Who invented the battery

Besides powering cellular phones, laptops, digital cameras, tools and medical devices, Li-ion is also a candidate for vehicles. Li-ion has a number of benefits including a higher energy density, is easier to charge and does not have maintenance issues unlike nickel-based batteries. Nor does Li-ion suffer from sulfation that is common with lead-based systems. Electricity through magnetism, an alternative method of generating electricity besides static charge and battery, came relatively late.

In , Michael Faraday demonstrated how a copper disc provided a constant flow of electricity while revolving in a strong magnetic field. Faraday, assisting Davy and his research team, succeeded in generating an endless electrical force as long as the movement between a coil and magnet continued.

This led to the invention of the electric generator and then the electric motor. Shortly thereafter, transformers were developed that could convert alternating current ac to any desired voltage.

In , Faraday established the foundation of electrochemistry by publishing his laws of electrolysis. Once the relationship with magnetism was discovered in the mid s, large generators began producing a steady flow of electricity.

Motors followed that enabled mechanical movement and the Edison light bulb appeared to conquer darkness. The three-phase ac technology developed by Nikola Tesla enabled transmission lines to carry electric power over great distances.

Electricity was thus made available to humanity to improve overall quality of life. The invention of the electronic vacuum tube in the early s was the significant next step toward high technology, enabling the development of frequency oscillators, signal amplifications and digital switching. The discovery of the transistor in paved the way to the integrated circuit 10 years later.

The microprocessor ushered in the Information Age and revolutionized the way we live today. Humanity depends on electricity, and with increased mobility, people are moving more and more toward portable power storage — first for wheeled applications, then portability and finally wearable use.

Modern Battery Experiments The earliest method of generating electricity was by inducing a static charge in some substance. Early Batteries Volta discovered in that certain fluids would generate a continuous flow of electrical power when combined with a pair of dissimilar metals. Rechargeable Battery In John F. Electricity through Magnetism Electricity through magnetism, an alternative method of generating electricity besides static charge and battery, came relatively late.

They can range from sizes smaller than a pencil eraser to as large as 2, square meters 21, square feet. The largest battery in the world has the capacity to power the entire town of Fairbanks, Alaska, a city of about 12, people, for up to seven minutes in an emergency situation [source: Conway ]. Some of the first primitive types of batteries can be traced all the way back to the Parthians around B. The Parthians made a clay jar, filled it with vinegar, then put a copper cylinder inside of it with an iron rod sticking out of the top.

This early type of battery was used to electroplate silver. But it wasn't until the late s that scientists began conduct more serious experiments on electricity and its storage. Experiments were conducted that stored electricity or produced it, but none were able to create a continuous and controllable current of electricity.

That is, not until the Italian physicist Alessandro Volta came along. In , Volta created the first modern day battery when he built what came to be known as his voltaic pile. The pile was made of up of zinc and copper plates with vinegar- or brine-dampened pieces of leather or pasteboard placed in between each plate.

The plates were then stacked in alternating order one on top of the other with the bottom plate and the top plate acting as the positive and negative terminals. The nickel-iron battolyser, on the other hand remains stable when fully charged , at which point it can transition to making hydrogen instead. Besides creating hydrogen, nickel-iron batteries have other useful traits, first and foremost that they are unusually low-maintenance. They are extremely durable , as Edison proved in his early electric car, and some have been known to last upwards of 40 years.

The metals needed to make the battery — nickel and iron — are also more common than, say, cobalt which is used to make conventional batteries. This means the battolyser could have another possible role for renewable energy: helping it become more profitable. Like any other industry, renewable energy prices fluctuate based on supply and demand. On a bright, sunny day there might be an abundance of power from solar, which can lead to a glut and a dip in the price the energy can be sold for.

The battolyser, however, could help smooth out those peaks and troughs. The battolyser is one way to help balance the supply and demand of renewable energy from sources like solar and wind Credit: Alamy. The battolyser is not alone in this regard. More traditional alkaline electrolysers coupled with batteries can perform this function too, and are widespread in the hydrogen-producing industry.

Mulder thinks the battolyser can do the same thing for less money and for longer, thanks to the durability of the system. It is something that is making the battolyser's backers hopeful. And while hydrogen is the direct product of the battolyser, other useful substances can be generated from it too, such as ammonia or methanol, which are typically easier to store and transport. Once it's undergone rigorous testing there, the aim is to scale-up further and distribute the battolyser to green energy producers, such as solar and wind farms.

Ultimately, the battolyser's proponents hope it will reach gigawatt-scale — equivalent to the power generated by around utility-scale wind turbines. Though as well as scaling-up, Barton sees a role for smaller battolysers, which could help supply energy to mini-grids used by remote communities that don't live on main power grids.

Edison's laboratory in New Jersey was the birthplace of many of his inventions, both those that gained popularity in his lifetime and those that didn't Credit: Alamy. The fact that the battolyser's electrodes are made from relatively cheap and common metals may help. And unlike lithium, nickel and iron do not create large quantities of water waste when mined, nor are they linked to significant environmental degradation. Still, both Mulder and Barton see hurdles to overcome in terms of efficiency and capacity.
