丰田计划在 2027 年推出电动汽车用全固态电池

2023-06-13 23:05:00 by 天渊

电动汽车的性能很大程度上取决于电池。目前充电时长和充电 1 次的可行驶距离都不如汽油车和混合动力车。以丰田“bZ4X”为例,用锂离子电池的充电时间约 30 分钟,续航距离约 600 公里。丰田正在研发全固态电池,该公司表示投入市场的时间为 2027~2028 年,能实现充电 10 分钟行驶 1200 公里。全固态电池与液态锂离子电池不同,电解质是固态,特点是充电时间短,可延长续航距离。固态电解质和固态电极必须紧贴在一起,不能分离。充放电造成电极反复膨胀和缩小的话,电解质和电极就会分离,导致无法使用。此前一般只能充放电数十次~数百次,无法达到实用化所需要的数千次以上。丰田称它已经解决了固态电池的耐久性问题。

Pinterest (PINS) Stock Sinks As Market Gains

Pinterest (PINS) closed at $71.75 in the latest trading session, marking a -0.18% move from the prior day. This change lagged the S&P 500's daily gain of 0.1%. Meanwhile, the Dow gained 0.9%, and the Nasdaq, a tech-heavy index, lost 0.59%. Heading into today, shares of the digital pinboard and shopping tool company had lost 17.41% over the past month, lagging the Computer and Technology sector's loss of 5.38% and the S&P 500's gain of 0.71% in that time. Investors will be hoping for strength from PINS as it approaches its next earnings release. The company is expected to report EPS of $0.07, up 170% from the prior-year quarter. Our most recent consensus estimate is calling for quarterly revenue of $467.87 million, up 72.05% from the year-ago period.

Export WhatsApp stickers to Telegram on iPhone

You can’t. What you can do, though, is use WhatsApp’s and Telegram’s web platforms to transfer stickers. It’s easy, but might take a while.Open WhatsApp in your browser, find a sticker you like in a chat, and right-click on it to save it as an image. The file won’t be a picture, though—it’s a webpage and will have a .webp extension. Don’t be scared, this is the way. Repeat this step to save as many stickers as you want.Then, open Telegram in your browser and go into your Saved messages chat. Just as you’d share a file with a friend, click the Share file button on the bottom left of the chat window (it looks like a dog-eared paper), and select the .webp files you downloaded. Click Open and you’ll see your stickers in your Saved messages chat. This is now your sticker depository. To use them, forward them as you would a message from one chat to the other: by clicking or long-pressing on the sticker, and then choosing Forward.
