东京大学:发明更好的电池

Meet Yuki Yamada — Building better batteries

I’m Yuki Yamada,
我是山田佑希
a lecturer at the Yamada-O kubo Laboratory
就职于东京大学山田大久保实验室
in The University of Tokyo.
担任讲师
I study electro-chemistry
我的研究方向是电化学
and it’s principle application is lithiumion batteries
其主要应用于锂离子电池
or rechargeable batteries.
也就是充电电池
You use lithiumion batteries every day
你每天都要在手机 电脑
in smartphones, in laptops and even cars.
甚至是汽车上用到锂离子电池
But there are many problems with lithiumion batteries.
但锂离子电池还有很多问题
For example the energy density, the longevity
比如说能量密度 使用寿命
and also the safety.
还有安全问题
The purpose of my research is to make a new battery
我的研究目的是研发出一种
system that can safely store a large amount of energy.
新型的 安全的 大容量电池系统
Rechargeable batteries are composed of
充电电池由
electrodes and electrolyte.
电极和电解质组成
The electrodes store charge,
电极储存电荷
and the electrolyte transports the charge.
电解质运送电荷
And they together power the electronic device.
它们一起为电子设备供电
When I was a high school student
我在高中的时候
I liked chemistry the best.
最喜欢化学这门课
So I decided to major in chemistry at university.
所以我决定要在大学主修化学
Also I was interested in the energy problem.
我对能源问题也很感兴趣
So I wanted to be a researcher
所以我想成为一名科研人员
to challenge this problem.
来挑战这个问题
The most exciting moment of my career was
我职业生涯中最激动的时刻
I worked with my student to discover a new aqueous electrolyte.
就是和学生一起 发现新的含水电解质
This water-based electrolyte is safe
这种水性电解质不易燃
because it is not flammable,
非常安全
so we can make a safer battery.
所以我们可以做出一种更安全的电池
I always work with many students and
我总是和学生们一起工作
they work hard to do experiments.
他们做实验非常努力
My name is Wenting Chen,
我叫陈文婷
I study organic electrolytes.
我学习的是有机电解质
I help to synthesize the organic electrolytes,
我帮着合成有机电解质
and help to do the battery tests.
以及测试电池
I’m Seongjae Ko,
我是金圣宰
I’m studying new electrodes and electrolyte material.
我学习的是新型电极和电解质材料
I help to synthesize those kinds of materials,
我帮着合成这类材料
and to assemble the batteries
以及组装电池
The electrolyte for commercial lithium-ion batteries
商用锂离子电池的电解质
has been almost unchanged over 20 years.
在过去近二十年都没有变过
So there is large room for improvement.
因此改进空间很大
The electrolyte is composed of salt and solvent
电解质由盐和溶剂组成
and we find that the concentration of salt is very important.
我们发现 盐浓度非常重要
The most interesting feature of the concentrated
高浓度电解质最大的特点是
electrolyte is stability against high voltage.
在高电压下能保持稳定性
Better batteries will be a key technology
更好的电池将是发展便携式设备
for portable devices and electric vehicles.
和电动车辆的关键技术
It is also useful for mass energy storage.
这一技术对大规模储能也同样重要
So we can utilize unstable renewable energy
我们可以更好地储存像太阳能这类
such as solar power.
不稳定 可再生的能源了
So I can imagine that we will all have a home energy
我想以后每家都会有一个
storage system for a household in the future.
家用能源存储系统
This means we can use energy more efficiently.
这意味着我们能更高效地使用能源
Also, if the power goes out during a disaster
另外 如果灾难发生 供电中断
we can continue to use electricity for several days or weeks.
我们在几天或几周内 仍有电用
