Solid battery capacity doubled and applied

Modern life is almost inseparable from batteries, but today's battery technology does not meet our needs -- they often run out of power at the wrong time. Scientists have been looking for better batteries since Thomas Edison sought ways to power his friend Henry Ford's Model T.

Now a new battery breakthrough seems to be close, and it's almost as close as we expect -- a new technology that will meet the demands of mobile phones for days. And it can increase the mileage of electric car users to more than 500 miles (about 804 kilometers).

Josh Duettner, CEO of Colorado Solid State Power, said: "Solid battery technology will begin to sail." His company is dedicated to the development of solid-state batteries, and last week established a partnership with BMW. BMW has plans to offer some form of the battery pack for each of its products over the next decade.

Today's lithium-ion batteries have greatly improved compared with earlier lead-acid batteries, nickel-cadmium batteries, and nickel-metal hydride battery technologies. But as the latest long-range electric vehicles, such as Tesla's Model 3 and Chevrolet's Bolt, begin to enter the market, they need to be equipped with more than 300 kilograms of batteries.

The attendant problem is that the battery takes hours to recharge and lithium-ion batteries are not cheap. Car battery prices have dropped to less than $200 per kilowatt-hour from about $700 in 2010, according to data from the battery industry. But 60 kilowatt-hours of batteries still cost more than $10,000 to meet the demand for a 200-mile electric car.

Solid state battery technology is expected to make a huge leap in three key areas, according to experts, one of which is that batteries of the same size can at least triple their power supply, which experts say is an increase in energy density. Ultimately, the energy density of the battery can be more than twice that of the existing battery. That would cause carmakers to halve battery size within the same range, or double the range and improve performance, such as an SUV that provides users with nearly 500 kilometers of range and a sense of sports car acceleration.

Duettner Garrett said: "Solid state battery technology is also possible to achieve ultra-fast charging. Charging your electric car is as simple as adding fuel to a fuel car. In other words, it takes only 5 to 10 minutes to be fully charged. As for prices, a new study by Boston Consulting estimates that lithium-ion batteries will be reduced to $70 per kilowatt-hour within seven years. Solid state batteries will be 20 % cheaper than lithium-ion batteries, according to analyst Xavier Mosquet.

The name solid battery comes from the fact that it uses ceramic materials to replace liquid electrolytes in general batteries. This is another advantage because liquids in lithium-ion batteries are as flammable as gasoline, which is why they are banned from aircraft in thespecial sector. Defects in lithium-ion batteries have led to many accidents.

BMW is by no means the only company planning to use solid-state battery technology. Toyota has also hinted that it will introduce the technology into the new U.S. factory's electric vehicle production line in 2021. Toyota, which has become one of the world's largest suppliers of lithium-ion batteries in an alliance with Japan this month, is also expected to work on solid-state battery technology.

Another active company is Dyson, a British ceramic manufacturer. In October 2015, it acquired Sakti3 technology, which was derived from the University of Michigan, which specializes in solid-state battery technology research and development. Earlier this year, Dyson announced plans to start its electric car unit using new batteries. It also plans to use this technology to improve the competitiveness of its wireless appliances.

Solid state battery technology has long been explored by researchers, and even industry leaders such as Duettner Garrett admit that they are not ready. Battery manufacturers, which have demonstrated the technology in their laboratories, must now ensure that solid batteries can be produced in large quantities and that they can be used in specific charging environments where electric vehicles operate daily. That is why it will take about five years for the new technology to become widely available.

But if battery makers can overcome the existing barriers to solid-state battery technology, and if the technology meets expectations, then it can make wireless devices large and small more capable of meeting the needs of daily life.
