Penghui Energy, a cutting-edge energy company based in Guangzhou, China, has made a groundbreaking announcement regarding its latest development in solid-state battery technology. The company has successfully created a solid-state battery with an impressive energy density of 280 Wh/kg – surpassing the current capabilities of top-level lithium-ion batteries, which typically achieve around 250 Wh/kg.
However, what sets this Chinese battery apart is not merely its superior energy density but its remarkably affordable price. Remarkably, the new solid-state battery costs only 15% more than the standard battery currently employed in modern electric vehicles. This significant cost reduction marks a significant step forward in making solid-state battery technology more accessible.
One of the major accomplishments for Penghui Energy was overcoming the obstacles associated with the production of oxide solid-state electrolytes. Traditionally, oxide electrolytes require high temperatures during production, resulting in the ceramic material becoming overly brittle. In response, Penghui Energy devised a revolutionary wet coating process for the electrolyte, eliminating the need for excessively high temperatures and simplifying production.
By streamlining the production process, Penghui Energy has successfully reduced costs to a level comparable to that of a standard lithium-ion battery. Looking ahead, the company aims to achieve cost parity within the next 3-5 years through further optimization of the process and material handling. These anticipated optimizations are also expected to elevate the energy density from the current 280 Wh/kg to an even more impressive 300 Wh/kg, a projected achievement before mass production commences.
The solid-state battery developed by Penghui Energy boasts a long service life of 600 recharge cycles and operates efficiently within a temperature range of -20°C to approximately 85°C, making it a highly versatile solution for various applications.
Penghui Energy plans to begin a small-scale pilot research program and initiate limited production in the coming year, with full-scale production slated to commence in 2026. This remarkable breakthrough by Penghui Energy represents a significant stride towards revolutionizing battery technology and driving the widespread adoption of electric vehicles in the near future.
