Low Temperature Battery

There is an increasing demand for batteries that can operate in harsh conditions, including extreme temperatures, without leaks or ruptures.  The LTO batteries from Nichicon are low temperature batteries that can continue to operate in temperatures as low as -30℃ with a very low risk of ignition or explosion.

What is a low temperature battery?

A low temperature battery is a battery with low temperature characteristics that allow it to continue to operate in temperatures below 0℃.  For standard lithium-ion batteries, their resistance increases when the temperature drops to about 0°C which limits the energy storage of the battery and extends its charging time and decreases its capacity. The lithium-titanium-oxide (LTO) batteries made by Nichicon hold around 50% of their charge and discharge capacity at temperatures as low as -30°C.

The reason standard lithium-ion batteries have difficulty operating and charging at temperatures below 0°C is because the lithium ions are less likely to be absorbed by the graphite anode and condense as lithium metal.  When lithium metal condenses, dendrites form that can penetrate the separator between the cathode and anode which leads to an internal short circuit. When an internal short circuit occurs, a high current passes through the short circuit which generates heat that causes decomposition within the electrolyte.  The cathode, anode, and electrolyte react to the heat, resulting in sparks and the release of oxygen which creates an oxygen combustion reaction.  This can set off a chain of exothermic reactions that cause thermal runaway and fire.

What are the advantages of Nichicon low temperature batteries?

The LTO batteries from Nichicon avoid The charging capacity at -30°C may decrease to about 52% and the discharge capacity can decrease to about 46%.  The resistance in standard lithium-ion batteries can cause   Nichicon’s LTO batteries can operate safely in cold temperatures.

What are the advantages of Nichicon low temperature batteries?

Nichicon low temperature batteries can remain operational in extremely low temperatures and only lose about half of their charge/ discharge capacity in temperatures as low as -30°C.  They are also much safer to use in low temperatures than standard lithium-ion batteries because the titanium anode is not easily subject to

FREQUENTLY ASKED QUESTIONs


The lithium titanate battery (LTO) shares many characteristics with the lithium-ion battery. One difference is the LTO anode. An LTO battery uses lithium titanate oxide, while a lithium-ion battery uses carbon. By using lithium titanate, the battery has a significant performance improvement.


The SLB is a battery with long leads, just like a standard capacitor. The leaded profile allows for soldering directly to the circuit board using hand soldering or a select solder technique. Lithium Titanate batteries require an additional mounting bracket or holder placed on a circuit board. The Nichicon SLB (LTO) take less board space allowing them to be used in very compact or densely populated circuit boards.


LTO batteries are safer; they have an extremely small risk of ignition if there is a short. The SLB, Nichicon’s LTO battery, has superior charge and discharge capabilities, such as a 20C charge rate. Even higher rates are possible with pulsed discharges, like those used in telecommunications.


‘The SLB can withstand up to 25,000 charge/discharge cycles and have a lower cold temperature rating than a lithium-ion battery. And its low internal resistance allows energy harvesters to charge with weak currents without loss. They will not ignite if a short occurs. In addition to the advantages previously mentioned, the SLB comes in aluminum electrolytic case styles and size.


LTO batteries offer significantly greater capacity and exhibit minimal leakage current compared to electric double-layer capacitors, enabling them to be discharged over extended durations. Rechargeable LTO batteries of smaller size deliver an astonishing 20-30-fold increase in energy when compared to equivalently sized double-layer capacitors. Leveraging this advantage, our LTO batteries can effectively serve as a viable alternative to electric double-layer capacitors, delivering sustained power output for prolonged periods.


Our LTO batteries excel in rapid charging, discharging, and longevity, surpassing the capabilities of standard lithium-ion batteries while offering enhanced safety. Achieving high power discharge is a challenging feat for conventional lithium-ion rechargeable batteries, but our LTO batteries effortlessly handle it with superior charge/discharge performance and remarkably quick charging times. The rapid charging capability of LTO batteries makes them perfect for devices that demand swift charging intervals or situations where charging may be interrupted or inadvertently overlooked.
