Sand Battery Origin: Correcting Misleading Claims About Who Built It

Recently, some articles were published about Sand Battery in Vietnam.

Some of you asked me about why there is only 1 face and the origin of the Sand Battery were not detailed, often brushed over and mislead. Some reported that the timeline is inconsistent, sometimes it's 2021, sometimes it's 2023.

Here are such purposefully misleading PR examples, where the origin of Sand Battery made in Vietnam was not clear:

IF You want to know the real story, not half-truths:

Follow the full Sand Battery saga. In which for the first time, I'd share photos and videos that I've kept from the beginning of the creation, way before the Sand Battery was named.

This matters because attribution is not a cosmetic detail. When a technology story is compressed into a clean PR narrative, the dates, prototypes, contributors, and decisions that actually shaped the work can disappear. That does not only distort public understanding. It also affects how readers interpret inventorship, ownership, and the credibility of later claims around patents, startup history, and who carried the technical work in the early days.

If you want to evaluate the Sand Battery origin story properly, compare the timeline across the posts, photos, and patent context rather than relying on a single summary article. Start with

What Is a Sand Battery?

for the core technical concept, then read

The True Origin

for the early development record, and

the USPTO patent post

for the formal patent context. Taken together, those posts give a much more complete picture than a repackaged press mention.

I am keeping this note short on purpose. Its role is to point readers toward the primary record instead of letting vague or inconsistent summaries stand on their own. If a public claim says the work started in the wrong year, omits the technical timeline, or presents the origin as if it appeared fully formed much later, treat that as a signal to go back to the documented trail and verify the sequence yourself.

Here's the first part of the series:
