In our storage systems with Carbocap Technology we use LTO cells. These are non-flammable and non-combustable according to UL-1973 certification. They offer a high C-rate and therefore high performance. With 20,000 cycles this technology leads in comparison with other cells. Several cycles per day are possible and the longevity of the cells makes them particularly sustainable. During the lifetime of an LTO cell, other cells would have to be replaced twice.
The following graphic shows the features of the cells used.
In 2018, TU (University of Technology) Graz compared different lithium-ion batteries and presented the outcome at an symposium. The electrode types considered were lithium iron phosphate (LFP), lithium titanate (LTO), lithium nickel manganese cobalt oxide (NMC), lithium nickel cobalt aluminum oxide (NCA) and lithium manganese oxide (LMO).
Here we briefly present an extract of the results. You can find the complete paper here: Ecological and Economic Performance Stationary Li-Ion Battery Storage, 15th Symposium Energy Innovation, February 14-16, 2018 Graz University of Technology.
