11.Handling Instructions
Read and observe the following warnings and precautions to ensure
correct and safe use of Li-ion batteries.We are not responsible for
any issues arising from violating the following precautions.
Super Mini-Shape Rechargeable Lithium Titanate Battery Cell LTO
2.4V3mAh
Lithium titanate battery cell is a kind of rechargeable battery
which uses titanic acid as anode material. lt hasunbeatable
advantages in rapid charge, long service life, higher safety and
wider working temperature thanother lithium ion batteries.
Lithium titanate batteries are a modifed lithium-ion battery
because they use extra lithium titanatenanocrystals on the anode
surface rather than the carbon materials used in other lithium-ion
batteries. Thisgives the anode a surface area of ca. 100 square
meters per gram, but the carbon-based material only canachieve 3
square meters per gram, allowing electrons can be faster enter and
leave the anode quickly. ltmakes lithium titanate battery can be
faster recharge and support high working current when request.
Brightening up your prototypes with superior LTO Battery cell -
Excellent Safety, Longer Battery Life, Fast Charge andWider
Operating Temperature.
