225A BATTERY - GS AUDIO 40*34 H19cm - 30 CELLS LTO - 14V + BMS AND BARS

Lithium titanate (LTO) batteries differ from conventional lithium-ion batteries in the composition of the anode. In these cells,lithium titanate oxide (Li₂TiO₃) replaces graphite (carbon), typically used in conventional batteries. The cathode can be lithium manganese oxide (LMO) or lithium manganese cobalt oxide (NMC).

At the microscopic level, the LTO has a three-dimensional structure composed of lithium titanate nanocrystals. This configuration enables an operating voltage of 2.4 V, fast charging, and the ability to withstand discharge currents up to 10 times its rated capacity.

Benefits of LTO technology

One of the main strengths of lithium titanate batteries is the greater surface area available for electron passage. The anode has a surface area of about 100 m² per gram, compared with only 3 m² per gram in conventional 3.7 V lithium-ion batteries. This feature enables extremely fast charging and a significantly longer service life. LTO batteries can be recharged in 6-10 minutes, compared with the 8 hours required for standard rechargeable batteries. In addition, they providemore than 98% charging efficiency.

Safety and thermal stability

The lower operating voltage of 2.4 V offers significant advantages in terms of safety and environmental impact. The absence of carbon in LTO cells reduces the risk of thermal instability and overheating, eliminating a major cause of fires in conventional storage systems.

Independent tests conducted on LTO batteries have shown that, even in the event of a short circuit, the maximum temperature reached does not exceed 90-100°C, without causing explosions or fires. This makes them a much safer solution than LiPo (lithium-polymer) batteries, which can be prone to spontaneous combustion in case of failure.
