Northvolt’s factory, which is under construction, is set to be complete next year. The company is aiming to  (Image Credit: Northvolt)   European battery makers are getting ready to take advantage of huge “green” stimulus packages unveiled since the coronavirus pandemic. However, many recognize that it will be difficult to match the Asian battery giants that are currently dominating the mainstream market.   Companies like Sweden’s Northvolt and France&# ...
To create the material, the thin film is deposited via a pulsed-laser deposition process in the chamber. The bright plume represents the laser hitting the target and depositing the material. (Image Credit: Lane Martin, Berkeley Lab)   Even though capacitors are capable of rapidly storing and discharging electricity, they often have low energy densities compared to fuel cells or batteries. Supercaps and Ultracaps are a step in the right direction. However, researchers at the U.S. Department ...
A widely used and very popular battery tester in the maintenance sector is HIOKI's handheld BT3554. In less than three seconds it precisely measures the battery resistance at 1000 Hz as well as the battery voltage and it lets you make pass / fail comparisons based on freely defineable threshold values. Depending on the version this tester comes with test leads that are either straight or L-shaped. Alternatively there is a clip type test lead called HIOKI 9460 - this probe has a temperature senso ...
A research team has developed a method to turn common red bricks into an energy storage solution. (Image credit: University of Washington)   The growth of solar panels and wind turbine energy solutions may be great for renewable energy, but it poses a new problem: what do you do with the excess electricity? Some solutions include battery banks, fast-spinning flywheels, and underground vaults of air. One team of researchers has an unconventional solution that may work. All you need is a lot ...
The researchers successfully demonstrated the new zinc-air battery in the scorpion and worm toy robots. (Image Credit: University of Michigan)   Current stand-alone batteries are inefficient, too large, add significant mass to any robot design, and need a strong structure for support. Now, researchers at the University of Michigan have developed a new type of zinc-air battery that can be integrated into the robot’s structure. It also reduces weight and takes up less space in addition ...
Epishine is about to launch this interesting light energy harvesting (LEH) kit and has provided some early samples for evaluation.   Unboxing Here is an unboxing showing what might be expected in the kit:   LEH Kit Features Basically the LEH module is a light harvesting power supply that can deliver up to 20 mA and be set to output any one of 16 voltages in 0.1 V increments between 1.8V and 3.3V. The challenge for any solar power system is to convert variable low voltage and h ...
Researchers could make the conversion from solar energy to hydrogen fuel more efficient by using the machinery of photosynthesis. (Image Credit: Clay Banks, Unsplash)   Scientists from the Israel Institute of Technology have achieved record efficiency for solar-to-fuel conversion. Now, the team wants to integrate a photosynthesis device into the process to produce more efficient results. The team presented their findings at the American Chemical Society (ACS) Fall 2020 Virtual Meeting & ...
I'm selected for the STM32H7B3I-DK -  DISCOVERY KIT road test. I'm working on a touch screen GUI for my electronic load. In this post I'm trying a mock interface - see how I can switch between screens Thank you fellow roadtester jomoenginer for sending me a very good starting project.   image source: the mockup running in simulator mode on my laptop   Goal: Build an app with two screens, display data and info  I'm putting some light goals here. I've already checked oth ...
I received a preview of a light harvesting kit from Epishine and element14. Check my intro here. In this post, I'm checking the behaviour when you provide backup coin cell.     The setup is identical to the previous tests: 1.8 V output and 590 Ohm load. But with a 3 V coin cell added to extend the uptime.   source: annotated draft product brief   What this achieves is that, when the supercap voltage drops to 3.6 V, the circuit will use the coin cell energy to recharge ...
After putting out my initial review on the kit, I somehow felt the review to be a little incomplete, since the star of the show was the organic photovoltaic (OPV) panel and I didn’t really do much to test the panel on its own. The design of the kit doesn’t make it easy to test the panel independently of the harvesting circuit, but that doesn’t mean that it can’t be done.   After some head-scratching, I decided that if I was willing to give it a try even if it meant ...
Image shows the first piece of the tokamak being lowered. The reactor is expected to weigh 23,000 tonnes once the 5-year assembly phase is complete. (Image Credit: ITER)   On July 28th, engineers in southern France began the five-year assembly phase of the International Thermonuclear Experimental Reactor (ITER). This is the world’s largest fusion project, which is expected to operate in late 2025, generating 500MW of thermal fusion energy. Development was supposed to start in 1985, b ...
I received a preview of a light harvesting kit from Epishine and element14. Check my intro here. In this post, an analysis of the electronic properties. Charging, discharging, powering a load.   image source: my board, with probe wires soldered to the test points   The Test Conditions  I've set the output to 1.8 V. That's one of the voltages specified in Epishine's draft spec. Light conditions: my lab during daytime, on a bright summer noon. No direct sunlight or artificial ...
A little opportunity popped up recently, in conjunction with element14, to test an energy harvesting module. As there seems to be a lot of development of low-powered sensors and radios which can run from coin-cells for extended periods, the whole idea of being able to eliminate batteries or extend the lifetime of these devices can be quite attractive. As I am a photovoltaics/solar energy engineer by qualification and an interested electronics hobbyist with some equipment, I decided to jump on th ...
