the Journal of Vacuum Science and Technology A, researchers investigate the origins of degradation in high energy density LIB cathode materials and develop strategies for mitigating those degradation mechanisms and improving LIB performance.

Improving High-Energy Lithium-Ion Batteries with Carbon Filler

Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible energy storage. Research reported in Applied Physics Reviews aims to offer a solution by showing how the inclusion of conductive fillers improves battery performance.

Spontaneous Formation of Nanoscale Hollow Structures Could Boost Battery Storage

An unexpected property of nanometer-scale antimony crystals — the spontaneous formation of hollow structures — could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.

Simple Self-Charging Battery Offers Power Solutions for Devices

A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries. In Applied Physics Reviews, researchers at the University of Porto and the University of Texas at Austin report making their very simple battery with two different metals, as electrodes and a lithium or sodium glass electrolyte between them.
