A lithium-ion battery is indispensable to our life.

However, sufficient security is indispensable on the structure of a lithium-ion battery.

This testing machine is equipment for doing the trial examination of "the compulsive internal shorts" which is one of the safety assessment examinations of a lithium-ion battery.

Nail-Testing Equipment which Yamamoto metal techno have developed can extract data on all conditions.

At our company, first, in order to help you to understand the capability of a testing machine or a nail, we deal with a demonstration menu called gcommissioned examination.g

We are waiting for your inquiring.

Specification (Thermo-nail®)

This nail is developed by Yamamoto metal@technos with deep hole drilling tech.
Therefore, It is possible to insert the thermo couple of various size.
The following table shows the size example of standard type.

Feature

1.you can survey temperature exactly!!

We developed the nail which can insert temperature sensor by the deep hole driling tech.
Libcy

2. You can setup various test conditions !!

A lithium-ion battery is used for a variety products is the way of portability of energy.
In other words, it will be necessary to examine assumed various usage environment.
This testing machine can perform various kinds tests to meet the demand for safety and reliability.

Number of nail

It is possible to examine simultaneously with one to maximum five nails.
In large-sized Nail-Testing Equipment, limit to when the field size of a battery exceeds a 100-mm square.
Libcy

Speed of testing nail

In this machine, you can set speed of testing nail from2to20 mm/sec.
It can be stopped during the examination.

Form of a nail

With our high technology, we can process the nail.

3. You can carry out pressure test !!

This testing machine can be applied to "pressure test" which is one of the safety assessment examinations of a lithium-ion battery.

Since the hydraulic press machine is used, pressure test can be contacted by replacing a nail for the parts of pressure test. it is realizable by exchanging a nail for the part for pressure test

* It can be set to a maximum of 100 kN(s).
The part for pressure test serves as an optional order.
Libcy

4.Good temperature response

Thermo-nail is excellent in the temperature response.
The following table shows the rise condition of temperature when thermo-nail and a thermo couple directly dip into hot water.
When thermo-nail dip into 55 cm, there is almost no difference in both response.
It is very dangerous to thrust a thermo couple into a lithium-ion battery directly, and to measure temperature.
you can measure a temperature simply by inserting thermo-nail which does not have a difference in the temperature response into lithium-ion battery.

FAQ for example

Q:I have Nailing-test machines, already.
@ Can I buy only fthermo-nailf from your company?
@ Can I attached it to my machines?
A:You can buy thermo-nail without Libcy.
@we can prepare the nail of two shapes for you.
And, when you attach the thermo-nail to your nailing-machines,
We will make an attachment for you and/or shape an special-thermo-nail.
