Battery Science – News and Features

It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers at ETH Zurich have now succeeded in uniting all of these characteristics in zinc metal batteries.

Organic batteries with redox-organic electrode materials (OEMs) can be synthesized from natural “green” materials. Scientists have now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.

A newly constructed primary battery system can effectively remove cadmium from the environment and generate electricity at the same time.

Observing the transport of lithium ions in a solid-state lithium-sulfur battery has revealed that sluggish lithium ions cause slow charging and discharging, limiting the performance of the battery.

Scientists have shown that fine-tuning interlayer interactions in a class of 2D polymers known as covalent organic frameworks can determine the materials’ loss or retention of desirable mechanical properties in multilayer or bulk form.

Researchers have discovered that metal-free, water-based battery electrodes could address the projected shortages of strategic metals and safety issues found in lithium-ion batteries.

Researchers have pioneered a technique to observe the 3D internal structure of rechargeable batteries for the first time.

A new, safer battery, tested for a thousand cycles in a test cell, can store far more energy than today’s common lithium-ion batteries.

A new battery design could help ease integration of renewable energy into the nation’s electrical grid at lower cost, using Earth-abundant metals.

A novel lithium-air battery design has been described that uses novel chemistry to increase the storage capacity of the battery by up to four times, compared to current lithium-ion technology.
