Cheap Thermally Modulated LFP Car Battery To Recharges In Just 10 Minutes

Scientists have invented a new type of electric car battery that is cheap and makes your car drive like a Porsche. The thermally modulated LFP battery, which can be recharged in just 10 minutes, makes a car that drives like a Porsche, according to the scientists.

The lithium-ion phosphate battery has a self-heating core that accelerates charging and recharging. In recent years, it has been shown that heating the battery during charging reduces the accumulation of dendrites on the anode and increases its ability to absorb charge quickly by accelerating the chemical process.

A team from Penn State University in the US claims to be able to travel 250 miles on a single charge in just 10 minutes. This means, according to the researchers, that they can quickly charge and discharge during use, and then cool down quickly when not in use. The new tech heats the battery up quickly to 60 degrees Celsius allowing fast charging.

It does not require expensive and rare materials used in conventional lithium-ion batteries, and the self-heating method also promises cost savings. 

The battery uses a self-heating approach previously developed at Wang’s center, using two nickel foil electrodes, one attached to the negative terminal and the other extending into the cell to create a third terminal. Scientists have added a third connector to each battery – a nickel heater – which heats up the cells before charging so that it can optimally accept a faster charge, then they thermally cool the battery down.

As soon as the internal temperature of a battery exceeds 140 degrees Celsius, a switch is opened at the end of each charging and discharging cycle. 

Tesla and Porsche recently installed 250 kilowatts of power that can charge an electric battery to full capacity in about 40 minutes.

Frank Vitetta from Batterino states: “If we want to electrify our roads, we need affordable electric batteries that can be recharged even faster. To increase the uptake of electric vehicles, we must offer this segment of society a way to pay for it quickly. Moreover, there is a huge demand for electric cars, not only in the US, but also worldwide.”

The science

Boosting a lithium-ion battery’s charge rate involves trade-offs. During charging, lithium ions flow from the cell’s cathode to its anode, which is typically made from graphite, a type of carbon. The anode is like a bucket that collects and stores the ions while the battery is charging. Thicker anodes—bigger buckets—can hold more energy in the form of lithium ions, which allows electric cars to go further on a single charge.

Thick anodes and larger buckets store more energy in the form of lithium-ion, so electric cars can continue on a single charge. Thick anodes can make it difficult to charge quickly, however, as the ions in an ode continue to travel along a winding path.

This phenomenon, known as lithium plating, can suppress the performance of the battery and cause lithium to reach the surface. If the ions cannot penetrate the anode fast enough to charge, this causes a molecular jam and can cause the ion to penetrate too far into the lithium surface where it accumulates in the electrolyte.

When enough ions are stacked on the surface of the anode, they can form so-called lithium dendrites, i.e. spindles that break the barrier between the anode and the battery electrolyte.

London electrically powered forecourt

The petrol and diesel ban means Britain needs new and efficient charging methods to complement more electric charging ports across the country. Britain’s first electrically powered forecourt has opened in London, giving motorists the chance to recharge their vehicles. The petrol station has 36 electric vehicle shops, including one where visitors can practice yoga while charging their electric vehicles, as well as a range of other services.

The electric vehicle forecourt is part of a $100 billion electric grid planned for the next five years. 

Meanwhile, Coventry City Council is working on a Scalextric-style wireless charging system to charge electric vehicles when they are on the road.

  1. It seems like the big feature here is putting heating mechanism inside the cell itself, which is pretty cool. Basically one of the layers in the jellyroll is a heating element with one end connected to the negative terminal, and the other end connected to a third terminal. Connect that third terminal to the positive, and the cell evenly heats up from the inside.

  2. the grid will never handle the draw current when 1000’s of these get rolled out, if it takes 1/10 the time to charge, then it takes 10x the current from the grid to charge
