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。

How to Invest in Bitcoin?

Like a stock, you can buy and hold Bitcoin as an investment. You can even now do so in special retirement accounts called Bitcoin IRAs. No matter where you choose to hold your Bitcoin, people’s philosophies on how to invest it vary: Some buy and hold long term, some buy and aim to sell after a price rally, and others bet on its price decreasing. Bitcoin’s price over time has experienced big price swings, going as low as $5,165 and as high as $28,990 in 2020 alone. “I think in some places, people might be using Bitcoin to pay for things, but the truth is that it’s an asset that looks like it’s going to be increasing in value relatively quickly for some time,” Marquez says. “So why would you sell something that’s going to be worth so much more next year than it is today? The majority of people that hold it are long-term investors.”

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
