November 7, 2024 – TLAB New Energy and Changan Automobile Collaborate on Revolutionary Membrane-Free Solid-State Lithium Battery Technology
BEIJING – On November 7, 2024, TLAB New Energy, in partnership with Changan Automobile, held a press conference to unveil their latest innovation in battery technology: a membrane-free solid-state lithium battery. During the event, Dr. Gao Xiang, Chairman & CTO of TLAB New Energy, introduced the technology, marking a groundbreaking advancement in the electric vehicle (EV) battery industry. TLAB’s “material reduction manufacturing” approach represents a new paradigm in battery design and production, with the potential to drive a revolution in the EV market.
4-3-2-1 Technology Roadmap for a Solid-State Future
At the heart of TLAB’s innovation is its proprietary 4-3-2-1 technology roadmap, designed to transform lithium-ion battery manufacturing from liquid-based cells to semi-solid and fully solid-state cells. The roadmap encompasses the following stages:
- Step 1 – Removal of the Membrane and Partial Electrolyte: This initial phase focuses on producing a semi-solid battery by removing the traditional membrane separator and part of the electrolyte. This version of the battery will be the first to enter mass production and is set to be integrated into vehicles for on-road testing.
- Step 2 – Complete Electrolyte Removal: In this stage, TLAB will eliminate all liquid electrolyte to create a fully solid-state battery. This version is expected to power low-altitude applications, such as drones and electric aviation.
- Step 3 – Removal of the Anode: In the final step, TLAB aims to create a battery with no anode, advancing toward a next-generation anode-free solid-state battery that could drastically improve energy density and reduce weight. This final phase will solidify the transition from liquid to semi-solid and eventually to full solid-state battery solutions.
This step-by-step approach provides a clear pathway for TLAB and Changan to transition from conventional liquid electrolyte batteries to more advanced semi-solid and fully solid-state alternatives, suitable for a wide range of applications.
Enhanced Safety and Cost Efficiency with Membrane-Free Batteries
The elimination of the membrane component represents a major technological breakthrough. In comparison to traditional liquid lithium batteries, the membrane-free semi-solid battery offers superior safety performance, even under extreme conditions. The product has undergone rigorous safety tests that surpass national standards, ensuring high levels of reliability.
Moreover, TLAB’s membrane-free technology reduces dependence on traditional separator materials, which contributes to a cost reduction of over 10% in raw material expenses. By streamlining production and increasing material efficiency, TLAB has enhanced both the economic viability and the scalability of their solid-state batteries.
Strategic Partnership with Changan Automobile
In light of their ongoing partnership, Changan Automobile recently became a stakeholder in TLAB New Energy, and the two companies have committed to a comprehensive collaboration model that includes joint R&D and business cooperation. During the event, TLAB and Changan further outlined a timeline for the mass production of membrane-free batteries:
- 2026: Semi-solid membrane-free battery to undergo vehicle installation testing, with the goal of meeting the needs of the EV market.
- 2027: Full-scale production of membrane-free solid-state batteries for demonstration applications in specialized fields.
The partnership aims to capitalize on both companies’ strengths to deliver next-generation batteries that address the core challenges facing the EV industry: safety, cost, and performance. This collaboration between TLAB and Changan positions both companies at the forefront of the global shift towards solid-state technology, with a focus on sustainability and efficiency.
Setting a New Standard in Battery Safety and Efficiency
According to Dr. Gao Xiang, TLAB New Energy’s commitment to innovation has culminated in the achievement of membrane-free solid-state battery technology, which offers substantial improvements in both safety and cost-efficiency compared to existing battery solutions. The semi-solid battery format promises a safer, longer-lasting alternative that meets the needs of modern electric vehicles and other emerging technologies.
Changan Automobile representatives at the event expressed confidence that this innovative battery will significantly enhance the company’s future EV models, aligning with their vision of promoting sustainable energy solutions and reducing carbon emissions.
As global demand for electric vehicles continues to grow, advancements in battery technology like TLAB’s membrane-free solid-state battery are essential for the industry’s evolution. This new technology not only represents a breakthrough in battery design but also underscores China’s leading role in the development of green technology.
