Lithium-ion Battery Equal 500 kilometers

Shenzhen Sinoli Electronic Co.,Ltd | Updated: Dec 29, 2018

On December 27, Japanese media reported that the development of lithium-ion battery technology equivalent to 500 kilometers from Tokyo to Osaka for a single charge is becoming more and more active in Japan, and it is expected to be realized in middle of 2020.


Lithium-ion batteries were commercialized in 1991 and were used in laptops and cameras. It was used in mass-produced pure electric vehicles in 2009. Fully charged driving distance is about 200 kilometers. It is generally believed that the technology at that time could not reach 500 kilometers in the early 2010's and would be replaced by new generation batteries such as all-solid-state batteries around 2030.


The development of new generation batteries is becoming more and more active in the world, but there are many technical issues. On the other hand, the technological development of lithium-ion batteries has made progress, and the breakthrough of 500 kilometers is becoming more and more realistic. Researchers and others predict that lithium-ion batteries will continue to be used for about 10 years. Lithium-ion batteries generate electricity and charge by moving lithium ions between positive and negative electrodes. To increase the capacity of batteries, it is necessary to increase the ions stored in the electrodes, or to reduce the internal resistance, so that electrons can pass through more easily.


In addition, Japan's Ministry of Economy, Industry and Industry will develop technologies to make it possible to completely run out of lithium-ion batteries starting in 2019. In order to prevent fire accidents and so on, batteries are used with capacity below the upper limit. The development of sensors that can accurately detect residual electricity will be supported to increase usage. Include 250 million yen in the budget for 2019, and strive to achieve practicality by 2023.
