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. [**]nd 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.
