This new technology is said to provide the battery with a lifetime of over 100,000 cycles which is much higher than that of conventional batteries.
Mahle Powertrain and UK-based Allotrope Energy have together unveiled a new battery technology that could revolutionise EV charging. Called lithium-carbon technology, it offers ultra-fast recharging with good power density. It would suit a wide range of small EVs, including e-scooters.
Lithium-carbon technology has been created by combining the benefits of supercapacitors and traditional lithium-ion batteries. The result is a battery cell that can be recharged quickly and still retain good energy density. It is also stable at high temperatures and thus, permits high current delivery and fast recharging.
This new technology is also said to provide the battery with a lifetime of over 100,000 cycles which is much higher than that of conventional batteries. The lithium-carbon cells are fully recyclable and free from rare-earth metals.
Mahle Powertrain and Allotrope Energy carried out a collaborative project. According to the details, if a food-delivery electric moped with a 25 km range and a 500 Wh lithium-ion battery, require a recharge mid-shift, it would take more than 30 minutes even with a fast charger. However, a lithium-carbon pack could be recharged at 20 kW in just 90 seconds.
Dr Mike Bassett, MAHLE Powertrain’s Head of Research, pointed out that with ultra-fast charging, the size of the batteries can be optimised depending on the vehicle and its purpose. Also, the reduced battery size will lead to weight and cost savings.
