3-D Electrodes in Solid-State Batteries

Addionics is an Israeli startup in the rechargeable business. It is recently engaging in redesigning the battery architecture with respect to its electrode technology. The company wants to replace the regular 2-D electrode layer structure in traditional batteries. They want to integrate a 3-D electrode structure. They claim this will provide greater power and energy density, while also extending the life of the battery. Addionics has five commercial projects lined up. They are presently targeting Read more [...]

Smart Batteries with Sensors

Quick-charging batteries are in vogue now. Consumers are demanding more compact, quick-charging, lightweight, and high-energy-density batteries for all types of electronic devices including high-efficiency vehicles. Whatever be the working conditions, even during a catastrophe, batteries must be safe. Of late, the Lithium-ion battery technology has gained traction among designers and engineers as it satisfies several demands of consumers, while at the same time being cost-efficient. However, with Read more [...]

New Battery Technology for UPS

Most people know of the Lithium-ion battery technology in use mainly due to their overwhelming presence in mobile sets. Those who use uninterruptible power supplies for backing up their systems are familiar with the lead-acid cells and the newer lithium-ion cells. Another alternative technology is also coming up mainly for mission-critical facilities such as for data centers. This is the Nickel-Zinc technology, and it has better trade-offs to offer. But the Nickel-Zinc battery technology is not Read more [...]

Battery Electrolyte from Wood

Although there exist several types of batteries, all of them function with a common concept—batteries are devices that store electrical energy as chemical energy and convert this chemical energy into electricity when necessary. Although it is not possible to capture and store electricity, it is possible to store electrical energy in the form of chemicals within a battery. All batteries have three main components—two electrodes or terminals made of different metals, known as anode and cathode, Read more [...]

A Bending and Stretching Battery

All electrical and electronic equipment we use in our daily lives requires power to operate. Movable equipment depends on batteries for their mobility. We are used to various types of batteries, like dry cells, lead-acid batteries, rechargeable Ni-Cd and Li-Ion batteries, and so on. However, all the batteries in common use are rigid, non-flexing structures. That may be changing now, as some researchers have claimed to have created a battery that is flexible and stretchable like a snake but unlike Read more [...]

Wireless Charging and Electric Vehicles

In our daily lives, we are increasingly using wireless products. At the same time, researchers are also working on newer trends in charging electric vehicles wirelessly. With more countries now implementing regulations for fuel economy and pushing initiatives for replacing fossil-fuel based vehicles with those driven by electricity, automotive manufacturers have focused their targets on development of electric vehicles. On one hand there are technological advancements on lithium-ion batteries and Read more [...]

What is an Instantly Rechargeable Battery?

The batteries required to power them have so far impeded advancement of electric cars. A primary difference between vehicles powered by fossil fuels and those powered by batteries is that batteries tend to discharge with use and require a finite time to recharge, immobilizing the vehicle for that period. On the other hand, simply filling up the gas-tank with fossil fuel is enough to keep the car rolling on the road. However, that may be changing now.
Research at the Purdue University has led to Read more [...]

Battery Monitoring with Comparators

So many portable consumer electronics gadgets in use today use small, button- or coin-cell batteries. Sometimes it is necessary to monitor their state-of-charge (SOC) and health efficiently without affecting their SOC significantly, but this can be a challenge. However, simple low-power monitoring circuits for small batteries using comparators can overcome this challenge.
Managing Batteries in Portable Systems
Usually, the system engineer budgets the system power requirements carefully during the Read more [...]

Boosting Battery Life in IoT Devices

Earlier, the assumption was unused energy from the environment, machines, people, and so on could be used to power valuable devices and this would be done for free. The assumption was based on the convergence of four key technologies to enable mass adoption of energy harvesting—efficient voltage converters, efficient harvesting devices, low-power sensors, and low-power microcontrollers. However, it was soon realized that although energy harvesting does operate for free, the system needs investment, Read more [...]

Salt Water Makes Li-Ion Batteries Safer

So far, high-energy lithium-ion batteries were always a matter of concern on account of safety. If you wanted to remain safe from exploding batteries, an aqueous battery such as made from nickel/metal hydride would be preferable, but then it would give you lower energy.
Usually, 3-V batteries using aqueous electrolyte technologies are unable to achieve higher voltages because of the cathodic challenge. This happens as the aqueous solution degrades one end of the battery made from either lithium Read more [...]
