*Following marshall's comment below, I (sadly) had to completely re-write my original answer.*

A famous open conjecture of Paul Erdos, first stated about 80 years ago, is that if all subset sums of an integer set $S\subset[1,n]$ are pairwise distinct, then $|S|<\log_2n+O(1)$ as $n\to\infty$. (Here $\log_2$ denotes the base-$2$ logarithm.) In modern terms, a subset of an abelian group, all of whose subset sums are pairwise distinct, is called *dissociated*. Similarly to Erdos' original problem, one can ask how large can dissociated subsets of other "natural" sets in abelian groups be. Say, you are asking what is the largest possible size of a dissociated subset of the set $\{0,1\}^n\subset{\mathbb R}^n$, and this particular problem has been studied by a number of authors. It is known that the largest size of its dissociated subset is
  $$ \frac12(1+o(1))\,n\log_2 n; $$
see, for instance, [this paper by Bshouty][1] for details and a historical account.

Here is an argument showing that for $n=10$, at most $28$ vectors can be found. Quite likely, it can be pushed further to yield an even smaller bound.

Assuming that $S=\{s_1,\ldots,s_m\}$ is a dissociated subset of $\{0,1\}^n$, for each $i\in[m]$ and $k\in[n]$ write $s_i=(s_{i1},\ldots,s_{in})$ and $w_k:=s_{1k}+\dotsb+s_{mk}$. Choose $\epsilon_1,\ldots,\epsilon_m\in\{0,1\}$ independently of each other and randomly with ${\mathsf P}(\epsilon_I=0)={\mathsf P}(\epsilon_i=1)=1/2$, and let $X_k:=\epsilon_1s_{1k}+\dotsb+\epsilon_ms_{mk}$ $(k\in[n])$; thus, $X_1,\ldots,X_n$ are random variables with $X_k\sim B(w_k,1/2)$ and $\epsilon_1s_1+\dotsb+\epsilon_ms_m=(X_1,\ldots,X_n)$. 

For each $k\in[n]$, let $I_k:=\left[\frac12w_k-3,\frac12w_k+3\right]$ if $w_k$ is even, and $I_k:=\left[\frac12w_k-\frac52,\frac12w_k+\frac72\right]$ if $w_k$ is odd; notice, that $I_k$ contains exactly seven integers in any case. An easy computation shows that for any $w_k\le n$ (recall that $n=10$), one has $X_k\notin I_k$ with probability not exceeding $\frac{11}{512}$; hence, $X_k\in I_k$ holds *for all $k\in[n]$* with probability at least $1-n\cdot\frac{11}{512}=\frac{201}{256}$. We now observe that $X_1\in I_1,\ldots,X_n\in I_n$ means that $\epsilon_1s_1+\dotsb+\epsilon_ms_m\in I_1\times\dotsb\times I_n$, the probability of which is $2^{-m}T$, where $T$ is the number of subsets sums of $S$ (that is, the number of choices of $\epsilon_1,\ldots,\epsilon_m$) that fall into the box $I_1\times\dotsb\times I_n$. However, since $S$ is dissociated, the number of such subset sums does not exceed the total number of integer points inside $I_1\times\dotsb\times I_n$, which is $7^{10}$. As a result, we get
  $$ \frac{201}{256} \le 2^{-m}\cdot7^{10}, $$
and $m\le 28$ follows readily.
