A unnamed executive at Samsung, a South Korean battery maker, said on June 30 that the company would be able to produce solid-state batteries in the next 1-2 years, leaving smartphones completely out of the door, according to the Korean Herald. "Our technology to produce solid-state batteries for smartphones will reach a mature enough level over the next 1-2 years," said the Samsung SDI executive. As far as I know, our competitor (Lgchem) 's battery level is comparable to ours. ”

 

Solid-State batteries are a new generation of batteries that will replace lithium-ion batteries currently used in most smartphones and electric vehicles. Because such batteries use solid electrolytes rather than liquid electrolytes, the risk of fire or explosion is very low. When the internal liquid electrolyte flows out and touches the air or water, the battery usually explodes.

The development of solid-state batteries has recently received widespread attention as battery explosions have been a problem plaguing smartphones, including Samsung Galaxy and the iphone series. After a series of battery explosions last year, Samsung was forced to fully recall and stop selling Galaxynote 7.

 

"Solid-state batteries have been considered to be a realistic ' spare tire ' for lithium-ion batteries," said Choijung, an analyst at the LG Institute of Economics. ”

 

However, solid-state batteries will take longer to be used in cars, and it needs to pass stringent security checks because it is directly related to the safety of the driver's life.

 

The Samsung SDI executive said that "solid-state batteries will be used first in smartphones and will not be used in cars until security is fully tested." It may be used in cars for about 2025 years. ”

 

At present, Toyota has the world's most advanced solid-state battery technology. It has about 200 engineers developing solid-state batteries at the East Fuji Technology Center (Higashifuji Technical Center), with the goal of commercializing around 2020 years.

 

Unlike Toyota, Samsung SDI and LG Chem may announce the use of "solid-state" batteries for electric vehicles, rather than directly producing solid-state batteries. Compared with solid-state batteries, "solid-state" batteries – still partially liquid electrolytes – are safer and harder to produce than lithium-ion batteries.
