Li-ion battery capacity doubled

03.02.2015

Each user of mobile devices has repeatedly asked himself the question - when will global manufacturers decide to influence the current situation with the autonomy of their products and abandon standard lithium-ion or lithium-polymer batteries, replacing them with something more innovative? Alas, time goes by, the news about the next heavy-duty and long-lasting battery with fantastic characteristics one by one gets into the Network, and "things are still there."

Meanwhile, autonomy in smartphones and tablets is based, if we put aside the energy efficiency of the used components, on a simple rule: the larger the battery, the greater its capacity, and therefore the duration of work in the absence of an outlet. Given the total miniaturization of the thickness of devices, the concept clearly does not fit into the current trend of the mobile market, where users prefer the most compact gadgets.

There is a chance that the work of specialists from SolidEnergy can bring significant changes in the designated direction. The company's engineers, who are from the Massachusetts Institute of Technology, have demonstrated a prototype of a new type of ultra-thin lithium-ion battery that can be used for portable devices. It should be noted right away that we are not talking about cardinal changes at all, but the modernization of a standard battery. However, the novelty, nevertheless, is capable of storing twice as much energy in comparison with existing analogues with similar overall dimensions.

A two-fold increase was made possible by the production technology, in which SolidEnergy batteries simultaneously use both a solid electrolyte and a liquid one. In addition, the liquid electrolyte here is non-flammable due to special additive components, which increases the safety of such a battery.

In ultra-thin SolidEnergy batteries, the solid electrolyte is a polymeric membrane layer covering a lithium foil electrode that interacts with a liquid ionic electrolyte. According to the authors of the project, the serial production of new lithium-ion batteries does not require a large-scale re-equipment of the production line. As for the rest of the parameters, the demonstrated prototype after 300 full charges loses approximately 20% of its original capacity. And although at the moment the SolidEnergy management sees its batteries primarily in modular smartphones created as part of the Project Ara project, the company's plans are not limited to this.

A commercial batch of unique batteries for mobile phones and other electronics may appear in 2016, and in two years the company intends to prove itself in the automotive industry - the creation of batteries for electric cars.

Experts note that the main disadvantage of energy sources with liquid ionic electrolytes is their high cost and not too optimistic durability indicators.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Energy windows 13.02.2008

New translucent solar panels, developed by the Japanese firm Sharp, have been inserted into the windows of the firm's recently opened plant for the production of flat screens on liquid crystals.

In addition to generating electricity, thin-film silicon batteries shade rooms from the visible and infrared rays of the sun, reducing the need for air conditioning inside the building. The efficiency of transparent batteries is 11%.
