Manufacturing Process

Saku's manufacturing process is described as similar to laser printing, allowing for high-speed production at low costs. This approach could revolutionize battery manufacturing, making it more accessible and cost-effective.

Testing Saku's Battery Technology

Munro & Associates, known for their thorough evaluations of new technologies, conducted a series of tests on Saku's battery cells. These tests aimed to verify the claims made by Saku and assess the performance and safety of the new battery technology.

Capacity Tests

The first set of tests focused on verifying the energy storage capacity of the Saku batteries. These tests confirmed that the cells could store the claimed amount of energy, matching the specifications provided by Saku.

DCIR (Direct Current Internal Resistance) Test

Given the unique properties of the polymeric current collector, measuring the internal resistance of the battery was crucial. The DCIR test helped determine whether the higher resistance would interfere with the battery's ability to deliver current effectively.

Nail Penetration Test

One of the most impressive demonstrations of Saku's battery technology was the nail penetration test. This test is standard in the industry and is known to cause catastrophic failures in traditional lithium-ion batteries.

The test procedure was as follows:

1. A Saku battery cell was connected to an LED light to demonstrate its functionality.
2. The cell was then placed under a press with a nail.
3. The nail was driven through the battery cell.

The results were remarkable:

• The LED light went out momentarily when the nail penetrated the cell, indicating a short circuit.
• Unlike traditional lithium-ion batteries, there was no fire, explosion, or even smoke.
• After removing the nail, the LED light came back on, showing that the battery continued to function.

This test highlighted the exceptional safety features of Saku's battery technology. The ability to withstand such severe physical damage without causing a thermal event is a significant advancement in battery safety.

Gunshot Test

In a more extreme demonstration of the battery's robustness, a Saku battery cell was subjected to a gunshot test. The results were equally impressive:

• The battery was connected to an LED light before the test.
• A round was fired through the battery.
• The LED remained illuminated throughout the event, not even blinking.
• After the test, the battery continued to function despite having multiple holes.

This test further emphasized the extraordinary safety features of Saku's battery technology, demonstrating its ability to withstand extreme physical trauma without failing catastrophically.
