What are All-Solid-State Batteries?

LEAD‘s all-solid-state battery & EV battery pack design

All-solid-state batteries are a groundbreaking energy storage technology that replaces the liquid or gel electrolytes in conventional lithium-ion batteries with solid electrolytes. This design enhances safety by reducing the risk of fires and leaks while enabling higher energy density, which extends battery life and improves performance. The use of solid electrolytes allows for more compact designs and greater efficiency, making them a compelling alternative for electric vehicles and grid storage applications.

Despite their potential, large-scale production of all-solid-state batteries remains challenging due to limited expertise in mass production and best practices.

However, the R&D team at LEAD is actively working to enhance manufacturing techniques, optimize production processes, and develop cost-effective materials to enable large-scale manufacturing.

LEAD has already developed advanced equipment, including the film lamination machine, dry electrode high-efficiency shearing mixer, dry process twin screw mixer, dry process film forming and lamination machine.

Benefits of All-Solid-State Battery Technology

Faster charging times

Consumers can fully charge the battery in under 10 minutes. All-solid-state batteries enable faster ion movement, reducing charging duration significantly compared to traditional lithium-ion batteries.

Higher energy density

Potential of greater than 400 Wh/kg, meaning more energy storage capacity per unit of weight. This allows electric vehicles to achieve longer driving ranges without increasing battery size.

Greater power density

All-solid-state batteries can deliver higher instantaneous power output, making them ideal for applications requiring rapid energy discharge, such as electric vehicles accelerating or high-performance electronics.

Longer lifespan

With reduced electrolyte degradation and minimal dendrite formation, all-solid-state batteries can endure significantly more charge and discharge cycles, leading to improved longevity and reduced replacement costs.

Enhanced safety

The absence of flammable liquid electrolytes minimizes the risk of leaks, fires, and explosions, offering improved stability and safer battery operation.

Greater thermal stability

Solid electrolytes are more stable at higher temperatures, reducing the risk of overheating and thermal runaway, which is common in conventional lithium-ion batteries.

Maximizing Energy Density with All-Solid-State Batteries

EV battery energy density has progressed from 180 Wh/kg to over 400 Wh/kg. Nickel-rich oxides and silicon-based anodes improved lithium-ion batteries, while all-solid-state cells with high-energy NMC and lithium metal anodes will enable higher efficiency, longer range, and enhanced safety. With these advancements, all-solid-state batteries achieve significantly higher energy densities than traditional lithium-ion batteries, paving the way for next-generation EVs.
