"Xiao You, so you're saying that if this graphene battery is used for a phone, wouldn't the phone not need to be charged for a year or more?"
When Ding Yue heard his sister say that the charging speed and endurance of this graphene battery are over 1000 times that of a regular lithium battery, he thought about the implications of using it in mobile batteries. Wouldn't this eliminate the worry about phone battery life?
"You are a postgraduate student, how can you think such a thing?"
To his surprise, Ding Yue was hit with his sister's sarcastic retort.
"Huh?"
Ding Yue, still caught in the thrill and surprise, hasn't quite processed her words yet.
Director Xiao Wenxing, standing off to one side, had a perplexed look on his face. Weren't they saying it was at least a thousand times better? If it were used in mobile batteries, wouldn't it indeed not need charging for a year or more?
