题目：
In the next few years, battery technology is going to grow rapidly.
No more charging your smart phone every day...
No more “range anxiety” for electric cars, as new lithium batteries （锂电池）allow them to drive hundreds of miles on a single charge, just like a tank of gas.
And a tiny Chinese company is to be the leader of it all.
It already counts Motorola, Nokia, and Samsung as customers for its advanced batteries.
But the real money is going to come when it starts selling electric cars.
Right now, the stock is trading at an extreme discount, offering in-the-know investors a chance to get in and make a killing.
