Natural Solution to Large-Scale Energy Storage

Professor Xavier Crispin and research engineers Ujwala Ail and Ziyauddin Khan, at the crimper that manufactures coin cell batteries to prove the concept, in the Laboratory of Organic Electronics.

The old saying goes that you could wait for hours to catch a bus and then two come along at once. The subject of last week’s TechTalk was how cellulose derived from trees could be used to make the electrolyte for a solid-state battery that may overcome the previous downsides to the technology (their brittleness

Figure 1: By 2030, Battery Electric Vehicles (BEV) will account for 45% of all xEVs

For years, automakers have been continuously challenged with the need for more power. In the early days, cars were powered with a six-volt battery right up to the mid 1950s when automotive systems evolved to a 12V power source to meet the perpetual need for more power. Not only did automakers have to anticipate ne

Trees could be the key to better, safer batteries
One of the downsides of Lithium-ion batteries is that they can be unsafe if stressed, meaning they have to be treated with care and respected. If they are stressed by an internal short, excessive heat, or physical damage, for example, then they can catch fire or even explode. Using individual cells in large co

Wireless communication without batteries?

Muhammad Sarmad Mir, PhD Student at IMDEA Networks and one of the authors of the scientific paper “PassiveLiFi: Rethinking LiFi for Low-Power and Long Range RF Backscatter”

While batteries are more popular than ever, there are still some downsides to using them. Those problems will grow as our reliance on them increases. Lithium is in short supply, it can explode and it is difficult to recycle. Despite those problems, lithium-based batteries are the best solution that we currentl
