Batteries

Today, most electrical devices and electric vehicles use lithium-ion batteries for power supply. These batteries, however, suffer from certain drawbacks concerning energy density and performance. One type of these batteries, called lithium-sulphur batteries, is able to offer more energy density and lower cost than the traditional graphite/metal oxide lithium-ion battery. The only problem is that their performance is often impaired by a...

The lithium-ion battery is one of the most common battery types for all sorts of technical devices. It can be used to power cell phones, laptops, power tools or electric vehicles. It is small wonder, therefore, that businesses around the world invest billions to make this industry grow. For many years now, scientists have been searching for electrode materials and electrolytes that can help improve lithium-ion batteries so that they...

One of today’s most challenging tasks in energy production and storage is to find a means to store energy for use at peak times when power is most expensive. Batteries are often paired with renewables to store energy produced at wind and solar farms and to stabilize the difference between demand and supply. The biggest problem with conventional batteries, however, is that developing a commercially-viable battery from readily available...
