Product Description

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.
