Lithium titanate battery with photovoltaic panel

What is a lithium titanate battery?

Lithium titanate, or lithium titanate oxide (LTO) batteries, are rechargeable batteries that use lithium titanate oxide as the anode material. These batteries fall under the lithium titanate classification. Their chemistry is based on the exchange of lithium ions between the cathode and the anode.

Are lithium titanate batteries better than other lithium ion chemistries?

Lithium titanate batteries offer many advantages over other lithium-ion chemistries, including: Longer cycle life. Increased safety. Wider working temperature range. Faster charge/discharge rates. However, energy density is relatively low among these batteries. In addition, high C-rates inevitably impact the battery’s capacity over time.

What is the storage capacity of a lithium-titanate battery?

It has a storage capacity of 5.4 kWh and a depth of discharge of 90%. Shenzhen Kstar Science and Technology (Kstar) has launched new all-in-one residential lithium-titanate (LTO) batteries for residential PV systems. A LTO battery is a lithium-ion storage system that uses lithium titanate as the anode.

Are lithium titanate batteries safe?

Lithium titanate batteries are considered the safest among lithium batteries. Due to its high safety level, LTO technology is a promising anode material for large-scale systems, such as electric vehicle (EV) batteries.

What are the limitations of lithium titanate (LTO) batteries?

One of the primary limitations of lithium titanate (LTO) batteries is their cost. They are more expensive than other lithium-ion batteries, such as lithium iron phosphate. Another limitation is their capacity.

How long does a lithium titanate battery last?

Typically, a battery reaches its end of life when its capacity falls to 80% of its initial capacity. That said, lithium titanate batteries’ capacity loss rate is lower than for other lithium batteries. Therefore, it has a longer lifespan, ranging from 15 to 20 years.
