 This is the aluminum battery we have. It's made of aluminum and graphite. Both materials are quite cheap. Right now it's lighting up LED light and you can bend it and still you can see the LED light is still on while you are bending it. Similarly as this, we have two batteries with a cell phone. So it can provide like five volts and it can be charged within a minute. It's possible to have like bendable cell phone with bendable screen. You have bendable batteries on the back and it's it's great. This is a lithium-ion battery which we use a lot in our daily lives for example in our cell phone and in our laptops. Commonly lithium-ion battery if you drill a hole through the battery or like probably it's catch on fire but our aluminum battery is non-flammable. So if you drill the hole through it, it's still running. For a while it's definitely a high-safety battery we have and it has a reasonable capacity and a very long cycle life. It has no decay over hundreds of cycles, even thousands of cycles. So you can have a potential application in like great-scale electric storage. So it's quite exciting. I think it can be further improved and this is a great start. We think that it has a bright future.
