固态电池将实现电动汽车的主导地位

虽然锂离子电池已成为电动汽车电池系统的主要解决方案，但它们也存在一些局限性。其中之一是能量密度仍然不太高，另一个是与刺穿电池的枝晶生长和电解质有时着火有关的安全问题。

Solid-state batteries are expected to become a key technology for electric vehicles (EVs) in the coming years, promising to offer higher energy density, faster charging times, and improved safety compared to traditional lithium-ion batteries.

固态电池预计将在未来几年成为电动汽车（EV）的关键技术，与传统锂离子电池相比，有望提供更高的能量密度、更快的充电时间和更高的安全性。

Several companies are working on developing and commercializing solid-state batteries, including QuantumScape (QS +0.46%). Here's a closer look at the company's technology, recent developments, and potential in the EV battery market.

多家公司正在致力于固态电池的开发和商业化，其中包括 QuantumScape (QS +0.46%)。以下是该公司在电动汽车电池市场的技术、最新发展和潜力的详细介绍。

QuantumScape Batteries

QuantumScape 电池

QuantumScape's solid-state batteries use a unique lithium metal, anode-free design. Anode-free batteries store lithium ions in an electrochemical deposit of alkali metal directly on the current collector, rather than using a separate graphite anode.

QuantumScape 的固态电池采用独特的锂金属、无阳极设计。无阳极电池将锂离子直接存储在集电器上的碱金属电化学沉积物中，而不是使用单独的石墨阳极。

This design enables higher cell voltage, lower cell cost, and increased energy density compared to conventional lithium-ion batteries.

与传统锂离子电池相比，这种设计可实现更高的电池电压、更低的电池成本以及更高的能量密度。

QuantumScape's batteries are also designed to be safer, with a solid ceramic electrolyte that eliminates the risk of dendrite formation and potential battery fires.

QuantumScape 的电池设计也更加安全，采用固体陶瓷电解质，消除了枝晶形成和潜在电池火灾的风险。

Solid State Companies

固态公司

While QuantumScape is a prominent player in the solid-state battery space, it's important to note that other companies are also pursuing this technology.

虽然 QuantumScape 是固态电池领域的知名企业，但值得注意的是，其他公司也在追求这项技术。

Here are a few notable examples:

以下是一些值得注意的例子：

Solid Power (SLDP +0.09%) is another U.S.-based company developing sulfide solid-state batteries for EVs. Its batteries aim to achieve high energy density, long cycle life, and low cost.

Solid Power (SLDP +0.09%) 是另一家为电动汽车开发硫化物固态电池的美国公司。其电池旨在实现高能量密度、长循环寿命和低成本。

Toyota Motor (TM +0.08%) has been heavily involved in solid-state battery research and plans to introduce them in its EVs by 2027. The automaker is working with several partners, including Hino Motors, on developing and mass-producing solid-state batteries.

丰田汽车 (TM +0.08%) 一直大力参与固态电池研究，并计划到 2027 年将其引入电动汽车中。该汽车制造商正在与包括日野汽车在内的多家合作伙伴合作，开发和大规模生产固态电池电池。

Hyundai Motor (HYMLF -1.13%) is also pursuing solid-state batteries through its partnership with Factorial Energy. The companies aim to develop and produce high-energy density solid-state batteries for Hyundai's EVs.

现代汽车 (HYMLF -1.13%) 也在通过与 Factorial Energy 的合作来开发固态电池。两家公司的目标是为现代电动汽车开发和生产高能量密度固态电池。

Overall, the solid-state battery market is still in its early stages, with several companies competing to commercialize the technology. As EVs become more mainstream and the demand for advanced batteries increases, we can expect to see further developments and innovations in this space.

总体而言，固态电池市场仍处于早期阶段，多家公司竞相将该技术商业化。随着电动汽车变得更加主流以及对先进电池的需求增加，我们预计会看到该领域的进一步发展和创新。
