Many overseas solid-state battery companies exist, whereas...zuiNotably, there are automakers with a background and strong capabilities in the field of liquid lithium batteries.

Solid Power

When it comes to Mercedes-Benz, it's inevitable to mention BMW. BMW has partnered with a solid-state battery company.Solid Power。
This is a company established inIn 2011, the American company developed the core technology of solid-state battery, with its electrolyte material. Besides BMW, it also collaborated with Ford, Volta Energy Technologies, and SK Innovation, among others.
BMW andSolid Power's partnership began in 2017, initially focusing on advancing the application of all-solid-state batteries in high-performance electric vehicles. In 2021, Solid Power announced the completion of a $135 million Series B financing round, led by the BMW Group, Ford Motor Company, and Volta Energy Technologies. Ford and the BMW Group also expanded their existing joint development agreement with Solid Power to secure all-solid-state batteries for future electric vehicles.
In 2021, Solid Power announced the expansion in Thornton, Colorado..Two Denver-area production facilities. The new factory will significantly expand.Solid Power enhances its capability to produce key materials for its all-solid-state batteries, including the capacity to manufacture up to 30 metric tons of sulfide-based solid electrolyte materials annually, which represents a 25-fold increase in current production capacity.

Backed by a research team from Stanford University, Volkswagen has invested in QS twice, making itzuiMajor Shareholder; Company2019: Listed on the New York Stock Exchange as the.A publicly listed solid-state battery company.
In December 2022, QuantumScape delivered its first batch of 24-layer solid-state battery samples to partners, including Volkswagen.
In March 2024, Volkswagen Group's battery-focused subsidiary, PowerCo, completed a durability test using QuantumScape's solid-state batteries. The results prove that these batteries can achieve an extraordinary lifespan of over 500,000 kilometers with minimal degradation.
QS's solid-state battery technology boasts two major highlights:
A new oxide ceramic membrane has been developed to act as a solid electrolyte between the positive and negative electrodes.NCM-composed gel-like material with polymers.
Battery lacks a true negative electrode; during charging, lithium ions from the positive electrode cross through the ceramic membrane to accumulate on the other side, forming a lithium metal negative electrode. During discharge, the lithium metal negative electrode vanishes and transfers back to the positive electrode material.
