固態電池將實現電動車的主導地位

雖然鋰離子電池已成為電動車電池系統的主要解決方案，但它們也存在一些限制。其中之一是能量密度仍然不太高，另一個是與刺穿電池的枝晶生長和電解質有時著火有關的安全問題。

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.

固態電池預計將在未來幾年成為電動車（EV）的關鍵技術，與傳統鋰離子電池相比，有望提供更高的能量密度、更快的充電時間和更高的安全性。

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.

多家公司正致力於固態電池的開發和商業化，其中包括 QuantumScape (QS +0.46%)。以下是該公司在電動車電池市場的技術、最新發展和潛力的詳細介紹。

QuantumScape Batteries

QuantumScape 電池

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 的固態電池採用獨特的鋰金屬、無陽極設計。無陽極電池將鋰離子直接儲存在集電器上的鹼金屬電化學沉積物中，而不是使用單獨的石墨陽極。

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

與傳統鋰離子電池相比，這種設計可實現更高的電池電壓、更低的電池成本並提高能量密度。

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 的電池設計也更安全，採用固體陶瓷電解質，消除了枝晶形成和潛在電池火災的風險。

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.

雖然 QuantumScape 是固態電池領域的知名企業，但值得注意的是，其他公司也在追求這項技術。

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%) 是另一家為電動車開發硫化物固態電池的美國公司。其電池旨在實現高能量密度、長循環壽命和低成本。

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.

豐田汽車(TM +0.08%) 一直大力參與固態電池研究，並計劃在2027 年引入電動車中。固態電池電池。

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.

現代汽車 (HYMLF -1.13%) 也正在透過與 Factorial Energy 的合作來開發固態電池。兩家公司的目標是為現代電動車開發和生產高能量密度固態電池。

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.

整體而言，固態電池市場仍處於早期階段，多家公司競相將該技術商業化。隨著電動車變得更加主流以及對先進電池的需求增加，我們預計會看到該領域的進一步發展和創新。
