E-Mobility: the key role of lithium batteries
Lithium-ion (Li-ion) batteries play a fundamental role in e-mobility. Thanks to their performance in terms of autonomy, power and durability, they are enabling the development of cleaner, more efficient means of transport. But what are the real advantages of these batteries? And what challenges still need to be met to accelerate the transition to 100% electric mobility? Here's how.
Differences Between NMC and LFP Lithium Batteries: Our complete Guide
In terms of lithium battery technologies, two types dominate the industry: NMC (Nickel-Manganese-Cobalt) and LFP (Lithium-Fer-Phosphate) lithium-ion batteries. These two chemistries offer distinct performances and are suitable for different uses. This guide explores their differences to help you understand which option to consider for your needs.
Trends: the evolution of the lithium battery market
