At present, the lithium batteries of underwater robots that support high-current and high-rate discharge mainly include polymer lithium batteries and lithium iron phosphate batteries. LINKAGE batteries are also based on these two types of batteries in the research and development and manufacturing of high-rate discharge lithium batteries. There are many specifications.

1. Basic performance characteristics of high-rate polymer lithium battery:
(1) High-current discharge performance is excellent, explosive power, high discharge platform, high energy density, good cycle life, etc.;
(2) The discharge rate meets the highest instantaneous rate of 150C, continuous discharge at 45C, and fast charging at 5C;
(3) Using laminated technology, the internal resistance is smaller, which is more conducive to rate charging and discharging, and high-efficiency output performance;
(4) Better temperature stability during discharge, controlled within 65 degrees Celsius to prevent overheating and damage;
(5) The battery is ultra-thin, small in size, and extremely light in weight. It can be made into special-shaped batteries of various shapes and capacities, and the thickness can be 0.45mm.

2. The basic performance characteristics of high-rate lithium iron phosphate batteries:
(1) Higher discharge efficiency and better stability against 60℃ high temperature;
(2) Using laminated technology, the internal resistance is smaller, and the performance in terms of discharge and cycle life is higher;
(3) High-current discharge performance is excellent, explosive power, high discharge platform, high energy density, good cycle life, etc.;
(4) The discharge rate meets the highest instantaneous rate 150C, 90C discharge for 2 seconds, 45C continuous discharge, and 5C fast charging capabilities;
(5) The battery is ultra-thin, small in size, and extremely light in weight. It can be made into special-shaped batteries of various shapes and capacities, and the thickness can be 0.45mm.

As a professional manufacturer of high-rate lithium batteries, LINKAGE battery can not only provide customers with customized services such as integrated underwater robot batteries, competitive mecha robot batteries, rescue robot batteries, fire-fighting robot batteries, etc., but also according to customers’ other high-speed The rate battery application needs product projects to customize the program, and produce the battery power supply that meets the product application requirements.
