China’s position in the global race for alternative EV batteries is critical as companies worldwide invest in emerging technologies. At the Beijing Auto Show in April, CATL, the world’s largest electric vehicle (EV) battery maker, showcased the Shenxing Plus battery. This remarkable battery can power an EV for over 1,000 kilometers on a single charge and can reach a range of 600 kilometers with just a 10-minute charge, according to Gao Huan, CATL’s chief technology officer.
LFP vs NMC Batteries
Currently, commercial EVs use two main types of lithium batteries: lithium iron phosphate (LFP) and nickel manganese cobalt (NMC). NMCs have greater energy density, while LFPs are safer and cheaper, particularly due to the high costs of cobalt and nickel. LFPs are more environmentally friendly as cobalt and nickel can be harmful to humans and ecosystems.
The Push for Next-Generation Technologies
Driven by cost-cutting and reducing supply chain bottlenecks, global companies are racing to develop new battery technologies. These innovations could benefit the environment by lowering carbon emissions. As noted by Chinese economist Ren Zeping, superior battery technology is the core of advancing the EV market.
Emerging Sodium-Ion Batteries
Chinese companies started focusing on sodium-ion batteries due to soaring lithium carbonate prices. Sodium is abundant and can be extracted from sea salt. CATL launched its first-generation Sodium-ion Battery in 2021, with other local firms following suit. Sodium-ion batteries are cheaper and sustainable but have lower energy density compared to Lithium-ion batteries. They are ideal for low-speed vehicles and energy storage applications due to their reliability in cold temperatures.
China’s Strength in Sodium-Ion Technology
China rapidly advanced in the Sodium-ion Battery sector. Patents filed by Chinese entities have significantly outnumbered those from other countries. The country has also launched the first mass-produced EVs powered by sodium-ion batteries, leading the global market.
The Future of All-Solid-State Batteries
All-solid-state batteries replace liquid electrolytes with solid ones, offering higher energy densities, improved safety, and longer lifespans. Companies like Toyota and BMW are investing heavily in this technology despite its high production costs. These batteries are crucial for the future but face challenges in manufacturing.
The race to dominate the EV battery market is heating up, with China at the forefront due to its aggressive innovation and production strategies. The country’s advancements in both sodium-ion and solid-state batteries could shape the future landscape of EV technology.
