Battery Tech

The MTB technology integrates the battery module directly into the vehicle's bracket or chassis, allowing for a 40 percent increase in battery system utilization and a 10 percent weight reduction.

Condensed battery cells have features including high safety, reliability and good cycle life, said Wu Kai, CATL's chief scientist.

The M3P battery is based on a new material system developed by CATL and has a higher energy density than LFP batteries and a lower cost than ternary batteries.

The cells have an energy density of 350-400 Wh/kg and has now successfully passed tests including pin prick and 200°C hot box tests, Svolt Energy said.

This follows reports that CATL plans to mass-produce LMFP battery, which its chairman mentioned in February as the M3P battery, within this year.

The battery's energy density is 15-20 percent higher than that of lithium iron phosphate batteries, but there is little difference in the material costs, according to local media.

The all-solid-state battery cells show excellent cycling performance, with 71 percent capacity retention even after 20,000 cycles.

When CATL announced the Qilin Battery last week, it said the battery could be charged to 80 percent in as little as 10 minutes. The latest battery technology it teased cuts that time even further.

The technology enables batteries to achieve fast charging rates of 2C and above, with a lifetime of more than 1.5 million kilometers, GAC said.

Robin Zeng did not provide more information on this, although he himself has a PhD in condensed matter physics.
