autonomous cars need tougher batteries, lithium-ion pioneer says - lithium ion rechargeable battery
If predictions of a wave of self-waves, battery manufacturers must rethink their technology
According to one of the inventors of lithium, driving a car is a success. ion battery.
In addition to focusing on making the battery more powerful to extend the drive range of a single battery
Car owners, manufacturers also need to develop near-affordable-
Continuous driving and short
Akira Yoshino said that starting with the co-use of driverless cars, he invented a prototype of lithium
Ion battery in 1985
"A car shared by 10 people means it will run more than 10 times," said Yoshino, an honorary researcher at Asahi Kasei Corp.
The world's largest battery separator manufacturer said in an interview with the company's headquarters in Tokyo.
"Durability will become very important.

While producers should still focus on increasing energy density and reducing costs, they also need to use materials that can better withstand constant expansion and contraction to make batteries, Yoshino said.
He said the task would become easier without the need to increase energy density at the same time, the biggest factor in driving range.
For example, titanium lithium can be used as an anode for batteries, and carbon is now commonly used.
"Cars are a brand new app and we have to wait until we find out what kind of battery is really needed," Yoshino said . ".
"The future of the battery depends on the future of the automotive society.
In the 1980 s, in the laboratory of Xucheng, Yoshino began to study the conductive polymer polyacetylene discovered by Japanese chemist and Nobel Prize winner Shirakawa Xiu tree.
While this material can be used in solar panels and semiconductors, Yoshino focuses on batteries as small electronic devices that require powerful rechargeable energy are starting to enter the market.
He succeeded in making a lithium.
An ion battery that uses polyacetylene as an anode and later switches to carbon. But Sony Corp.
In 1991, the mobile phone commercial competition beat Xucai.
In the second year, the company established a joint venture with Toshiba.
Make and sell batteries yourself.
"I think it would be a gospel to enter 8mm --
Yoshino said he was referring to an outdated format.
"Mobile phones, laptops and computers have been multiplying, but no one was thinking about cars at the time," he said . ".
This has changed.
Bloomberg New Energy Finance expects electric vehicles to account for 54% of new car sales by 2040.
Highly autonomous cars are expected to reach about 2020, but technically and legally, on a large scale
BNEF said in 2030 that the market use of fully self-driving cars would not be resolved by December. 1 report.
Yoshino is the winner of the 2014 Charles Stark Draper engineering award for their contribution to lithium developmention battery.
